After you configure Dual Tone Multiple Frequency (DTMF) conference control, you can perform conference control operations from the remote control of your endpoint.
Introduction
DTMF involves high and low frequency groups, each of which comprises four frequencies. A high frequency signal overlaps a low frequency signal to form a combined signal and represent a digit. The MCU supports number keys 2, 4, 6, 8 and arrow keys for DTMF conference control. The arrow keys can also be used for Far-End Camera Control (FECC).
If a conference is in discussion mode, you can use the arrow keys to perform DTMF conference control. The functions of the arrow keys are as follows:
- The left and right arrow keys are used to switch between participant videos in continuous presence pans.
- The up and down arrow keys are used to switch between the continuous presence modes for the local participant.
The arrow keys can be used for both DTMF conference control and camera control.
- If FECC is not supported, the arrow keys are used to control the camera by default.
- If FECC is supported, you can press Zoom and control the remote camera. If you do not perform any operations within 5 seconds, the functions of the arrow keys are switched to DTMF conference control.
The DTMF conference control functions of the number keys are as follows:
- Number keys 4 and 6 are used to switch between participant videos in continuous presence pans.
- Number keys 2 and 8 are used to switch between continuous presence modes for the local participant.
Procedure
- Configure FECC.
- Log in to the MCU using the CLI.
The default values of Login and Password are admin and Change_Me, respectively.
- At the <HUAWEI VP9650> prompt, enter system-view and press Enter.
- At the [HUAWEI VP9650] prompt, enter conf-policy and press Enter.
- At the [HUAWEI VP9650-Conf-Policy] prompt, enter conf-ctrl-by-FECC 1 and press Enter.
Returned message: Info:set enable FECC confctrl success!
- At the [HUAWEI VP9650-Conf-Policy] prompt, enter quit and press Enter.
- At the [HUAWEI VP9650] prompt, enter quit and press Enter.
- At the <HUAWEI VP9650> prompt, enter save and press Enter.
After are you sure to save config?(y/n), enter y and press Enter.
- Log in to the MCU using the CLI.
- Configure number key DTMF conference control.
By default, the MCU supports DTMF conference control using number keys, and no additional configuration is required.
Verifying the Result
Initiate a multipoint conference from the MCU. Using the remote control of a participant endpoint, press the number or arrow keys to check whether the endpoint can switch between continuous presence modes.
