Phone Number Being Stripped From A Call URI

(Doc ID 1936542.1)

Last updated on OCTOBER 31, 2016

Applies to:

Acme Packet 4500 - Version S-Cx6.0.x to S-Cz7.2.0 [Release S-Cx6.0 to S-Cz7.0]
Information in this document applies to any platform.


The phone number in the URI request header is being stripped by the SBC and we cannot determine why.


Incoming URI from to peer-interface (realm access-cale) - INVITE sip:6232291600@ SIP/2.0

Outgoing URI from the SBC core interface (realm core-cale) to our call server - INVITE SIP/2.0

The number 6232291600 is being stripped from the request causing our call to fail. This only happens to calls from, which has a session-agent configured. Calls from the other session-agents in realm access-cale do not exhibit this behavior.

I've attached a packet capture along with acme logs including a support-info.
