SIP Registration timeout / failure

[j_friedrich]

Hi guys,

Goin a little nuts here. Can anyone tell me why 'external' SIP phones / ATA's will STOP / LOSE their registration? Honestly, we have tried VPN hookups, direct hookups, you name it...For example, we have Cisco 186 ATA's out there and after a while (no specific time), they will lose their registration? We have the PBX on a static ip. Could it be that the ATA's / Phones need to be on a static ip too? I dunno, just frustrated that stuff goes 'offline' and we can't figure it out. It seems like the ATA's / phones just stop trying. There is nothing in the 3CX logs to indicate that they are trying to re-register. AARGGHHH...

Thanks for everyone's suggestions.

Jason

I have the same problem with my cisco wip 310 phone. The phone just logout . What should we do?

If 3cx doesn't see a registration every 30 minutes then it assumes that the ATA/set has been disconnected. Some devices allow the SIP server (3CX in this case) to set how often it will register. Some devices rely on the provision-er (you) to set that time manually. Change it to 30 minutes or less. See if that helps, there may be other issues as well.
