    I am fairly new to 3CX, and know some stuff in Cisco UCM, I know this topic has been brought up before in past Threads but i dont see any posts/replies to any of them after 2010-2011.

    I have successfully created a SIP Trunk between 3cx v11 to Cisco UCM 7.1.

    I've got two concerns:

    1. when making a call 3CX extension to Cisco extension, It only shows SIP Port # on the display. I dont see the 3CX extension that is calling on cisco phone. (Cisco to 3CX works).
    Here is the log:

    2. In order to make a successful call from Cisco to 3cx i had to add/change Source ID on 3cx
    Request Line URI: User Part Custom Field Custom Value "6504" which is my extension on 3cx
    based myself on this article: http://www.3cx.com/blog/docs/source-identification-issues/

    Here is Activity Log when it wasnt working

    Here is my question: what changes or additions do i need to make for the other 3cx extensions to work, when someone from cisco extension dials them.

    Any help is greatly appreciated

    We had a project where we needed to changeover one phone at a time meaning that the old phone system had to be retained until all were changed over. To make calls to the old Asterisk based system we used a bridge. This might work with one end slave, the other master. Another method, if retaining trunks, is to use a constant trusted parameter such as the IP address of the other PBX.
