Hi All,
I have system setup where there are few Asterisk servers behind Kamailio. Everything is
working properly, the issue only is with the Incoming Subscribe's with to-tag from
endpoints.
Below you can see the invite:

Receiving such Invite Kamailio are routing to RELAY route (from WITHINDLG) and showing
such error:
ERROR: rr [loose.c:107]: find_first_route(): failed to parse Route HF
It seems that Kamailio cannot find such Dialog, but why is happening? where is it
destroyed?
How can i solve this?
Route (WITHINDLG) is as default, below you can see it as well.
-----------------------------------------------------------------------------------------------------------
route[WITHINDLG] {
if (!has_totag()) return;
if (loose_route()) {
if ( is_method("ACK") ) {
route(NATMANAGE);
}
route(RELAY);
} else {
if (is_method("SUBSCRIBE") && uri == myself) {
route(PRESENCE);
exit;
}
if ( is_method("ACK") ) {
if ( t_check_trans() ) {
t_relay();
exit;
} else {
exit;
}
}
sl_send_reply("404","Not here");
}
exit;
}

Thank You.
