When non-Lync endpoints dial the meeting ID in the meeting invitation, the incoming call is acted on by the 
Dial by Lync Conference ID dial rule. This dial rule causes the RealPresence DMA system to search any 
configured and selected SIP peers for a matching Lync conference. If the conference ID isn’t resolved on a 
Lync server, the system continues to resolve the conference ID using the next dial rule in the list. If the 
conference ID is resolved on a Lync server, the hosting Lync server gives the RealPresence DMA system 
information about the conference in question. The RealPresence DMA system dynamically creates a VMR 
and starts a conference on a Lync-capable MCU, passing the Lync conference information to the MCU. The 
MCU builds a cascade link between the newly created conference and the conference hosted on the Lync 
AVMCU. Lync clients and non-Lync endpoints can now interact in the conference.
Automatic Contact Creation and Configuration
You can configure the RealPresence DMA system to create and manage a corresponding Polycom 
conference contact in Active Directory whenever users create a new VMR. The RealPresence DMA system 
communicates with the Lync server to ensure the new contact it is enabled for Lync functionality. This allows 
the system to publish presence updates to the conference contact; Lync clients display a status of Available, 
Busy, or Offline for the conference contact in the client’s contact list. 
Lync and non-Lync Endpoint Collaboration
Callers with Lync clients and non-Lync endpoints can join the same conference in several ways. See the 
Microsoft Lync documentation for more details on specific call flows.
● Users of Lync 2013 clients can select a Polycom conference contact in the contact list and drag it to 
an ongoing Lync 2013 conversation window, starting a video call.
● Users of Lync 2013 clients can start a Lync conference by selecting the 
 (Show Menu) icon and 
choosing Meet Now. After starting the conference, users can invite more attendees to the conference 
or drag a Polycom conference contact into the conversation window to add the participant.
● Users of Lync clients can right-click a Polycom conference contact in the contact list and choose Start 
a video call.
● Users of Lync clients and other endpoints can use a Microsoft Outlook meeting invitation to connect 
to a Lync conference. Non-Lync endpoints can dial the included conference ID, and Lync clients can 
click the “Join Lync Meeting” link included in the invitation.
Note: Lync client contact creation delay
When you manually or automatically create a VMR or group of VMRs, allow up to 10 minutes for the 
newly created conference contact(s) to appear in the Lync client contact list.
Note: Required permissions for Active Directory service account
If you are integrating the RealPresence DMA system with Lync 2013 and plan to use the 
automatic conference contact creation feature, note that the required Active Directory 
service account permissions have changed from previous releases. The service account 
should have full permissions to add, change, and delete entries in the OU where the 
conference contacts are stored, along with full administrative permissions for Lync 
administration to manipulate these contacts.
