35. Call LED Mode
The "Call" LED on the E-1600-IP Series can be programmed to one of four different modes. Factory Setting: Entry Phone
OFF Mode: Useful for silent monitoring applications. In this mode the LED will not light during normal operation. It will
only light (blink) if it cannot register with the programmed SIP server or while manually resetting all network parameters
to factory default.
Entry Phone Mode: The LED will remain ON in the idle state, turn off while button is pressed, blink during dialing,
light steady when the call is answered, then turn OFF momentarily when the call is completed.
Emergency Phone Mode: The LED will remain OFF in the idle state, blink during dialing, light steady when the call is
connected, then turn OFF when the call is completed.
Emergency Phone Outbound Only: On outbound calls, the LED will remain OFF in the idle state, blink during dialing,
light steady when the call is connected, then turn OFF when the call is completed. On in-bound calls, the LED will
remain off. This is useful for silent monitoring on inbound calls.
36. "Call" LED Control
During outbound SIP calls the "CALL" LED can be programmed to light automatically when the called party has
answered or only light after the called party has entered a touch tone "
37. Mute Current / Next Alarm
A network failure alarm will be indicated by providing 3 beeps every 30 seconds. A network failure indicates the unit is
not registered to the SIP server or there is a communication failure with the gateway. The three beeps can be muted
by clicking on "Mute Current / Next Alarm". The Status LED will continue to flash to assist troubleshooting. The alarm
beeps can also be permanently disabled. See Permanent Alarm Mute.
