The Viking VoIP SIP compliant classic style desk and wall mounted hotline phones are built with a multi-number dialer that rolls to the next number on busy signal or no answer. When the handset is lifted, the phone dials the first programmed number. If the call is not answered, the phone will dial up to three additional phone numbers. A ringer with adjustable volume and cadence can indicate an inbound call. Alternatively, the phone’s auto answer feature allows for silent monitoring of the location. Program the K-1900D-IP and K-1900D W-IP phones using software installed on a local PC or remotely using a static IP address. Firmware updates are downloaded automatically. Both desk and wall phones are available in two colors: red or ash. The matching handsets are hearing aid compatible and include a built-in volume control wheel.
