Viking Electronics K-1900-712L-IP VoIP Vandal Resistant Stainless Steel Panel Phone
Overview
The K-1900-712L-IP is a SIP-based VoIP panel phone built for high-risk, high-abuse environments — correctional facilities, psychiatric units, detention areas, and secure lobbies where standard handset phones are a ligature or vandalism liability. The 12-inch armored handset cable is the defining feature of this model: short enough to deny leverage for self-harm or equipment destruction, reinforced with an internal stainless steel lanyard that takes tensile load off the cable jacket itself. The front panel is 14-gauge 316 stainless steel with permanent laser-etched graphics — surface markings that won't peel, fade, or be scratched off. Auto-dial functionality triggers on handset lift, placing a call to a programmable 1–20 digit number without requiring the user to dial, which matters in environments where keypad interaction needs to be restricted or eliminated. A heavy-duty metal hook switch handles repeated forced use. Flush mounting is supported with the included rough-in box; surface mounting requires an optional VE-series box sold separately.
Compatibility
The K-1900-712L-IP connects to any SIP-compliant VoIP infrastructure — standard SIP PBX platforms, hosted SIP trunks, and VoIP gateways. It belongs to the Viking Electronics K-1900-7-IP Series, which shares the same SIP stack and mounting footprint. The included rough-in box targets new construction or drywall flush installation. Pairing with a VoIP intercom or panel phone system is straightforward via standard SIP registration. For surface-mount retrofit installations, the compatible VE-series enclosure from Viking Electronics provides the correct back-box depth and conduit knockouts. If your deployment requires access control integration — door release via relay — confirm relay output wiring against your controller's dry-contact input specs before install. Review your VoIP infrastructure SIP registration requirements to ensure extension provisioning aligns with the K-1900-7-IP Series dial plan.
Installation Notes
Flush mounting uses the included rough-in box; surface mounting requires the optional VE-series enclosure ordered separately — do not substitute a generic electrical box, as the VE-series provides the correct panel-to-wall depth for the stainless face plate. The 12-inch armored cable length is fixed on this model; if standard handset reach is required, select a different variant in the K-1900-7-IP Series without the cable restriction. The internal lanyard is pre-installed and is not field-serviceable — cable replacement should go through the manufacturer. Laser-etched graphics are permanent and cannot be customized post-manufacture; if custom labeling is needed, specify at order time through Viking's OEM program.
