[Asterisk-Users] sip change?

[Deon Rodden]

Whenever I see the "Maximum retries" message it usually indicated a 
communication problem, like one way traffic. Last time I got it, I 
traced it to a bad firewall rule, dropped the firewall and it worked, 
the time before that when I received it, it was due to a routing error, 
the server could get the request but couldn't respond (wrong gateway).
