Starting a meeting from a SIP/H.323 endpoint

You can start a meeting from an H.323 or SIP device by using your host key or pairing from the web. When a SIP/H.323 device starts a meeting using the host key, unlike other Zoom clients or Zoom Rooms only certain host functions are available:

Note: Even if joining using the host key or via pairing, they will still show as "Guest" to other participants in the meeting. Due to this, participants joining using other Zoom clients may see the notification "Host is not in the meeting yet", even though the device has joined as host.

Prerequisites for starting a meeting from a SIP/H.323 endpoint

How to include the Host Key in the Dial String

You can join a meeting as the host by including the host key in the dial string.

Note: Meeting passwords are modified to accommodate room systems that only allow numeric characters to be entered from their keypads. Passwords are changed to number strings when a meeting invite is created. This change only impacts the passwords required by room systems and not other devices.  


    Meetings without a password:

         [IP Address]##[Meeting ID]###[Host Key]

    Meetings with a password: 

      [IP Address]##[Meeting ID]#[Password]#[Layout]#[Host Key]


 Meetings without a password:

        [Meeting ID]...[Host Key]@[IP Address]
            Example: 123456789...123456@

     Meetings with a password:

        [Meeting ID].[Password]..[Host Key]@[IP Address]
            Example: 123456789.12345..123456@
