Zenitel IP devices supports Automatic Gain Control (AGC). The purpose of the AGC feature ..............

Default active???

Not config in TCIV+?

Log in to the Edge Controller, and navigate to Edge Controller > System Configuration > Call and Audio, and enable "AGC":

Enabling AGC in an IC-Edge system

Log in to the Zenitel IP device.

SIP mode: Navigate to SIP Configuration > Audio Settings, and enable "Automatic Gain Control (AGC)"
ICX-AlphaCom mode: Navigate to Advanced ICX-AlphaCom > Audio Settings, and enable "Automatic Gain Control (AGC)"

Some additional settings are available in Advanced Configuration mode. Navigate to Audio Settings > Audio signal processing:

Advanced AGC settings (screenshot from firmware 7 and later)

Enable AGC: AGC component brings the microphone signal to an appropriate range
AGC mode: Algorithm type
AGC gain profile: Extent level of added gain
AGC speed: Attack time

-*'''Enable AGC''': Check the box to enable automatic volume control. Volume is adjusted according to the ambient noise level. The AVC will perform better if the loudspeaker volume is set to a fairly low level, as this will give the AVC a more dynamic range for adjustments. Note that the AVC adjustment is disabled while the speaker is playing audio. Adjustments are made in silent periods (min. 100 ms silence required).
