8.4. Enhancements for dcb_setbrdparm( )

8.4.1. Tone Clamping

NOTE:

The MSG_TONECLAMP parameter is supported and can be set to TONECLAMP_ON or TONECLAMP_OFF (default) by the dcb_setbrdparm( ) function. This parameter enables tone clamping to reduce the amount of DTMF tones heard in a conference. The DI products do not support tone clamping.

8.4.2. Changing the Interval for Active Talker Notification Events

Active Talker indications determine which conferees in any given conference are currently talking. Active Talkers are those conferees providing "non-silence" energy.

The MSG_ACTTALKERNOTIFYINTERVAL parameter can now be used to change the default firmware interval for Active Talker notification events. If necessary, an application can change the interval using this run-time board level parameter. The value must be passed in 100 ms units.
