In my case i need to change the header and then send it.
Here the case works if i make the changes after i sent the invite and got
the reply. As i know the t_on_branch will work after the invite is sent...
am i wrong?
There are many questions to ask about the branches... when do they work in
a serial manner, when parallel... where can i find it documented best?
Hi,
try the following:
route {
# Whatever you do in your main-route....
t_on_branch("modify_contact");
# Whatever you do in your main-route, the branch route is
automatically triggered for each branch.
t_relay();
}
branch_route[modify_contact] {
remove_hf("Contact");
append_hf("Contact: sip:whatever at
something<http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users>
\r\n");
}
failure_route[failure_from_np] {
# You need to modify the triggered branch_route again, otherwise the
same branch_route will triggered again...
}
Just calling "append_branch" does not help.
