Hello all. As they say in radio, “long time listener, first time caller”
Anyway, I am having trouble getting past the following road block and any help would be
greatly appreciated.
Kamailio version is 5.4.3
When attempting to use dispatcher to send OPTIONS packets to several TLS destinations, the
packets are leaving the Kamailio server on random ports. This is a problem because the
servers I am sending the OPTIONS to (MS Teams) are enforcing rport so the responses are
returned to a port that Kamailio is not listening on. I have tried to force the socket in
the event route (relevant parts of snippet below) but it does not appear to help. I
should also mention that I am not behind NAT and the TLS socket is specified in the
dispatcher attrs.
event_route[tm:local-request] {
sip_trace();
$fs = “tls:**ip-address**:5061”;
}
I have used Kamailio as a TLS server for many projects, but this is my first time as a
client. I am sure I am missing something.
