Hi all,
I have problem when use module pusher on Kazoo.
The user after receive call from pusher can not receive the Cancel message if have another people pick up this phone.
I trace log and debug on Kamailio and see the Freeswitch sent Cancel message but Kamailio reply 481 - Call leg/transaction does not exist.
The configure on Kamailio: default.cfg
=======================================================
route[PREPARE_INITIAL_REQUESTS]
{
if (is_method("CANCEL")) {
if(t_lookup_cancel()) xlog("L_INFO","$ci|log|======== t_lookup_cancel()");
xlog("L_INFO","$rm from $fu (IP:$si:$sp) ---CAPTURED IN MAIN---\n");
if (t_check_trans()) {
xlog("L_INFO","$rm from $fu (IP:$si:$sp) ---CHECK TRANS TRUE---\n");
//xlog("L_INFO", "$ci|log|====================================");
route(RELAY);
} else {
xlog("L_INFO","$rm from $fu (IP:$si:$sp) ---CHECK TRANS FALSE---\n");
sl_send_reply("481", "Call leg/transaction does not exist");
}
exit();
} else if (is_method("ACK")) {
if (t_check_trans()) {
route(RELAY);
}
exit();
}
=======================================================
Kamailio see the cancel message not same the transaction INVITE message.
