This is not a firewall issue as far as I can see. It happens to all devices
behind NAT and my router at home has no SIP enablement services.

Hello All, (this may be a double post, sorry if it is)
I have some questions regarding registration timers. I am running 4.2 behind
NAT and have noticed that the registration timer expiry for all my external
devices that are behind NAT (SPA2102's, 3102's, as well as Nortel 1535's,
LG6830's and my softphone) all have an expiration of under 300 seconds. If I
move the device to the local network the expiration timer is a more normal 3600
seconds.
I don't think this is a sipx issue.
make sure the firewall that you are using to NAT things isn't trying to be
smart and 'help you'.
review the information on remote users, and NAT.
sipx wants you to turn all SIP support off your firewall and let sipx do it.
