Viking K-1900-812L-IP VoIP Vandal-Resistant Panel Phone 12in Cable

Viking Electronics K-1900-812L-IP VoIP Vandal-Resistant Panel Phone with Armored Handset Cable

Overview

The K-1900-812L-IP is a SIP 2.0 VoIP panel phone built for high-abuse environments — correctional facilities, jail vestibules, mental health units, and public access kiosks where a standard handset would be a liability. The 12-inch armored cable (31–33 cm) with an internal stainless steel lanyard is the defining spec here: it resists pulling and cutting attempts that would defeat a standard coiled cord, while keeping the handset physically constrained to the unit. Flush mount with the included rough-in box (5.0" × 10.0" × 5.53"), or surface mount with an optional VE-series box — both bring the 14-gauge 316 stainless steel faceplate flush against the wall with permanent laser-etched graphics that won't peel or fade under cleaning chemicals.

Power comes from a standard PoE Class 2 port (IEEE 802.3af, under 6.5W) — no separate power supply or homerun cabling needed, just a single Cat5e/Cat6 run to your PoE switch. The unit connects via a single RJ45 10/100 port, registers as a standard SIP 2.0 (RFC 3261) endpoint, and supports G.711u, G.711a, and G.722 audio codecs for wideband audio clarity on G.722-capable call servers.

Compatibility

The K-1900-812L-IP registers on any SIP 2.0 (RFC 3261) compliant call platform — tested use cases include Asterisk/FreePBX, 3CX, Cisco UCM, Avaya Aura, and cloud-hosted SIP trunks. The unit accepts a 26-bit Wiegand input, making it compatible with standard access control readers and panels (HID, AWID-format) for integrated door-release applications. Up to 1,000 keyless entry codes and 1,000 card numbers can be stored locally, reducing dependency on the call server for access decisions. The 14 gel-filled butt connectors support VoIP phone deployments in wet or outdoor environments where sealed terminations are required — relevant if paired with access control systems in exposed vestibules or parking structures.

For longer handset cord deployments, the K-1900-8-IP (34–37" cable) and K-1900-8-IP-EWP (52–57" cable, rated to IP66 for outdoor IP phone use) are sibling models in the same K-1900-8-IP series — same mounting footprint, same faceplate, different cable length and environmental rating. Choose this K-1900-812L-IP variant when cord-length minimization is the priority (suicide-risk environments, confined kiosk openings).

Installation Notes

Flush mount: install the rough-in box (included) during rough-in, then attach the 5.0" × 10.0" faceplate assembly at finish. Surface mount requires a separately purchased VE-series box. A single Cat5e or Cat6 run to an 802.3af PoE switch covers both power and data — no AC outlet required at the device. The unit operates from -40°F to 140°F (-40°C to 60°C) and handles 5–95% relative humidity (non-condensing standard; up to 100% with EWP sealing). FCC Part 15, CE, and Canada ICES-003 Class A compliance is documented — confirm your AHJ's requirements for correctional or institutional installations before rough-in. Wiegand wiring uses the 14 gel-filled butt connectors for field-sealed terminations; no punch-down block or separate terminal strip required.
