Yes M365.Thanks for the reply. You can only define the fields mentioned above in AD to import to 3cx extensions. So what do you mean, give a user a DID, please? Which field under the extensions settings is one that you require? Please send me a screenshot of the field you wish to populate.
Additionally, you are referring to the AD import and not the M365 sync, correct?


Precisely.Thanks for the reply.
So to clarify this a little further, please, as it sounds like you would like to set up a DID in 365 and assign it to an extension through the 365 user sync and have the inbound rule created automatically so that the extension receives calls from it.
