I prefer to keep my NAT Timeouts short ( ~5 minutes) and lets the
applications be responsible for keeping the connections open. **Most**
consumer grade routers use a timeout interval of 1 hour to 1 day. A
safe figure to start with is 600 seconds (10 minutes) and see if anyone
complains.<br>

Well, that did it. Your suggestion worked perfectly.
Does anyone know what a reasonable NAT Keep-Alive to use, if you don't
have access to their firewall/router configuration?
Thanks,

NAT, Registrations
Do you have STUN Enabled? I had similar when I had STUN turned on. I
found it better to turn off stun and place in sip.conf "nat=route".
Also use "NAT Keep-Alive" on the ATA that is < "NAT Timeout" on the Router.
Good Luck,

<pre wrap="">Hello,
We have several clients with GXP2000 in their network and behind NAT. We
have one particular client that has several GXP2000 behind a Linksys RV082
VPN Firewall/Router which is doing NAT services. According to SIP packet
inspection, it detects it's a symmetric NAT.
The problem we have is that even though we have configured Asterisk AND
the GXP2000 to register every 60 minutes, they keep unregistering and
re-registering every few couple of minutes (between 4 and 10 minutes).
We have checked the client's Internet connection and it's not bouncing as
well as their local network is working stable.
So, the only thing we can think of why these phones are re-registering so
often is their firewall device since it's the only "difference" between
this client and our other clients that use the GXP2000.
Does anyone have any idea why this is happening or how this can be resolved?
Thanks,
Daniel
