Host Key Follow


The Host Key is provided for PSTN-only Personal Audio Conference (PAC) meetings and claiming host controls when joining a meeting by phone, an H.323 device, or the Zoom client when using Join Before Host.

In PAC meetings, it allows the meeting host (or other participant who knows the Host Key) to start a PAC meeting by entering the 6-digit pin when prompted by the Auto Attendant. After entering the Host Key on a PAC meeting, the meeting will start and others will be able to join as participants. The host of the meeting will have host controls available through DTMF, which are listed at Hosting a Personal Audio Conference meeting.

The host key can also be used by H.323/SIP systems connecting to meetings to claim the host role. Finally, it can also be used on the Zoom desktop application by selecting "Participants" and "Claim Host" to reclaim host controls when not signed in.
