Lync Room System (LRS) Configuration


For a long time, Lync did not have a proper “Conference Room” solution to carry out Video Conferences and Content shearing sessions. For those who familiar with solutions such as Crestron Room  Control systems,  the user would be the same. in fact, Crestron has introduced a Room solution called “Crestron RL” to support Lync Room System platform

The features of LRS includes,

  • One touch meeting joining experience. Initiate the meeting by touching meeting request on Room Control device
  • Content sharing and Switching
  • High resolution video

Let’s get on with the configuration. first of all, an Exchange Mailbox is needed. this has to be a room mailbox. Create the mailbox using EMS or EMC. i’ll be using EMS for this configuration.Capture1

Set the created mailbox to automatically process the requests. set the “AddOrganizerToSubject” as False and “RemovePrivateProperty” as FalseCapture2

Configure the Mail TIp. I’ve configured a sample message for this.Capture3

If the meeting request to be sent to remote LRS, then you need to add remote domains and enable Transport Neutral Encapsulation Format (TNEF).Capture4

Go to the AD and set a password for the newly created accountCapture5

When a Room Mailbox or a Resource Mailbox created in Exchange, it’ll get created as a disabled account. this account need to be enabled so that it can configure in Lync Server.Capture6

Log in to the Lync Server. go to the Lync Server management Shell and configure the Meeting Room with newly created accountCapture7

Enable Enterprise Voice to the meeting room account. enabling EV is optional but, if the EV is not enabled, meeting attendees won’t be able to dial PSTN and add users in to the meeting Capture9

Configure a Line URI for the for the meeting room Capture8

Set the Enable Room System AuthorizationCapture10

Create a custom conference policy for the meeting room and assign in to the room account. below is the recommended configuration for the conference policy
