Hi,
sorry for my late reply.
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 :-)
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.
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:
<sip:click2dial@172.22.5.17:5060>\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.
Comments are welcome.
Regards,
Anton

Hi,
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.
do you have a patch that you can send for adding the contact header?
Cheers,
Daniel
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'.
Below you can find the debug output where the ACK is generated and routed
by Kamailio. Any idea about where the error can be?
thanks in advance,
regards
