Can anyone explain the default behavior of CUBE in regards to caller ID in a SIP-to-SIP environment?
This is our setup: CUCM 7.x <----sip---> CUBE <----sip-----> Paetec SIP service
The recommended configuration from Cisco for Paetec is to use "no remote-party-id" in the sip-ua configuration. However, I should still be able to get named caller id in the FROM header. I see names being passed to us from Paetec, but CUBE strips the names in the TO and FROM headers of the INVITE message.
The only documentation i can find regarding SIP and clid are concerned with ISDN to SIP. I need to understand the SIP to SIP clid behavior and how I can manipulate it. This is the only Cisco documentation I have found so far: http://www.ciscosystems.com/en/US/docs/ios/12_4t/12_4t4/FeatTP.html#wp1079374
We are using the latest version of code on the gateway - 12.4(24)T3
Here is an example of what I see on the packet trace. IP's and numbers have been changed for privacy.
