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 10.251.1.5 to peer-interface 172.27.33.93 (realm access-cale) - INVITE sip:firstname.lastname@example.org:5060 SIP/2.0
Outgoing URI from the SBC core interface 18.104.22.168 (realm core-cale) to our call server 22.214.171.124 - INVITE sip:vas1.phx1.voip.tnltd.net:5060 SIP/2.0
The number 6232291600 is being stripped from the request causing our call to fail. This only happens to calls from 10.251.1.5, 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.
