If your organization has enabled it, you can integrate Microsoft Lync 2010 communications software with your organization’s non-UC (unified communications) phone system.

We recommend using a phone that is UC-certified. You cannot make a video call between two different phone systems. For more information, see “Using a non-UC (unified communications) phone system.”

Remote call control URI (sip)  

Type the uniform resource identifier (URI) of the computer telephone integration server that manages telephone services for you. If you do not know the remote call control URI, contact your support team.


  • The URI is in the form of a Session Initiation Protocol (SIP) address. This remote call control URI will look similar to:

  • sip:+13165551465@SEATTLE-LCSCTI-02.corp.contoso.com

Phone URI (tel)  

Type the URI of the phone to be managed. If you do not know the phone URI, contact your support team.


  • There are several standard formats for telephone URIs. For more information, see “RFC: 3966 - The tel URI for Telephone Numbers,” which is available at http://www.rfc-editor.org/rfc/rfc3966.txt. The telephone URI will look something like this:

  • tel:+14255550146;ext=51459
