Solved Extensions on Yealink changing to DND on their own randomly

[JTR_RTJ]

Hello,

A number of extensions on Yealink changing to DND on their own randomly.
3CX Applications (Windows, IOS, Android) and Webclient not used for extensions.

Extensions are registered over a SBC to Yealink T42s and T46s phones, Phones are on the latest supported firmware?

Randomly the phones will switch to DND .
Switching to Available status is not possible, pressing the DND to desactivate it but return to DND in the second.

The extensions do not have auto switch set.

Tried resetting the phone , deleting and creating extension, still the same
Any ideas what could cause this?

Any help would be appreciated

Hello,

The're a couple of things you need to check

- Do you use Office 365 integration? The Status may change may be coming from there
- Do you use 3CX Phone for Windows? The allows autoswitching when the PC is idle

These extensions are not configured on Windows App.

An old O365 integration deactivated, but the old administrator did not disable calendar synchronization.
I will monitor the extensions status and post an update.

Thank you John .

No problem! Was it the Office 365 integration?
