Thanks Sergey! It works like a charm for BYEs.
Is it working for you on 200cancelling generated by Kamailio?
I tried the same work around with no success.
if (is_method("CANCEL")) {
if (t_check_trans()) {
if(!t_is_set("onreply_route"))
t_on_reply("MANAGE_REPLY_ON_CANCEL");
route(RELAY);
}
exit;
}
Thanks again,
Diego
