Hi, <br><br>sorry for my late reply.<br><br>I hardcoded the Contact header in dialog/dlg_transfer.c file. It is not a very elegant way, but I had a short time to fix it :-)<br><br>Attached you can find a diff output with the changes I made. Besides the Contact, I had to add more headers for compatibility reasons both to INVITE and REFER message.<br>
<br>I think a solution would be to add two params: "bridge_invite_hdrs" and "bridge_refer_hdrs", to manually include all the headers needed in initial INVITE and REFER (e.g.: modparam("dialog", "bridge_invite_hdrs", "Contact: <<a href="http://sip:click2dial@172.22.5.17:5060">sip:click2dial@172.22.5.17:5060</a>>\r\nSupported: 100rel\r\nContent-Type: application/sdp\r\n")). Perhaps these params could be a bit confusing and error-prone for new users, however they would be quite useful. <br>
<br>Comments are welcome. <br><br>Regards,<br>Anton<br><br><div class="gmail_quote">2010/7/1 Daniel-Constantin Mierla <span dir="ltr"><<a href="mailto:miconda@gmail.com">miconda@gmail.com</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

<br>
regarding the missing Contact header in the REFER message, it can be
solved by including some lines in /modules_k/dialog/dlg_ transfer.c. In
this file, the Contact of the initial INVITE generated with dlg_bridge
command can be easily changed as well.<br>

do you have a patch that you can send for adding the contact header?<br>
<br>
Cheers,<br>

The problem now is only in the processing of the ACK generated by the
TM module. When this ACK leaves the Kamailio server the branch value of
the topmost Via header is '0'.<br>
<br>
Below you can find the debug output where the ACK is generated and
routed by Kamailio. Any idea about where the error can be?<br>
<br>
thanks in advance,<br>
