I am getting the following error on opensips version 2.1.1. The scenario is
that I have a load balancer listening on TLS and it dispatches requests to
backend registrar servers listening on UDP.
90% of the calls are successful, but some calls fail and the load balancer
throws the following error when INVITE is being relayed to B party.

Any hints as to what might be going wrong?
