Registration issue

[techdummy]

We are running 3cx v 15.5 SP6, and there is one extension that keeps registering back even though I have disabled the extension in the management console.
Has anyone encountered this issue?

Please let me know what can be done to keep it unregisterd, if you have.

Thank you.

Hello @techdummy

Please note that the "Disable Extension" option does not deny registration to IP phones. It removes the ability to call from the extension or calls to the extension. The exception is calls from that extension to emergency numbers.
To un-register the phone you need to either factory reset the phone or delete the extension.

hi techdummy,

if you just need to have it not register for a little while, but dont want to nuke the phone, you can change the password for the phone in the management console.

possible side effects:

- the IP address it's connecting from could be blacklisted , so whitelist it
- if you're connecting other devices (3cx app, other phones) they wont be able to register either

then you can just change it back when you're done and want it to register again
