Priority Call Volume Control
Priority Call Volume Control is used to mark a keypanel as a priority caller. When a priority caller talks to another keypanel,
a minimum crosspoint volume (configurable in AZedit) is enforced for the duration of the call to ensure the caller is heard,
even if the target panel has set the listen volume to a lower volume.
In addition, a minimum volume of -6dB on the speaker and headset of the target panel is also enforced when receiving a call
from a priority caller (also ensuring the caller is heard, even when the target panel’s headset and speaker volume is turned
down. Once the call is completed, the previous speaker, headset, and crosspoint volumes are restored when the priority caller
stops calling.
When a panel is the target of a priority call, the speaker, headset, and volume display are shown with an orange background
indicating a priority call is in progress.
NOTE: The volumes are never lowered by the priority call, but are raised to the minimum values for the duration of the
call if they had lower values to begin with.
Available crosspoint values range from: +6dB, -80.0dB, and Mute.
By default, the priority call volume is set to +0.0dB .
