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
Anton
