This is a re-send. I apologize if it is a duplicate. I suspect my subscription 
was not enabled.


I have been doing some testing with opensips 2.2.2 using ipv6. I found that 
the server will only respond to a request over IPV6 if it is configured to 
listen on the default port.

Wireshark sees a request addressed to the server but there is no reply.

Running opensips in the foreground show no activity associated with a request.

Netstat however shows the listening port. ( UDP 5062 )

Tried with global address and ULA.

IPv4 works with non-default port.
