Configuration:

To configure the relay, select SIP Configuration > Relay Settings, and select which events should turn the relay ON and OFF.

Example: The relay goes ON when there is an incoming call, and OFF when the ringing stops

External loudspeaker (optional)

Connection of external 8 ohm loudspeaker

If ringing signal and group calls are to be received, an external 8 ohm loudspeaker must be connected. The loudspeaker is connected to pin 1 and 2 (LS) on connector P3. The external loudspeaker will be muted when the handset is lifted.

Note: The internal ringer device is not in use. The reason is that the housing of the IP telephones are also used in analog versions of the telephone, connected to regular 2-wire telephones lines. Then the ringer is operated by the ringing voltage from the telephone exchange. Although the ringer device is not in use in the IP Heavy Duty station, it has not been removed as it would jeopardize the IP rating of the station.
