Just for the record..

My PAP2T that I use for my main line hasn't missed yet...registration is set for 1 hour.

My 502 that I have connected in tandem for my 2nd number and is pointed to the sip server, has been on all night and has not missed. Last reboot was almost 10 hours ago. Registration is still set for 1 minute. Firmware is still 1.0.1.21...no change

Both residing behind my router with no DMZ-no port forwarding-no nothing.
