Call forwarding is a feature usually managed on the client side of Lync. If call-forwarding options are enabled, users can forward phone calls to another number or to another contact. The Set-CsVoicePolicy
and Get-CsVoicePolicy
cmdlets enable the Lync administrator to centrally manage this feature.
Get-CsVoicePolicy | Where-Object {$_.AllowCallForwarding -eq $True}
Set-CsVoicePolicy UK-London-Local -Allowcallforwarding $false
It is possible to manage Lync Call Forwarding using the Secondary Extension Feature Activation Utility (SEFAUtil), which is part of the Lync Server 2013 resource kit tools (an explanation about deploying SEFAUtil is available on the Microsoft TechNet page at http://technet.microsoft.com/en-us/library/jj945659.aspx). Andrew Price outlined the process in a post Call Forwarding via SEFAUtil (http://lyncme.co.uk/microsoft-lync-server-2010/call-forwarding-via-sefautil/) on his blog.
