The request-uri in SIP message when outbound call through VCS Expressway-E

[limerez01]

Hey guys.

     I found something been changed in the SIP message of VCS Expressway-E.

     When a terminal registered on CUCM calls an external server or terminal, the Request-URI  was  changed .I captured the diagnostic package for CUCM and VCS Expressway,the CUCM normally forwarded SIP message, but VCS changed it (delete the callee number in request-URI and user part).

    What can I do to prevent VCS from modify messages？Thanks.

packet CUCM to VCS:

packet VCS to external:

VCS search rule:

VCS has always done manipulations based on your search rules or transform rules. The search rule you attached is stripping the prefix pattern. Have you tried "leave" rather than strip?

As Ayodeji say your rule in VCS is set to strip the part that your highlight as missing in the captures. Set it to Leave and you should be good on this point.

Indeed, it worked when I changed Behavior to "leave",thank you very much.
