Teams common area phones are typically placed in an area like a lobby or another area that is available to many people to make a call: a reception area, lobby, or conference phone. Common area phones are signed in with accounts tied to a Microsoft Teams Shared Devices license which costs USD8.00 per month.
This article provides an overview of how to deploy and configure Teams phone devices as common area phones for shared spaces. Many of the Teams voice deployment steps were already covered in a previous blog post and here we will use the existing tenant dial plan and voice routing policy. Number assignment will be done using a new cmdlet that were introduced recently. Once complete the phone will be able to display a dialpad and make and receive PSTN calls via direct routing
In tthis walkthrough we created a new account in M365 admin center and assigned it with a Teams Shared Device license as shown below:
Next we use powershell cmdlets get-cstenantdialplan and grant-cstenantdialplan to obtain and assign the tenant dial plan to the newly created account as shown below:
We need to get the correct voice routing policy and assign it to the account. This is done using powershell cmdlets get-csonlinevoiceroutingpolicy and grant-csonlinevoiceroutingpolicy as shown below:
Next we use the new cmdlet set-csphonenumberassignment to assign the direct routing phone number (DID) from our SIP Trunk which also automatically enables the account for enterprise voice
Finally using the Teams IP Phone policy, we would normally set the SignInMode parameter to CommonAreaPhoneSignIn to enable the common area phone experience on the Teams phone device. This will disable the calendar and contacts on the phone but we can still enable directory search and hotdesking if so desired. This is done using the grant-csteamsipphonepolicy cmdlet as shown below:
