Overview
To avoid the Room Connector splash screen, you can enter the meeting details in the dial string on the SIP/H.323 device and join directly into the meeting.
Note: The meeting must be hosted by a Licensed user for an H.323 or SIP device to join. If the host's account does not have an available Room Connector license, but the attendee's does, you can use the attendee's Room Connector license.
