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:[EMAIL PROTECTED]:;>]+).*$/\1/");
avp_pushto("$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
