Hello,
I've tried what you recommended, but without success so far.
This is the configuration block:
if (!has_totag()) return;
if (is_method("ACK")) {
dlg_manage();
}
if (loose_route()) {
if (is_method("BYE")) {
dlg_manage();
setflag(FLAG_ACC);
setflag(FLAG_ACCMISSED);
$dlg_var(billsec) = $DLG_lifetime;
}
route(RELAY);
exit;
};
if (is_method("ACK") ) {
if ( t_check_trans() ) {
route(RELAY);
exit;
} else {
sl_send_reply("606", "Not Acceptable");
exit;
}
}
Here is the sip trace:
https://pastebin.com/Aen2GCjm
And that's the error I'm getting in the Kamailio log file:
WARNING: dialog [dlg_handlers.c:1652]: dlg_ontimeout(): dlg timeout -
callid: ' 0555141d7d3hsag78sgce830391f9348 at 10.1.50.240:5060' tags:
'as52c10007' 'Uv7HS0jX65ctF' ostate: 3
Any other ideas?
