How to stripping the prefix in 2811 Voice Gatway?

Unanswered Question
Nov 11th, 2009


We have a voice gateway 2811 and a single CUCM7 cluster. We configured CUCM7 to not remove the prefix (9) as per our billing application software requirements. So we now need to have the gatway do that. My question is:

How can I configure the gatway to strip the digit "9" prefix before sending the call to the PSTN? I think I need to use the translation rule command but I am not sure what is the syntax. Can anyone help with an example?


I have this problem too.

POTS dial-peers already strip exact matches.

destination-pattern 9XXXXXXX would strip the 9 and send only 7 digits to the PSTN

I'm assuming H323 because MGCP cannot do this, MGCP needs you to remove the 9 at CUCM.

Are you using H323? If so, you should have a dial-peer similar to this one:

dial-peer voice 1 pots

destination-pattern 91[2-9]..[2-9]......

forward-digits 11

By specifying the last command, gateway will send only 11 digits to PSTN and exclude '9'

On the 2811 gateway are you using MGCP or H323?

If you are using H323 you should just be able to modify the dialpeers by making the destination pattern 9T.
