SIP/H.323 Room Connector Dial Strings

eTo 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.

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 attendees do, you can use the attendee's Room Connector license. 

Note: If you are joining a Zoom for Government meeting, please see our join instructions here.
