Yes it should, but only if “rewrite_contact” is set to “no” for the endpoint (chan_pjsip).

Subject: [SR-Users] Question on Contact Header on Kamailio 200 OK to PBX

Hi All,

Kamailio is sending a 200 OK back to an INVITE from Asterisk, and Asterisk is sending the ACK back but the AOR can’t be found in Kamailio

200 OK Kamailio to Asterisk with a contact of

Contact: <sip:fgectrdv@9ot28m83bkur.invalid;alias=128.147.123.1~63486~6;alias=128.147.123.1~63486~6;transport=ws;ob>

Asterisk ACK to Kamailio

Request-Line: ACK sip:fgectrdv@192.33.11.108:5060;transport=TCP;alias=128.147.123.1~63486~6;alias=128.147.123.1~63486~6;ob SIP/2.0

Shouldn’t Asterisk be using fgectrdv@9ot28m83bkur in the ACK? Or did Kamailio send Incorrect Contact?

Note: fgectrdv@9ot28m83bkur is the what Kamailio shows as AOR.

Thank you,

-Steve
