Debug NAT Issues

Posted:Wed 22 of Sep, 2010 (20:27 UTC)
Can you point me to a simple explanation of how SIP works through a router... and how I can figure out what is going wrong.
This worked fine on my old DSL router.
I just got a new actiontec GT704-WG wireless router and now any SIP client doing an outbound call through my Internet based asterisk box sounds great for exactly 10 seconds, then disconnects. Inbound calls work fine.
I would guess this is a NAT issue.
Thanks,
Don
