[Asterisk-Users] SIP registration issues

[Martin]

Hello.

Is there any know issue with Asterisk 1.0.9 concerning intermittent SIP 
registration issues.

My SIP hard phone (aastra 9133i)  and soft phone (xlite)  keep losing 
registration so calls to them go direct to VM although calling to other 
phones from them works fine.  

The logs show  'Transmitting (no NAT):
SIP/2.0 403 Forbidden'  which doesn't occur when they miraculously start 
working/registering.

Asterisk seems to lose the user.

But then, some period of time later, they will start working at random times 
with no changes.
