Configuring How the Conference is Opened

TSP providers typically wait for the WebEx host to call in before opening up an audio conference for the

meeting.

Until the host dials in (by entering the host access key) participants wait in a waiting room. If the host is late

or never dials in and unlocks the meeting from WebEx, the meeting never starts.

Contact your TSP provider to determine if they have a waiting room. If they do have a waiting room, there are

two methods for ensuring the conference is opened for a meeting:

Method 1: WebEx cloud services works with the TSP provider to include the host access key in the

DTMF dial string used by the MCU/TelePresence Server.

As soon as the first telepresence participant joins the meeting, the MCU/TelePresence Server dials the

string and joins as the host, unlocking the meeting.

Because the MCU/TelePresence Server dials in to the TSP on behalf of the host, the provider must

configure the audio conference to allow multiple hosts to log in. Otherwise, if a human host dials in after

the MCU/TelePresence Server dials in, the bridge is disconnected. The bridge then redials and the

human host is disconnected.

With multiple hosts, the human host still retains host privileges in the Cisco WebEx Meeting Center

application, and can mute or unmute participants or perform other host functions through the Meeting

Center if needed.

If the WebEx host enters the meeting before the first telepresence participant joins, participants hear the

DTMF dial string when the MCU/TelePresence Server attempts to start the meeting.

For situations where the host hangs up while the meeting is still underway, the audio conference may

terminate, depending on the TSP implementation and whether the hosts selects the option to keep the

meeting running in the Meeting Center application upon leaving.

Note: A DTMF dial string is required, whether or not you include the host access key in the string. Contact

WebEx cloud services for more information.

Method 2: The WebEx TSP server sends the W2A_UpdateConference=2 API command to the TSP

partner's bridge to unlock the meeting.

The TSP partner may have to recode their TSP adapter in order to recognize and properly execute the

unlock conference command.
