you should wrap ds_next_dst() in an 'if' condition

Also, if you have more that 2 addresses in the destination group and
want to try all, re-arm the failure route
if(ds_next_dst()) {
append_branch();
t_on_failure("FAIL_ONE");
t_relay();

Hi All,
I'm still getting these errors and I'm struggling to resolve the
problem. I think I'm missing an append_branch or something simple in
my config, a little guiedance will be appriciated.
The error:
Nov 11 10:23:26 sip-router1 /usr/local/sbin/kamailio[23739]: ERROR: tm
[t_fwd.c:1379]: ERROR: t_forward_nonack: no branches for forwarding
Nov 11 10:23:26 sip-router1 /usr/local/sbin/kamailio[23739]: ERROR: tm
[tm.c:1300]: ERROR: w_t_relay_to: t_relay_to failed
The sip graph causing the error:

My config:

Do I need to have a mechanism to deal with a 486 form the carrier?
Thanks.
JR

1. One problem may be that you are calling route[RELAY] from your
failure route and using sl_send_reply(). The route[RELAY] is still
being invoked in a failure route execution context, even if you have
managed to contextually invoke another route, or subroutine if you will.
Stateless replies (sl_reply_error()) cannot be sent from within a
failure route.
2. Yes. throw an append_branch() into your failure route.

Well, that seemed to help greatly, so far no more errors after
changing my failure route to:
failure_route[FAIL_ONE] {
if (t_is_canceled()) {
exit;
}
ds_mark_dst("P");
ds_next_dst(); append_branch();
This is needed for version less or equal to 3.0.x if ds_append_branch
parameter is 0. Starting with 3.1.0 is no longer needed (if still used
is harmless).
Cheers,
Daniel

Thanks Alex, right on target again.
