Hi all,
So for a while now I've been working with our engineering team to troubleshoot these random events where the UPDATE message sent from the server never made it to the client side. Here is the the topology:
Server -(tcp)-> kamailio -(tls)-> client
So looks pretty straight forward and I have logging messages stating t_relay() was successful in sending the message.
The question is how do we know t_relay really successfully sent it? Does it actually monitor the physical interface as it goes out?
t_relay() may return successful code if the message was put in the writing queue. Later can be another log message if sending ended int a transmission timeout. Do you have a failure_route set for such t_relay()? If not, you can add one, it should be executed if sending fails.
