    Answers
  1. How do I setup the DPCB to work with my phones?

    Look on the back panel of the blue retail box or on page 1 of the ProSeries II Call Blocker Manual for instructions on how to connect the DPCB. You can also watch the ProSeries Blocker Overview Video below. The color figure as seen in the DPCB manual shows the LINE cable connected to your telephone source, usually the telephone wall plate.
    1. Connect the supplied (white) line cord to your telephone wall jack and then to the LINE Port on the Call Blocker. Note in the diagram the Line cord is highlighted in dark blue. You must connect the Line cord and your phone to the correct ports in order for the Digitone Call Blocker to operate properly. Initially, "Connect to Line Service" will show on the display until the Line cord is plugged into the LINE port. "Connect to Line Service" will display if the Line cord is disconnected afterwards.
    2. Plug the small end of the Power Supply into the port labeled "24VDC" on the Call Blocker, next plug in the Power Supply to a 120VAC wall receptacle.
    3. Connect your combo Phone/Answer Machine system to the TEL phone port of the Call Blocker and set to 3-5 rings. Note if you are using Voice Mail services from your phone company, then don't enable any answering devices there in your home or office. DPB Overview Video

  2. Is Caller ID Name Blocking possible on the DPCB?

    YES.
    Block Button - Names Entry
    This feature only works with the Block button on calls you have already received in Call History and not in Programming. Block up to 50 individual names (except OPX names) with or without numbers that use the same name with different numbers. Using the Call History Up or Down view buttons, Tap the Block button Once quickly on the selected Name you want to block. The display will show "Save Name Block? To store that name, Tap the Block button again and then the display will show "Name Block Saved". From then on, any number with the Name you stored will be blocked.

    Example name with different numbers: Phoenix 602 555 1212, Phoenix 480 555 1212, Phoenix 623 555 1212. Each of these calls are blocked in this example. This one entry of Phoenix [name blocked] has a virtual unlimited number of calls it can block.

    Block Names Removal
    Using Code 44 in Programming to view Blocked Names list to find the name you want to unblock. Names can only be removed with this function in programming. Use arrow buttons to view up or down to find the Name entry you want to remove. To remove or unblock a Name entry press the Delete Entry button Once, the Display will ask "Confirm Delete?" Press the Delete Entry button again to confirm. The Name will then be removed from that list.

  3. Will the DPCB work with VoIP services like: Vonage, Ooma or Magic Jack as my phone service provider?

    Yes! Vonage, Ooma and Magic Jack are internet based phone services that use an Ethernet Analog Telephone Adapter (ATA) which provides you with a Phone port. Your phone is connected there now but you will simply disconnect your phone and connect the DPCB's LINE to that port then connect your phone to the DPCB's TEL phone port. Blocked callers will not ring your phone but all other calls will pass through.

    Return to top
  4. Does the DPCB work with any phone service?

    Call Blocker Compatibility - Digitone's ProSeries II Blocker works with all makes of analog telephony equipment and on all U.S. Domestic and Foreign standard 2-wire telephone lines with FSK/DTMF (ETSI) Caller ID, DSL, FIOS, VoIP, Cable Modems and Digital services using (ATA) adapters from Skype, Vonage, Ooma or Magic Jack and ATT Uverse. The DPCB is designed specifically for public telephone network FCC provisioned landlines.

  5. Can I use my cordless or extension phones to remotely block a caller?

    YES. You can remotely block or invite a caller using your cordless phones or any phone connected to the line to either block or invite a caller. Using your phone and dialing * 2 # will block the LAST incoming caller who called in. Alternatively, you can dial * 1 # to invite the caller for when using Select Mode or * 3 # to make that caller a VIP who can ring through at any time.

    Return to top
  6. Does the DPCB keep the phone from ringing at all, when it receives unwanted calls?

    Yes the DPCB has First Ring Suppression built-in which prevents phones connected to the TEL port from ringing on the first ring. All other phones connected directly to the phone company will ring once. Your options to avoid the first ring is to connect your phones to the DPCB and turn off the phones connected directly to the phone company. You can also use a cordless phone system to distribute the ringing around the house instead. This will avoid the first ring completely. Caller ID is also repeated to all phones connected to the DPCB.

    Return to top
  7. Can I program the DPCB to block specific numbers, area codes and spoofed exchange numbers?

    Yes. Go into Programming and use Code 40 to enter the area code(s) you want to block or Code 40 to block specific numbers; Ex. 40 602 555 1212 *.

    Spoofed numbers like 2, or ---6-- are all hungup on in Standard Mode by default and you don't have to do any programming. However, if the number is 10 digits with just numbers, but the number is not actually a working number like; 555 555 5555, then you can just block that number or the whole area code of 555 in Programming with; 40 555 * for example.

    Spoofed Exchanges 000 and 111 are blocked by default others like [555] in the number: 602-555-1234, which is the second set of 3 digit numbers after the area code of 602 in this example, can be blocked using Code 20 then 555 *. Other number sets can be blocked as well besides 555, like 000, 111, 222, 333, etc.

    Return to top
  8. The DPCB display shows "Connect to Line Service"; what does this mean?

    Connect to Line Service means the DPCB is not connected to a valid phone service source. When you installed the DPCB, you should have used the supplied line cord, because it is new and it only connects the red and green pair of the first line to the DPCB. If you are using another wire cable with more than two conductors, it's possible that the wiring is not connected properly to the source. There is a possibility that the yellow and black pair, which normally is the second line, is somehow reversed on the DPCB side and is not making a connection. There is also a possibility that the wall plate is not wired correctly if you have an older home. When the DPCB is finally connected to a phone source, "Connect to Line Service" will disappear and the DPCB will go to idle mode.

    Return to top
  9. Does the DPCB repeat Caller ID information to the telephones connected to the TEL port?

    Yes, the Caller ID is captured and repeated to all phones downlinked to the TEL port. If you have a corded phone or cordless phone system base connected there, then all corded phones and cordless handsets to that base will receive the repeated Caller ID. When a call comes in, the phone company's Caller ID information will display on the DPCB and ring all extension phones with caller ID connected to the telephone line, but the DPCB will only suppress the first ring to the TEL port to prevent it from ringing and receiving Caller ID. If the caller is an Invited caller, then the Caller ID information will display on the first ring to the phones connected to the TEL port thereafter. This stops unwanted Caller ID information from Blocked callers from being received by the phones connected to the TEL port, like Out of Area, Unavailable, Anonymous or a Blocked caller's number.

    Return to top
  10. How do you set the time and date for VoIP caller ID?

    1) The date and time are determined by your local phone service automatically, but you can manually set it for use with VoIP phone services like Magic Jack*. This function corrects the foreign clock time zone (or possibly none) to your local time zone. Press and hold the Program Button for 3 seconds until you see Program Mode, then Pick Up Phone, when the prompt for Enter Code displays, enter 95 followed by the year in two digits, the month in two digits, the day in two digits and the (Military) time in 4 digits. Example, 95 16 02 20 1425 * or 95 + Year 16 + Month 02 + Day 20 + Mil Time 1425 (2:25PM) + * key to store. The display will show the new Time and Date changed immediately after you hang up and for each call thereafter. To return to factory setting of Automatic Date & Time, enter 95 # *.

    2) Do not manually set the Time and Date if you already have full Caller ID Name and Number service. The date and time are determined by your phone service but if some phone services (like VoIP) do not send the date and time with the name and number, you can manually set it as above.

    3) Note that VoIP services may use only one Time Zone (like Magic Jack*) to indicate the time of the incoming call. So, if you are using the DPCB in the Pacific Time Zone (PST) at 3:00 PM and a call comes in through a VoIP service that only uses Eastern Time (EST), the time may be indicated as 5:00 PM or 6:00 PM depending on daylight savings. This will look incorrect for your time of day and also adversely affect any settings you have set for After Hours Mode.

    Return to top
  11. How do I enter into Programming?

    The DPCB must be connected properly to an analog telephone line source in the LINE port, with an analog telephone connected to the TEL port. There must be power connected to the DPCB by the Digitone power adapter supplied with the DPCB.

    Programming : With your phone connection setup done,
    1) (Preferred) Take the Phone in the TEL port offhook and dial ## or *** to go directly into programming and wait for the BEEP, the display will now show "Enter Code" or,
    2) press and hold the Program Button for 3 seconds until you see "Program Mode", then "Pick Up Phone". This prompt tells you to pick up the handset to your corded or cordless phone. Note that if you are using a cordless phone system you will also have to press the Talk button. When you pick up the phone handset connected to the TEL phone port on the back of the Call Blocker, the display will now show "Enter Code". You must remain on the line with your phone offhook when programming, so don't hang-up the phone. Enter any program code listed in the manual by simply dialing that program code with the phone's keypad to set caller lists or features.

    Return to top
  12. If I clear display, I want to know if the numbers end up on the blocked list?

    Clearing the display does not add the numbers to the blocked list. Only Programming can delete stored blocked numbers or you can invite a number that was blocked if it is still in the Call History list using the Invite button.

    Return to top
  13. Can I allow my neighbor to ring through who blocks his caller ID using "Private" when he dials *67?

    Yes by using Code 74 in Programming. Or.. you can also tell your neighbor to dial *82 before also dialing your number and his Caller ID Name and Number will display on the screen allowing the call to come through.

    Return to top
  14. My family members call me from overseas and their number displays as "Out of Area"; can I let them ring through?

    Yes by using Code 76 in Programming. Note however, that this will allow all other Out of Area callers to ring through as well.

    Return to top
  15. Can I use the wildcard string to block as example, all of the 800 series area codes, ex. 40 8## ### ####?

    Yes. Enter Programming and when the "Enter Code" displays: dial 40 8## ### ####*. This will block all calls beginning with 8, including valid area codes like 801 for Utah, 804 for Richmond, 805 for Ventura, etc.

    Return to top
  16. I have Ooma Business VoIP service that has Cisco IP telephones; Can I use the ProSeries II to block calls?

    Yes. The ProSeries II can block calls Only if you also have an Ooma Telo unit connected in parallel to your router/switch ethernet ports where the Cisco IP phone is also connected. The Cisco IP phone will get its DHCP address from the router and so will the Telo. The Telo in turn will provide analog telephony through its Phone port to the ProSeries II which can read the same Caller ID data that the Cisco phone is receiving. The Telo is required in order to do this processing and may even come with the Ooma Business service. Be sure to ask for the Telo when ordering the Ooma Business service. See Ooma Telo.

    Return to top
  17. How can I use Select Mode to control my calls?

    Select Mode is used to separate calls from Invited, Blocked and Voice Mail/Answer Machine. In Select Mode, calls that are scammers will not ring your phone and instead will be processed by your answer machine or voice mail. Callers you want to hear from just need to be invited using the Green Invite button on each call already in Call History or preload them into programming. Each invited caller you add will ring through like normal.
    You can also Block caller's Names or Numbers not already blocked by the automatic system with the Red Block button. To use Select Mode enter programming:
    1) (Preferred) Take the Phone in the TEL port offhook and dial ## or *** to go directly into programming or,
    2) press and hold the Program Button for 3 seconds until you see "Program Mode", then "Pick Up Phone". This prompt tells you to pick up the handset to your corded or cordless phone. Note that if you are using a cordless phone system you will also have to press the Talk button.
    The display will now show "Enter Code". Simply dial 33 and Select Mode will now be in operation.

    Return to top
  18. How do I let calls through that are Out of Area?

    Calls that come in as Out of Area are blocked by default as many scammers use their cell phones to avoid detection. Out of Area was always a response by the phone company for unidentified calls whose Caller ID Name was not presented by the initiating station. Today, many cell phone companies do not take the time to register owners names, including family members, to their cell phones and instead, just use Out of Area as the Name.
    However, you can allow the Number displayed with Out of Area to ring through by simply making that Number an Invited caller or a VIP. Use the Green Invite button on the call displayed and press it twice to add it to the VIP list or press and Hold for the regular Invited list.
    If you want to allow all Out of Area callers to ring through, then enter Programming and use override Code 76.

  30. Will the DPCB work with previous Digitone Call Blockers and with my fax machine?

    YES. Your fax machine can be connected anywhere on the line like in another room or on a duplex jack with the DPCB and/or your answer machine. If you have a fax machine with CNG tone detection, and it normally captures a calling fax from the line, then the DPCB will not interfere with this operation.
    Use a standard duplex jack to connect both units to the Line and then connect phones to just the new ProSeries II Call Blocker. The Fax machine will then continue to monitor the line as before without having to change anything. Alternatively, you can connect either unit to its own wall plate in different rooms and still get the same results.

    Return to top
  31. Can I block all callers and just invite certain people to ring in?

    Yes and you will use Code 97 # * in Programming to block all calls. Then use the Invite command 50 then the invited caller's number; ex. 602 555 1212, then the * key to store that number. You can also store whole area codes. Code 60 is also available for inviting VIP callers using Code 60.

  32. Will the DPCB work in conjunction with Verizon Wireless T2000 Service or AT&T Wireless Home Phone?

    YES. Verizon provides a means to have your home phone line work with cell phone (wireless) service via Verizon's or AT&T's CDMA cellular network. The receiver unit, can operate as a standard line emulator that works like regular telephone service, where you send and receive calls. The receiver provides regular analog phone service to your phones and the DPCB like normal.

    Return to top
  33. How does the DPCB interact with Call Waiting or Call Waiting Caller ID service?

    The DPCB ignores Call Waiting and Call Waiting Caller ID service when you are on the phone. Your phone will display Call Waiting Caller ID if you have that service or you will hear a beep tone to alert you to a call waiting. Blocked callers you have on your blocked list will not be blocked by the DPCB during call waiting. The DPCB cannot both let you talk on your current phone call and then also block the incoming caller.

    Return to top
  34. Our AC power is subject to many outages in our neighborhood; What can we use to support the DPCB?

    It is highly recommended the DPCB be connected to a Uninterruptible Power Supply (UPS) for extreme cases where the line needs to be conditioned properly due to motor hash noise or poor service. If your home or office receives regular low voltage blackouts, power surges or power outages consider purchasing this UPS backup power supply or surge protection for both the phone line and AC line conditioning that can support up to 1800 watts for about 15 minutes. This device can be purchased separately at Amazon or at most electronics and office supply stores. If you already have one, connect the power adapter there to support it during power issues.

    Return to top
  35. Do I need a surge protector for my line and power?

    Yes, and we recommend the Belkin Model F9H620-CW surge protector. You can save a ton of aggravation when your home or office is struck by an electrical storm and damages many of your connected electronics, in particular, the DPCB. Both the telephone line and the power line are surge protected with this Belkin model. The cost alone is less than the shipping, time and repair it will take to get your DPCB back online and in service.

    Return to top
  36. Will emergency notification telephone devices like "Life Alert" still function properly connected on the line with the DPCB?

    Yes, when connected anywhere on the line in any room other than where the DPCB is connected or in parallel with a duplex jack at the same location.

    Return to top
  37. Can I program the DPCB at one place and move it to another, then install it without doing any other programming?

    Yes. The DPCB has non-volatile memory which allows it to store all your caller lists and user settings without losing any of the data when the unit is unpowered.

    Return to top
  38. A telemarketer is calling me using my own phone number; Can I block my own phone number displayed?

    Yes, because you cannot actually call your own phone number. If you dial your own phone number you will just get a busy signal because you are on the line.

    Return to top
  39. I have Call Announce that announces the phone number; Will the DPCB announce a Blocked caller?

    NO. If you have the Call Announce device connected to the TEL port of the DPCB, AND the caller is blocked, it will not announce that caller. It will only announce Invited caller numbers.

    Return to top
  41. Does the DPCB have a Back Light control for extending the time for viewing the LCD?

    YES. The new back light for the DPCB has a default time of 10 seconds, but you can add or subtract time to this default. Using the Code 27 in programming followed by the time in seconds 0 up to 60. So, code 27 00 * equals back light OFF, 27 20 * is 20 seconds of back light time, etc.

  42. Something is seizing the line (offhook) for a few seconds after hanging up; Does the DPCB do this?

    1) NO. You may be using a Panasonic cordless phone or other device that momentarily takes the line offhook after 15-30 seconds. The DPCB does not return to the line like this for any reason. The other devices or phones just have a poor design that interrupts the line, possibly answering and terminating an incoming call from time to time. Suggestion: Remove that faulty equipment from the line.

    2) You have a second or third device on the line; like an alarm modem, an older separate Caller ID box or Fax Switch device with offhook functions, cordless phones that can create offhook events by 'checking the line' or a satellite TV receiver (Set Top Box) connected to the line that is either capturing the call right after the first ring or causing an offhook event that is accepted as though the call was answered. Any of these offhook events stops the DPCB from processing the call any further. Suggestion: Remove all devices from the line except the DPCB and a connected phone to the TEL port. Now try calling into the line to see if it works properly. If this works, then add your other devices one- at- a- time to see which one is causing the offhook event, then remove it from the line.

  43. Voicemail flashes a light on my phone indicating a message waiting; Does this work with the DPCB?

    YES. Notifications of voicemail messages is presented to all phones downlinked either by extension or through the TEL port. When there are messages waiting, your phone will display a Message Waiting indicator and you should still receive a stutter tone (SDT) from your phone company when you pick up the phone to let you know you have messages.

  44. Do I need to use a 1 before area codes when programming in blocked area codes and numbers?

    Calls that start with a Country Code, like 1 (USA) means you must enter the entire string into a blocked number. Example: to block the entire 800 and 1-800 area codes, enter programming and enter: 40 800 *, then 40 1800 *. You will then see area codes 800 and 1800 in the Blocked Callers List. This is only necessary if you receive both inbound call types of 800 and 1 800. For individual numbers the same holds true that the 1 must be inserted if you receive the call that way, ex. 1 602 555 1212 instead of 602 555 1212.

  45. Is there a way to clear numbers on the display without resetting the whole DPCB?

    To clear the CID display of all current calls just use the Delete Entry button. Press and hold the Delete Entry button for 3 seconds and the Display with ask "Delete CID List?" Tap the Delete Entry button again to confirm. This will clear all the record numbers displayed.

    If you just want to clear specific numbers, go to Call History and find the call record you want to clear, then Tap the Delete Entry button Once quickly for the displayed number you want to delete and the Display with ask "Confirm Delete?" Press the Delete Entry button again to confirm. Only the displayed number will be cleared.

  46. Do I have to create an invited list of my callers?

    No. By default ALL valid numbers from anywhere are invited and you don't have to invite them. Unless... you enable Global Blocked Method, Code 97 # * which then blocks everyone. This is when you would use Code 50 [ Number] * or Code 60 [Number] *. You can also still add specific callers to the Blocked List if needed.

    Return to top
  47. If I block all calls starting with "3" then ## ### ####, can I invite a number within that blocked string?

    NO. The 3 by itself is not an area code. When using a single digit before all other numbers, forces the program to block everything after that number. You will have to use full area codes in order to invite whole numbers within a blocked area code using code 52 to invite a number.

    Return to top
  48. Can I allow calls from certain area codes to ring through and make all other calls ring silently to voicemail?

    Yes. The DPCB now has Select Mode that allows you to force all calls go to voicemail or an answer machine in parallel to the LINE that's ringing with the DPCB connected. If your phones are connected to the TEL port then only the Line will be ringing and not your phones. As the calls come in, you can select which ones you want to add to the Invited Caller Lists Code 50 and Code 60 (VIP) up to a total of 160 callers or area codes. Also, using Codes 50 or 60 in programming, you can pre-load those callers into the lists and enabled Code 33 to turn on Select Mode which can only be enabled in programming.

    Return to top
  49. Do I need to purchase a second DPCB if I have a 2-line phone?

    Depends on if you just want to protect the first line only. The DPCB is a single line operation. If you need to cover a second line you should purchase a second unit. If you have a 2-line phone and you want to block both lines, then you will need a second DPCB. If you have a 2-line phone and only want to block the first line then you only need one DPCB using a 4 conductor phone cable. The second line will bypass the DPCB system.

  50. Can I get my DPCB repaired after a lightning strike?

    Yes, all models are still repairable even if they are out of warranty. Your model can be repaired for just the cost of shipping & handling in most cases for as little as $8.00. Please contact us at 877-610-5693 for an RMA to return your unit for servicing.

  52. Where can I install the DPCB; with or without DSL or on a Cable, FIOS, ATA system?

    The DPCB can be installed at any phone line source, including regular wall plate jacks, cable modem phone port, or FIOS, U-verse gateway, Vonage adapter phone port. Then connect your phones to the DPCB TEL port.

    Some of these digital services have been connected to your phone wall plate and telephone service is now distributed throughout your home using the house wiring. You can connect the DPCB to any of these wall plates.

    DSL service can have a whole house DSL filter installed at the demarc where individual DSL filters to every phone is not needed.

    Alternatively, you may have DSL filters for every phone or device in service on the line. In which case you just connect the DPCB to the DSL filter then to the phone service.

    Some DSL duplex filters have DSL Modem (ADSL) and Phone written on the filter jack, so you would connect the DPCB to the Phone port of that jack. If the DSL filter is a single port, then connect the DPCB to the DSL filter (shown above) where your phone was connected, then connect your phone to the TEL port of the DPCB.

    Some DSL duplex filters have DSL Modem (ADSL) and Phone written on the filter jack, so you would connect the DPCB to the Phone port of that jack. If the DSL filter is a single port, then connect the DPCB to the DSL filter (shown above) where your phone was connected, then connect your phone to the TEL port of the DPCB.

    If you have both DSL and cable systems, then the same is true for DSL above when you are using the PSTN line for voice communication (telephone service). A DSL filter would not be used on a cable modem if you get your telephone service there.

    Note that parallel connections like in the above examples only provide 1st Ring Suppression to the phones connected to the DPCB TEL. All other extension phones will ring once.

    Demarc of a House In a series connection, 1st Ring Suppression protection is provided to the whole house when the DPCB is either installed at the head end (demarc) of the house wiring before the phones or by connecting the DPCB in parallel as above and turning off the other extension phone ringers. A cordless phone system with many cordless handsets would then provide silence on blocked calls when the DPCB is connected this way.

    NOTE THAT THE DEMARC AS SHOWN HAS VOLTAGES THAT ARE AT LEAST 48VDC AT IDLE AND CAN BE AS HIGH AS 100VAC WHEN RINGING ON THE COLORED TERMINALS RED, GREEN, BLACK OR YELLOW WHICH CAN SHOCK YOU OR WORSE WHEN HANDLED INCORRECTLY. SO UNLESS YOU ARE TRAINED IN ELECTRICAL WORK, DON'T ATTEMPT TO MODIFY THE OUTSIDE CABINET TERMINAL CONNECTIONS. THIS IS A JOB FOR TRAINED TELECOM PERSONNEL AND SHOULD BE TRUSTED TO THEIR CAPABLE SKILLS.

  53. The red LED light flashes continuously, can I turn this off?

    The LED blinks mostly because there are new calls as indicated in the upper left hand corner of the DPCB screen. If there is an "N" displayed in the upper left of the display then there is at least one call that is new. You have to clear this by reviewing the newest calls near the End of List. The clearing of the display of all calls is the fastest way to eliminate the flashing. Otherwise, you have to review each call that is New indicated in the upper left corner of the display using the left Call History button until there is zero calls there. Alternatively, you can turn the LED off completely with Code 29 .

  54. Can the DPCB be wall mounted or stand up vertically?

    The DPCB comes will a wall mount hanger and has two slots on the back for attachment. If you don't want to mount the DPCB to a wall with screws, then use 2-sided Velcro strips for easy removal. Due to the tilted viewing angle of the DPCB for the preferred table top use, when mounting the unit vertically, the viewing angle is increased to a point where it is not easily read unless it is mounted above normal viewing height.

    Return to top
  55. What does the blocked caller hear when they are blocked?

    The blocked caller only hears one ring tone in their phone handset and then silence. After about 10 seconds, they will get a dial tone or busy signal depending on the service. The DPCB has no means to produce sounds or recordings, so it itself is silent.

    Return to top
  56. Can I block a call from the DPCB front panel keypad while the call is ringing in?

    YES. This is a function to the DPCB while it is actively receiving CID data during an inbound call. Wait for the DPCB to display the call, then Press and Hold the Block Button which will then stop the call and add the call to the Blocked Callers list.

  58. How do I setup voicemail service to work with my answer machine and DPCB?

    When you have voice mail service and you connect the DPCB to your home phone system, you may notice that your local answer machine cannot take calls like before and your callers cannot leave a message on your answer machine. That is because the DPCB has First Ring Suppression that blocks the first ring.

    Voice mail from your phone company is set to answer the call after 5 rings and simultaneously your answer machine is set to answer after 4 rings. Because they are both trying to take the call, only the voice mail will be able to, as it takes the call completely off the line away from your house to free up the line for another call. Simply set Voice Mail Ring Count to 6 or 7 rings to prevent this from happening.

  59. How can I get OPX calls answered by an answer machine and have preferred calls also answered?

    Connect an answer machine to any phone wall plate and set the answer delay to 4-6 rings, or 1-2 rings greater than the answering device in the TEL phone port. This separate answer machine will capture any uninvited calls not answered by the Combo Phone/Answering device in the TEL phone port.

    You will need a second answering system to take the OPX - Out of Area, Private and Unknown calls connected in parallel to the DPCB using a duplex jack shown here set with 1-2 rings greater than the answering device in the TEL phone port.

    Return to top
  60. How do I prevent the first ring on blocked calls?

    The DPCB prevents the first ring by default. However, all of your extensions phones not connected to the TEL port of the DPCB will ring once because they are still connected directly to the phone company.
    Digitone recommends that you use a cordless phone system connected to the TEL port to do the distribution of the ringing and then turn off the extension phone ringers, or obtain a multi-port modular 1-to-5 Adapter shown here and connect all your phone bases into it and then to the TEL port of the DPCB.

  61. How do I Unblock a number of someone I blocked?

    To unblock a number, simply find that number still in Call History and Press and Hold the green Invite Button, then "Number Invite Saved" will display to let you know it is not blocked anymore.

    However, if the number is now cleared and the caller is still blocked, it is possible you have blocked their Name or their entire area code. Go into Programming and look at Code 44 for their Name or Code 41 for their area code you may have blocked and delete that entry using the Delete Entry Button.

  62. Does the DPCB work with NEC, Avaya, Northern Telcom, Panasonic and other brands of PBX?

    The DPCB can work with these PBX systems if they are analog on the front end CO trunk inputs or through PBX configured analog phone ports. The DPCB will not work on digital Key Sets from the PBX.

    The DPCB is fully analog and works directly with analog trunk circuits to and from a PBX with analog CO inputs and PBX configured analog phone ports. The DPCB would simply be installed at the phone closet where the PBX is located and the line service would be fed into the DPCB first, then connected to the CO input of the PBX using the line cord supplied with the DPCB. Alternatively, the DPCB can be connected to any downlinked PBX configured analog phone port.

  64. I recently changed my phone service and none of my Blocked calls are being stopped?

    If you recently changed your phone service from a 10 digit service (POTS or regular landline) to an 11 digit service (like Vonage, ATT Uverse, VoIP) you may have noticed that the DPCB now doesn't work like it used to. This is because the numbers you stored all have just a 10 digit format but all your new calls now have 11 digits and they don't match. You will have to take inventory of the numbers you have stored in the Blocked, Invited, and VIP lists and then deleted them all. After that, you re-enter all those numbers with a 1 in front of each number, EX. 10 digit format 602 555 1212 now becomes 1 602 555 1212 (11 digits).

  65. My phone company says I have digital phone service;
    Does the DPCB work with this service?

    YES. The phone companies have been busy changing out their older analog central office switches into modern digital types that include the newer transmission method of VoIP using routers. However, the wires to your house have remained the same in most areas and all of your phone equipment is still telephonically analog, not digital. Your cordless phones use the DECT digital method of transceiving, but your voice and other sounds are still analog before being converted to digital.

  66. Will the new STIR/SHAKEN framework authentication TRACED ACT enacted into law be effective at stopping robocalls?

    YES and NO
    YES: Enacted by Congress in 2019, The TRACED ACT for FCC enforcement and implementation are meaningful Only for VoIP originated calls where VoIP technologies are used. Spoofed calls primarily originate from VoIP services, and because STIR/SHAKEN is an IP-based standard, STIR/SHAKEN framework authentication cannot be deployed on Legacy Circuit-Switched networks (regular analog telephone lines). Then the VoIP "types" of calls are bracketed into A (known), B or C (for unknown origin). This is when you get the SPAM? alert and the call still rings through.
    NO: Scammers can just bypass STIR/SHAKEN's technology by originating calls on a Legacy phone network. Once the call is originated, by law the telephone companies must complete the call. A call originator with an authenticated (subscriber's registered) number could claim to be an IRS representative when in fact it is a scammer attempting to steal the call recipient’s personal data. While the call originator isn’t spoofing the number, they can still be effective by changing tactics by registering blocks of numbers, make fraudulent calls, drop them, then get a new set of numbers to start the process over again.
    YES: Phone companies may deploy an Alert service with the call using "SPAM?" or "SCAM LIKELY" in the Name parameter, but too often the call is still answered without the called party's knowledge of the caller's ID prior to answering the call.
    NO: The alerts won't be 100% and some callers (your neighbor) may actually be compromised by a scammer using their number to place fraudulent calls. The VoIP database will then be a Work in Progress, forever. It is highly likely that the STIR/SHAKEN authentication will not prove to be an effective tool against the scammers, so long as phone companies continue to pass the calls to your home/office, due to infrastructure costs, bad databases, scammers using Legacy systems to infiltrate the PSTN telephony network, and subscribers who just don't want to participate in trying to figure out whooooz calling?
    Your only 100% protection will still be with Digitone's Patented ProSeries II Call Management technologies!
