Viking Classic VoIP Wall Phone with Auto Dialer Red Color - K-1900W-IP

Viking Electronics K-1900W-IP VoIP Wall Phone with Auto Dialer

The Viking Electronics K-1900W-IP is a hardened SIP wall phone built for controlled-access entry points, emergency call stations, and industrial facilities where you need a single-purpose device that dials a predetermined number the moment someone picks up the handset. Powered entirely over your existing Cat5e/Cat6 run via PoE Class 1 (under 4 watts), it requires no local power outlet — a practical advantage in stairwells, loading docks, and exterior kiosks where running line voltage is expensive or impractical. The K-1900W-IP (often searched as K 1900W IP) ships in red, making it immediately recognizable as an emergency or assistance phone without additional signage.

Overview

Wall-mount form factor measures 9.0" x 8.25" x 4.75" — large enough to be found quickly under stress, compact enough to fit standard backbox cutouts. The unit connects via a single RJ-45 jack to your IP network, registers as a standard SIP 2.0 (RFC 3261) endpoint, and auto-dials a 1–20 digit programmable number on handset lift. No keypad interaction required. This makes it well-suited for environments where you want callers to reach a specific destination — a security desk, dispatch center, or lobby receptionist — without giving them access to an open dial tone. Explore the broader Viking Electronics product line for companion entry panels, intercoms, and paging equipment that pair naturally with this unit.

Key Features

• Auto-Dial on Handset Lift: Programs a 1–20 digit number that dials automatically every time the handset is lifted — no buttons, no menus. Eliminates misdialed or unauthorized calls entirely, which is exactly the behavior you want at an unmanned emergency station or visitor check-in point.
• PoE Class 1 Power (Under 4W): Draws less than 4 watts from a standard IEEE 802.3af PoE switch port — the lowest power class, meaning it won't strain a budget PoE switch's power budget even with dozens of ports occupied. A single Cat5e/Cat6 run handles both data and power, simplifying installation in finished walls or conduit-constrained runs. Pair this with a managed PoE network switch if you're deploying multiple units across a facility.
• Hearing Aid Compatible Amplified Handset: The handset is hearing-aid compatible and includes a thumbwheel volume control — a requirement in public-access and ADA-conscious deployments. The over-6-foot coiled cord (1.8 m) gives enough reach for users who need to hold the handset at a comfortable distance.
• Wide Operating Temperature: -40°F to 140°F (-40°C to 60°C): This range covers unheated parking garages, outdoor kiosks in northern climates, and sun-exposed utility rooms. Most SIP phones are rated to 32°F or 41°F at the low end — this unit's -40°F floor is a genuine differentiator for cold-weather or uncontrolled environments. If you're deploying in VoIP phone applications where ambient temperature swings hard, this rating matters.
• Adjustable Ring Volume and Cadence: Ring volume and cadence are both adjustable — useful for high-noise environments like loading docks or machine floors where a default ring may be inaudible or where a distinctive cadence helps staff identify the source phone.
• SIP 2.0 RFC 3261 Compliance: Registers with any standards-compliant SIP PBX or hosted UCaaS platform. No proprietary protocol lock-in means you can integrate this phone into an existing Cisco Unified, Asterisk, FreePBX, or cloud-hosted SIP environment without special licensing or gateway hardware.
• Audio Codecs G.711u, G.711a, G.722: G.722 provides wideband (HD) audio — noticeably clearer voice quality compared to narrowband G.711 when your PBX and network support it. In noisy environments, cleaner audio reduces miscommunication at critical call stations. G.711u/a ensures fallback compatibility with legacy PBX infrastructure.
• 100BASE-Tx Ethernet (RJ-45): Standard Fast Ethernet connection. While it won't bottleneck a modern gigabit LAN, it's more than sufficient for voice traffic — a SIP call consumes under 100 Kbps even at G.722. No special switch configuration needed beyond a standard PoE port.
• Regulatory Compliance — CE, FCC Part 15, ICES-003 Class A: FCC Part 15 and ICES-003 Class A certifications confirm the unit meets commercial-grade emissions standards — relevant if you're deploying in environments with sensitive RF equipment or if procurement requires documented regulatory compliance.
• Red Color for Immediate Visual Identification: The red housing makes this unit visually distinct from standard office handsets without custom labeling. In emergency use cases — visitor assistance, panic stations, fire warden phones — color coding is a fast-identification aid that reduces response time.

Integration and Compatibility

The K-1900W-IP registers as a standard SIP 2.0 endpoint (RFC 3261) on any compliant IP-PBX or hosted SIP platform. Configuration is handled via the phone's built-in web interface or through provisioning files — no proprietary softphone or management server required. The unit connects at 100BASE-Tx over a single RJ-45 run and draws power from any IEEE 802.3af-compliant switch port. For facilities deploying multiple units — multi-floor stairwells, parking structures, campus emergency networks — each phone registers independently as a separate SIP extension. If your deployment requires a companion access control or entry system, Viking's panel phone and door controller product families use compatible SIP infrastructure and can share the same PBX dial plan.

Frequently Asked Questions

Q: Does the K-1900W-IP require a separate power supply?

A: No. The K-1900W-IP is powered entirely via IEEE 802.3af PoE (Class 1, under 4 watts) over the same Cat5e/Cat6 cable used for network connectivity. No local AC outlet is needed.

Q: What SIP platforms is the K-1900W-IP compatible with?

A: The K-1900W-IP complies with SIP 2.0 RFC 3261 and registers with any standards-compliant SIP PBX or hosted UCaaS platform — including Asterisk, FreePBX, Cisco Unified Communications Manager, and most cloud-hosted SIP providers. No proprietary protocol or gateway required.

Q: Can the auto-dial number be changed after installation?

A: Yes. The K-1900W-IP supports a programmable 1–20 digit auto-dial number. Programming is accessible via the phone's configuration interface and does not require a factory reset or physical access beyond normal network connectivity.

Q: Is the K-1900W-IP rated for outdoor or cold-weather installation?

A: The operating temperature range is -40°F to 140°F (-40°C to 60°C), which covers most unheated indoor environments and sheltered outdoor applications. For fully exposed outdoor deployment, verify whether additional weatherproof enclosure is appropriate for your specific climate and exposure conditions.

Q: What audio codecs does the K-1900W-IP support?

A: The K-1900W-IP supports G.711u, G.711a, and G.722. G.722 enables wideband (HD) audio when your PBX supports it; G.711u/a provides fallback compatibility with legacy infrastructure.

Q: What are the physical dimensions of the K-1900W-IP?

A: The K-1900W-IP measures 9.0" x 8.25" x 4.75" and ships at approximately 3.0 lbs (1.36 kg). The coiled handset cord is over 6 feet (1.8 m).

The K-1900W-IP is one of the few SIP wall phones I'd confidently spec into an unheated parking structure or cold-climate stairwell without a second thought — that -40°F floor isn't marketing copy, it's a real operational advantage over the standard 32°F-and-above consumer-grade SIP handsets that show up on most IT procurement lists. The auto-dial-on-lift behavior is the other anchor spec: one programmable number, no keypad, no option for misuse.

Technical Highlights:

• PoE Class 1 under 4W: Lowest PoE class — you can deploy these on a budget unmanaged PoE switch without worrying about per-port wattage caps. Useful in retrofit scenarios where the switch is already 60-70% loaded.
• G.722 Wideband Audio: If your PBX supports G.722, voice quality at a noisy loading dock or machine floor is meaningfully clearer than G.711 — less repetition, fewer misheard numbers during high-stress calls.
• SIP 2.0 RFC 3261 with No Proprietary Lock-In: Provisions as a standard SIP endpoint, which means your existing dial plan, call routing rules, and voicemail handling all apply without special configuration. No additional licensing from Viking to integrate.

Deployment Considerations:

• The 9.0" x 8.25" x 4.75" wall-mount footprint is larger than a standard intercom panel — verify backbox dimensions before rough-in, especially in finished wall retrofits with limited depth.
• The operating humidity spec tops out at 95% non-condensing — for truly wet locations (car washes, exterior-facing kiosks with direct weather exposure), plan for a sealed enclosure. The phone is not independently rated for direct water ingress.

This unit is the right call for campus emergency call stations, parking structure assistance phones, and controlled-access visitor entry points where a single dedicated number and instant connection on handset lift is the entire use case — not a general-purpose desk phone.
