Change Caller-id from SIP-TRUNK CME

Dear All.

 

I have trouble with identifying by name for incoming connections comming from siptrunk. We have two PBX connected, Cisco CME - for desk phones (SIP Phones only) and Uniify OpenScape Business V2 for DECT calls. The problem is that Unify PBX only transmits the number (3 digits) via SIP-Trunk and this is displayed on the phone. I would like the name to be displayed.  We have no chance to set it on Unify PBX. Below is a typical SIP header during an internal call from 551 to 524.

Can I configure Cisco CME to substitute the string - warehouse - instead of 551, even though it is an incoming call from another PBX ?

Yes that is possible. For this you would need to use a SIP profile used in the inbound direction on the SIP trunk to the CME from Unify. Please note that it would need do this per directory number, so it's not a very scalable solution. See below for an example for the number given.

voice class sip-profiles 200
 request ANY sip-header From modify "From: 551 (<sip:.*@.*>)" "From: Warehouse \1"
response ANY sip-header From modify "From: 551 (<sip:.*@.*>)" "From: Warehouse \1" ! voice service voip sip sip-profiles inbound ! dial-peer voice <tag> voip voice-class sip profiles 200 inbound

You can test this with the SIP profile tester at this link.
