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

Hello,
to clarify, in the REGISTER you sent and pasted again below, from
Contact:
<sip:OTT919620649614@125.16.231.74:25841;ob><sip:OTT919620649614@125.16.231.74:25841;ob>
you want to have:
Contact:
<sip:OTT919620649614@185.122.205.178:5070;lr><sip:OTT919620649614@185.122.205.178:5070;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.
Cheers,
Daniel

Hi Daniel,
I am attaching here my sip trace at client side.Request you to see this.
My client IP in register request is 125.16.231.74 and the server on which kamailio is
running is 185.122.205.178.
I want my contact header to be
<sip:OTT919620649614@185.122.205.178:5070;lr><sip:OTT919620649614@185.122.205.178:5070;lr>
I am using avp_subst() function to replace this.But kamailio is not starting.
Please reply if I am in wrong way or have different understanding as I am very new to
kamailio.
Thanks,
Narayan

Subject: RE: Not able to replace route_uri in contact header uri
Hi Daniel,
Thanks for your response.
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
3333@172.22.13.41<mailto:3333@172.22.13.41>.
I want my contact header to be 3333@185.122.205.178<mailto:3333@185.122.205.178>.
So how can I replace the contact header's only domain part with route_uri.the user
part of the contact header remains same.
Thanks,
Narayan
