Does Callcentric support 7 or 10 digit dialing?
Currently Callcentric does not support account level 7 and 10 digit dialing. This is something we may introduce in the future however until it is a stable feature we cannot give an ETA or exact date as to when such a feature may be available.

In the meantime users may configure their devices to support 7 or 10 digit dialing. Listed below are some of the more common devices and software which support 7 or 10 digit dialing:

NOTE: Please be aware that some hardware/software simply DO NOT support 10 or 7 digit dialing while some may only support either 10 or 7 digit dialing.

NOTE: NPA = Your local area code or the area code you want 7 digit dialing for.

NOTE: Please make sure to replace NPA with your desired area code for 7 digit dialing where indicated.

PAP2 and Linksys/Sipura Devices


Telco Systems AC-211


Innomedia SIP MTA-6328

Unfortunately since the Innomedia MTA does not support digit replacement in the dial string it is not possible to configure 7 or 10 digit dialing for this device.

Asterisk/Asterisk Derivatives

Asterisk offers the ability to configure very complex dial plans. Listed below is a dial pattern/rule you can add to your current asterisk Callcentric outbound route to add support for 7 or 10 digit dialing. Please make sure that you are configuring your dial plan properly and that the outbound route to Callcentric is accepting the calls you want to go out through it.



For pbxnsip creating a dial plan is very simple as it can be done easily from the web interface. Note that callcentric is the standard name of the Callcentric trunk and 9 is the standard prefix in our pbxnsip configuration guide. To configure your 7 and 10 digit dial plans simply navigate to your Dial-Plans page and make sure you have the following:



3CX also offers a very simple interface for configuring dial plans. By default the outbound route for Callcentric uses 9 as the qualifier so we make sure to strip 1 digit from the number dialed for ever pattern we add. Please use the information below to create outbound rules for Callcentric in order to enable 7 and 10 digit dialing:

7 Digit

Rule NameRule for Callcentric 7 Digit
Calls to numbers starting with (Prefix)9
Calls from extension(s)
Calls to Numbers with a length of8

Strip DigitsPrepend

10 Digit

Rule NameRule for Callcentric 10 Digit
Calls to numbers starting with (Prefix)9
Calls from extension(s)
Calls to Numbers with a length of11

Unfortunately Grandstream devices are not able to support 7 and 10 digit dialing properly. These devices allow you to add a prefix for all outbound calls, which would cause *123 to be sent out at 1*123...etc, which would come in handy if you want all of your outbound calls to prefix a 9 for example. However such a scenario would work in a PBX environment where 9 would select the Callcentric trunk. In short these devices do not support 7 or 10 digit dialing at this time.
