Please note that in the example above, there are participants marked with a "star" icon. This means they are moderators or operators and cannot be moved to the waiting room.

# Send DTMF command

With TrueConf Room, you can send DTMF commands to DTMF-compatible devices in RTP EVENT (opens new window) and SIP INFO (opens new window) modes right from the conference control panel. To learn more about the transmission of such signals, please read the documentation provided by the manufacturer for each device.

There are two options to send DTMF commands:

# Option 1

  1. Open the Participants section by clicking on the corresponding button.

  2. Click the /docs/room/media/gui/more/en.png button next to the name of a participant and select Tone dialing.

# Option 2

  1. Open the Change layout section by clicking on the corresponding button.

  2. Click the video window of a participant to whom you want to send a DTMF command and select Tone dial.

To test DTMF signaling, you can use Public SIP URI of The Test Call (opens new window) website: #sip:thetestcall@getonsip.com. When DTMF commands have been sent, the robot reads out the digits you enter.

# Managing and changing participants’ audio and video devices
