[OpenSIPS-Users] Ipv6 on non-default port not working

[Robert Dyck]

Actually when I was testing I entered the listen parameters on the command 
line. I have now added them to the configuration file. The result is the same. 
The UA keeps sending the REGISTER request but there is no response from 
opensips. A UA on IPV4 can register on port 5062.

The configuration file I am using was taken from the rtpproxy modules examples. 
It was out of date so I had to add the UDP protocol and also change each 
instance of "break" to "exit".
