Hi Zahid,
To be honest, I do not see the purpose of this:
# get last URI from destination-set and set it as R-URI
avp_delete("$avp(s:tmp)/g");
$avp(s:tmp) = $ds;
avp_subst("$avp(s:tmp)", "/.*(sip:.+@[^:;>]+).*$/\1/");
avp_pushto("$ru", "$avp(s:tmp)");
This code fetches the first branch (by using the $ds pv and the regexp)
and push it as RURI; but if there is no following append_branch(), it
has 0 effect. And if it does append_branch somewhere later, it will just
duplicate a branch....
Maybe Andreas (here CCed) can give you some details on this.....
Regards,
Bogdan

Hi,
If get_redirect() is already pushing the contacts as branches,
then what is the purpose / benefit / drawback of doing something like
this:
taken from sipwise online config:
if(!get_redirects("1:1"))
{
xlog("L_ERROR", "Failed to fetch contact '$ct' from
301/302 - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n");
acc_db_request("480", "acc");
t_reply("480", "Temporarily Unavailable");
exit;
}
# get last URI from destination-set and set it as R-URI
avp_delete("$avp(s:tmp)/g");
$avp(s:tmp) = $ds;
avp_subst("$avp(s:tmp)", "/.*(sip:.+@[^:;>]+).*$/\1/");
avp_pushto("$ru", "$avp(s:tmp)");
I'd greatly appreciate your answers as they will help me better
understand the use of branches/destination set.
Thanks.
