Thanks for your answer. Actually my ser.cfg is derived from a simple
onsip.org example. The weird thing is that I have an on-reply_route and
a t_on_reply("1") statement, and still I don't see the call coming in
the onreply-route logs (even when the 200 OK is sent). Maybe that
explains the problem.
I attached my config, is there any obvious problem there?
Thanks a lot for your kind help,
