Prefixing Digits on Calling Party Mask

jgentsch · ‎02-15-2008

I have an integration with a PBX using CCM6.1. DID's for the Cisco phones are routed from the PSTN, to the PBX, and across this integration. Calls from PBX phones are also routed across this integration. I want to prefix '21' on the CLID only if the CLID is a 4 digit number from another PBX phone and not from the PSTN. The issue here is I could globally do this for all 'Subscriber' calls and be done but I need to integrate with multiple PBX's and each integration would have to prefix a different 2-digit number to the a PBX call.

Is the only way for me to do this is with a H323 gateway and translation on there?

Absolutely. Using H.323, you should be able to do it on the inbound dial-peer. Use "voice translation-rule" and "voice translation-profile":

Theres no reason you cant do this with MGCP and translation patterns also.

Just create dedicated CSS's for your MGCP circuits and include the relevant translation patterns.
