Automatic gain control (AGC)

AGC is an algorithm for normalizing an input signal to a target level. The AGC

algorithm discriminates between voiced and unvoiced signals within a conference.

Active talker

The active talker feature sums the three most active talkers in a conference, so that

the conversation doesn’t get drowned out when too many people talk at once.

Conference monitoring

Participants have listen-only access to a conference.

Echo cancellation

This feature reduces echo from the incoming signal, improving the quality of a

conference for all participants.

Tariff tone

A party can receive a periodic tone for the duration of the conference call.
