Extension shows as registered, but phone says SIP register failed

[american10]

Hello. I have an issue with one extension where it shows green/registered, but the actual desk phone is show "SIP Register Failed."

I could probably just restart the entire PBX instance, but I'm curious if there is a way to unstick this extension registration without restarting the entire PBX.

It may have the mobile app registered and that would be why it shows green.

Hi @american10,

Is the phone local to the PBX, connected via SBC or STUN?

What type of phone is it?

What version of the PBX are you running?

I would power down the set, then power up, to force a registration, Then check the 3CX Activity log to see if there is a registration attempt, failed, or not, from that sets IP.

As mentioned above, there are other ways that the extension can be made green, while the phone remains unregistered independent of the above.
