Dialing by Extension
I'm having trouble finding an answer on this. I know this question has been asked before, but lots of things I'm seeing are pointing to Skype Business or users coming from Skype to Teams Phone, etc.....
- How many people are you talking about having extensions and numbers different than their DID?
You could create a number normalization rule that normalizes 4 digits to the full phone number, you'd just end up with 1 rule for each person that has a different DID/extension.
New-CsVoiceNormalizationRule -Name BobsExt -Description "Bob's Extension to DID" -Pattern '^1122$' -Translation '+15555555555;ext=1122'
New-CsVoiceNormalizationRule -Name SarahsExt -Description "Sarah's Extension to DID" -Pattern '^2211$' -Translation '+15555554242;ext=2211'
If you put the numbers in a spreadsheet/csv it wouldn't be hard to use some PowerShell to loop through the list and then push it into Teams.
Another option, though not sure if it's available yet, is Teams Private Numbers. Assign a static phone number with the extension as a private number, then your normalization rule is simplified:
New-CsVoiceNormalizationRule -Name ExtensionMatch -Description "Extension Normalization" -Pattern '^(\d{4})$' -Translation '+15555555555;ext=$1'

welcome to the Microsoft community, my name is Recep I'll be happy to help you today.
I understand that you are migrating from Zoom to Teams phone and now you want to be able to dial by extension.
Please note that the users you want to make available for Dial By Extension need to have an extension specified as part of one of the following phone attributes defined in Active Directory (and synchronized via Microsoft Entra Connect) or Microsoft Entra ID. For more information, see https://learn.microsoft.com/en-us/microsoft-365/admin/add-users/add-users.
- TelephoneNumber (AD and Microsoft Entra ID)
- HomePhone (AD)
- Mobile (AD and Microsoft Entra ID)
- OtherTelephone (AD)
The required format to enter the extension in the user phone number field can be one of the following formats:
+<phone number>;ext=<extension>
+<phone number>x<extension>
x<extension>
Example 1: Update-MgUser -UserId 'email address removed for privacy reasons' -MobilePhone '15555555678;ext=5678'
Example 2: Update-MgUser -UserId 'email address removed for privacy reasons' -MobilePhone '+15555555678x5678'
Example 3: Update-MgUser -UserId 'email address removed for privacy reasons' -MobilePhone 'x5678'
You can set the extension in the https://admin.microsoft.com/ or the https://aad.portal.azure.com/. It can take up to 12 hours before changes are available to Auto attendants and Call queues.
Note
If using the TelephoneNumber field to define the extension, Microsoft recommends that you use the format +<phone number>;ext=<extension>. If the user is also assigned a Teams Phone Number, you should define both numbers the same way.

To add to my last comment...
Looking in MS Entra portal for the user I added the phone number for. Under "Business phone" it shows the phoneNumber;extension I used in the Set-MsolUser command.
Did I do that correctly? And how will I know when the extension is ready to be tested?
Also, we have a handful of on-prem users that are synced to Azure AD. In this case for the synced users only, I would need to set the "Telephone number" field in the on-Prem AD, And that will write to the user in Azure...?
I'm really hoping a user will be able to just pickup their phone and dial a 4-digit extension to reach someone...
mmartin1935 Hey, for internal calls that don't through an auto-attendant, you could look at setting Normalization rules to use the last digits of a person's number as their 'extension' - assuming everyone has the same range of phone numbers.
This article has a good explanation of how to set it up - Use Extension Dialing in Microsoft Teams (ucstatus.com)
- HelloBenTeoh Thanks for the reply. Unfortunately the user's DID numbers and their extensions are completely unrelated... Since we're bringing in these extensions from our original Cisco phone system, then Zoom and now Teams. Some of the higher-ups still like to dial by extensions, which is why we're attempting to get this working.
I noticed in the normalization rules, when you choose advanced. You have the ability to use a REGEX. I'm guessing there's no way to somehow use a REGEX to match the "ext=xxxx" portion of the TelephoneNumber attribute?
So if that's not possible. Is the ONLY way you can direct dial an extension is if you can somehow match that to a portion of the user's full DID telephone number? Otherwise, it needs to be an Auto-Attendant?
Thanks Again,
