Field 3: Headset microphone gain adjust
Adjusts the gain of headset microphones connected either directly to a 48-Key Feature Phone’s headset
jack or a headset box connected to a 24-Key Feature Phone. If the headset microphone gain is too high
(“hot”), the user may perceive an annoyingly loud sidetone or hissing when on a station-to-CO call. The
default level should provide a comfortable sidetone level and adequate transmit volume when used with
recommended headsets.
Range: 0–5. Default: 2. (See table, below.)
Entry Value Entry Value
5 +9dB 2 0dB (default)
4 +6dB 1 -3dB
3 +3dB 0 -6dB
Warning: Changing the headset microphone gain will drop all calls in progress. Before making any changes to
this parameter, make sure that all stations are idle.
Field 4: VIP text-messaging enable/disable
With this feature enabled, VIP Professional and VIP PC Attendant Console users can use VIP
to text-message.
Default: Enabled.
Field 5: System-wide HOLD key lamp appearance
With this feature enabled: when a station user presses the HOLD key, the HOLD LED flashes on all ESI
digital stations in the system when the call is placed on system-wide hold.
With this feature disabled: when a station user presses the HOLD key, the HOLD LED remains off on all
ESI digital stations in the system except the station that placed the call on system-wide hold.
Default: Enabled.
Field 6: Exclusive hold as default
If system-wide is selected: when a station user momentarily presses the HOLD key, the call is placed on
system-wide hold; pressing the HOLD key for an extended time period places the call on exclusive hold.
If exclusive is selected: when a station user momentarily presses the HOLD key, the call is placed on
exclusive hold.
Options: System-wide and exclusive. Default: System-wide.
