Hi, Maksim!
There is nothing wrong with your configuration file, the problem is with
your traffic. It seems like your clients are sending REGISTER messages
with that have more than one TCP contact. OpenSIPS has only one TCP
connection to that client, therefore can only use one contact, but since
they are many, it does not know which one to use. That's why you see
that warning.
Is there any reason you clients are sending multiple contacts? Can you
fix that?
Best regards,
