  2. In the drop-down that reads “IP address of E.164 number" either drop down the menu and locate the room that you desire or begin type the room number to provide an abbreviated list.  The drop-down is organized alphabetically first by Campus, then by Building Acronym, then by Room Number.
  3. SelectCall

The system will call out to the H.323/SIP room system selected which will join the meeting automatically.

For security reasons, H.323/SIP room systems are usually configured to be muted automatically when joining a meeting.  As such you will need to unmute the H.323/SIP room system using either the room control system or the remote control depending on the room.
