[SR-Users] branches usage

[Carsten Bock]

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\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.

Carsten
