Hi All,
I have a new FusionPBX installation running in a VM on Debian 13.
There are around 20 extensions configured, along with the same number of devices (Yealink SIP-T74U phones). Everything is working correctly except for one extension: 208.
This extension will not register any device. The same device can be assigned to a different extension and registers without any issues, but extension 208 will not register on any device. The phone simply shows “No Service”.
I have already tried the following:
No matter what I do, whenever I create extension 208, no device can register to it.
I had a similar issue with extension 202 a couple of weeks ago. At the time, I restored the VM from backup, which resolved it, but I did not have time to investigate the root cause. I would now like to understand what is causing this issue in case it happens again in the future.
Has anyone experienced something similar or knows what could be causing it?

I have already tried the following:
- Deleting and recreating the extension
- Registering the device with a different extension number first, then changing it back to 208
- Exporting/importing the extension configuration and modifying it manually
