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. Just wondering if there is an issue with my system or is this by design? _________________________________________ It is by design. Some NATs won't let the external phone send packets to sipXecs unless sipXecs "keeps the NAT pinhole alive" by sending packets frequently. sipXecs forces this to happen by requiring external phones to re-register frequently (and thus, sipXecs sends responses to the REGISTERs frequently). Robert Joly can explain this in more detail, but he's on vacation.
