[SR-Users] Contact header modification - Kamailio

[Ankit Jayswal]

Hello,
Yes, actually my call flow for outbound calls is, Kamailio => Asterisk =>
Kamailio (route(PSTN)). SIP trunk is available at Kamailio server.
So, when final outbound INVITE goes to the SIP trunk provider it expects a
particular Contact header IP, instead of Asterisk server IP.
