v20 - Outbound DDI Caller ID reverting

[Bond21]

Hello,

Following on from the v18 to our own 3CX, one of the user extensions is reverting back the Outbound Caller ID after a set amount of time. I either remove the DDI entirely or put a new DDI in but the next day it is reverted back to a "+xxxxxxxxx" number. Is anyone able to assist please?

Thank you.

M365 Integration, Office Phone is set and is synced.

That's my guess.

Had a look on M365 and can see that DDI under that user! Have removed and will wait a bit but I think you've hit the nail on the head, thanks for the speedy reply!
