Thanks for your kind Response Daniel,
Yes as you told with the requirement I have mentioned call will not reach client, I have explained my requirement in detail, My requirement is to establish a call between 2 SIP clients Alice and Bob which are using 185.122.205.178(Kamailio) as outbound proxy and registered to a SIP SERVER, I am not able to establish call between Alice and Bob, So I am trying to Replace the Contact header in Register request with Kamailio IP and then I will direct the Invite request to callee client using the data(Username to IP:port tuple) I have stored in Kamailio database. Please suggest me if you have better Idea than what i am doing Thanks & Regards Narayan ________________________________ From: Daniel-Constantin Mierla <[email protected]> Sent: Tuesday, April 18, 2017 1:04:38 PM To: Narayan P; [email protected] Subject: Re: Not able to replace route_uri in contact header uri Hello, to clarify, in the REGISTER you sent and pasted again below, from Contact: <sip:[email protected]:25841;ob><sip:[email protected]:25841;ob> you want to have: Contact: <sip:[email protected]:5070;lr><sip:[email protected]:5070;lr> If yes, then this doesn't look right at all, then the device cannot receive calls anymore. Maybe you can explain the purpose and then we may be able to offer some hints.

I mean to say, In my register request the route header i.e. route_uri is <sip:185.122.205.178><sip:185.122.205.178> and contact header is [email protected]<mailto:[email protected]>. I want my contact header to be [email protected]<mailto:[email protected]>. So how can I replace the contact header's only domain part with route_uri.the user part of the contact header remains same.
