Enable the users for Enterprise Voice on premises

For a user to use Phone System in Office 365 (Cloud PBX), you must first enable them for Enterprise Voice and assign them a phone number. You do this using your on-premises deployment while the user is still homed in the on-premises deployment.

To enable a user for Enterprise Voice on premises and assign a phone number

  1. From a user account that is assigned to the CsUserAdministrator role or the CsAdministrator role, log on to any computer in your internal deployment.

  2. Use the Start menu or desktop shortcut to open the Skype for Business Server Control Panel.

    You can also open a browser window, and then enter the Administrator URL to open the Skype for Business Server Control Panel.

  3. In the left navigation bar, click Users.

  4. In the Search users box, type all or the first portion of the display name, first name, last name, Security Accounts Manager (SAM) account name, SIP address, or line Uniform Resource Identifier (URI) of the user account that you want to enable, and then click Find.

  5. In the table, click the Skype for Business Online user account that you want to enable for Enterprise Voice.

  6. On the Edit menu, click Show Details.

  7. Under Telephony, click Enterprise Voice.

  8. Click Line URI, and type a unique, normalized phone number (for example, tel:+14255550200). Then click Commit.

Special considerations when enabling users for Enterprise Voice on premises

In some cases, you may need to modify the way you enable users for Enterprise Voice to make sure that they can successfully make and receive calls. If you have users in your deployment that meet the following conditions, perform the steps included to enable the user for Enterprise Voice.

  • If a user is created in your on-premises AD and then synchronized with Skype for Business Online without being enabled for Skype for Business or for Enterprise Voice and do not have a LineURI set, run the following cmdlets for each affected user, replacing the values in < > with actual values for your environment:

    Enable-CsUser $username -HostingProvider sipfed.online.lync.com -SipAddress sip:<UserName>@<SIP Domain>
    
    Set-CsUser $username -EnterpriseVoiceEnabled $true -LineUri "tel:+<Telephone Number>"
    
  • If a user is already enabled for Skype for Business on premises, but was not enabled for Enterprise Voice or assigned a LineURI before being moved to Skype for Business Online, run the following cmdlet for each user:

    Set-CsUser $username -EnterpriseVoiceEnabled $true -LineUri "tel:+<Telephone Number>"
    
  • If a user is already enabled in Skype for Business on premises but not enabled for Enterprise Voice, even if already assigned a LineURI, run the following cmdlet for each affected user:

    Set-CsUser $username -EnterpriseVoiceEnabled $true
