Enable the users for Enterprise Voice on premises

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
