Hello,

skipping to understand exactly the purpose of what you want to achieve, if you want \
to replace the contact header uri with [username from old Contact]@[kamailio \
ip]:[kamailio port] , you can try this:

if(is_present_hf("Contact")) {

  remove_hf("Contact");

  append_hf("Contact: \
<sip:$(ct{tobody.user})@$Ri:$Rp><sip:$(ct{tobody.user})@$Ri:$Rp>\r\n)");

}

If doesn't work, let me know.

Cheers,
Daniel

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

<div class="PlainText">Hi Daniel,<br>
<br>
Thanks for your response.<br>
<br>
I mean to say,<br>
In my register request the route header i.e. route_uri is <a moz-do-not-send="true" \
class="moz-txt-link-rfc2396E" href="sip:185.122.205.178"> \
&lt;sip:185.122.205.178&gt;</a> and contact header is <a moz-do-not-send="true" \
class="moz-txt-link-abbreviated" href="mailto:3333@172.22.13.41"> \
3333@172.22.13.41</a>.<br> I want my contact header to be <a moz-do-not-send="true" \
class="moz-txt-link-abbreviated" href="mailto:3333@185.122.205.178"> \
3333@185.122.205.178</a>.<br> So how can I replace the contact header's only domain \
part with route_uri.the user part of the contact header remains same.<br> <br>
<br>
Thanks,<br>
Narayan<br>
