Viking FXI-1A 

The FXI-1A will answer a ringing line, activate its relay, and pass the paging audio onto the amplifier. It will then drop the call based on Page Time Out, Silence Time Out, detecting a Busy Signal or Calling Party Control (CPC). See image below for further details.


Algo 8301 

The Algo 8301 is a SIP connection and an ATA is not required (nor will it work with the 8301). For information on 3rd Party Sip devices. On the Valcom V2003a switch SW3, set 4, 7 and 10 to the off position (up position). Also set SW2 to off position.On the 8301 web interface, go to Basic Settings -> Features and set the Line Out Analog Output Level to “-10dBm 600 ohm (0.245 Vrms)”. To play DTMF tones and control the zones, make sure to enable Generate In-Band DTMF Tones (Advanced Settings -> Advanced Audio).
