Commonly the Contact provided by endpoints will be an unreachable IP 
address and port in this case. In order to reuse the already established 
connection you need to set contact_rewrite to yes. If the connection is 
established then it will be reused. If you restart and break the TCP 
connection then Asterisk won't be able to establish the TCP connection 
back and it is up to the endpoint to establish a new one.
