Extension dialling on Teams Phone doesn't work on Auto Attendant and won't transfer to the user
We are looking to switch to Teams Phone but we need to maintain our 4 digit extensions for the time being. I'm having a weird issue though where I can never get it to transfer to any user from the a...
- I figured this out in case anyone else has this issue. +14083030000;ext=0000 is not the correct format for me at least the Microsoft documentation says put the number ;ext= extension but the correct format to make it work for us was:
+14083030000x0000
I had been trying for weeks using the ;ext= format and it never works. As soon as I used x instead, it immediately worked for all users. I could even set it in AzureAD without using Power Shell.
I'm using Calling Plan and Operator Connect on 2 different tenants and using the format about with x was the only way for us to get either tenant to work.
If using on-prem AD and this syncs to AD Connect, where do I store the phone number with the extension? I see one reply that they added this to the M365 Admin Center. Do I need to add this to the on-prem AD as well?
thanks!!
To keep it uniform, Make the change within user account's properties from on-premise active directory and it will eventually sync to M365/Intra. Once the change is replicated, run the teams cmdlet to assign the same extension number within teams PowerShell module. Example (Set-CsPhoneNumberAssignment -Identity email address removed for privacy reasons -PhoneNumber "+14255551000;ext=1234" -PhoneNumberType DirectRouting). Note: By running this cmdlet, this feature will still work only from within auto attendants.
