Using a DTMF keypad to control a conference
Host participants using telephones or SIP/H.323 endpoints that support DTMF can control aspects of a conference by using their keypad.
Default DTMF controls
The DTMF controls that can be used within a conference (Virtual Meeting Room or Virtual Auditorium) are:
| DTMF digits | Control |
|---|---|
| *7 | Toggle conference lock and unlock |
| *5 | Toggle mute and unmute all Guests |
| ## | Terminate the conference (disconnect all participants including yourself) |
Note that with calls made via the interoperability gateway, any DTMF signals are forwarded to the other party.
