Viking Classic VoIP Desk Phone with Auto Dialer ASH Color - K-1900D-IP-ASH

Viking Electronics K-1900D-IP-ASH VoIP Desk Phone with Auto Dialer

The Viking Electronics K-1900D-IP-ASH is a hardened SIP VoIP desk phone built for environments where a single button lift needs to reliably reach someone — every time. Designed for kiosk installations, courtesy stations, and emergency communication points, this ash-colored unit auto-dials a 1–20 digit programmable number the moment the handset is lifted, removing any decision-making from the user. It draws under 4 watts on standard 802.3af PoE, so no local power supply is needed at the endpoint. If you're speccing a VoIP phone for a lobby, elevator bank, or secured entry that runs on an existing SIP infrastructure, the K-1900D-IP-ASH is worth a close look.

Key Features

• Auto-Dial on Handset Lift: Programs a 1–20 digit destination number that fires the moment a user picks up the handset — eliminates operator error at emergency or courtesy stations where users shouldn't have to know who to call.
• SIP 2.0 (RFC 3261) Compliance: Registers natively with any standards-compliant SIP PBX or hosted UCaaS platform. No proprietary gateway hardware required — wire it to your existing SIP phone system and provision like any other extension.
• PoE Class 1 Power Draw (<4W): Stays well inside 802.3af budget on virtually any managed or unmanaged PoE switch. A 48-port switch running 30W total budget can handle well over a dozen of these without strain. No local AC outlet, no power brick, no additional conduit run.
• G.722 Wideband Audio Codec: Supports G.711u, G.711a, and G.722 — the G.722 codec delivers HD voice (7kHz bandwidth vs. 3.4kHz on G.711) when both endpoints support it. Meaningful at noisy lobbies and entry points where speech intelligibility matters. Hearing-aid compatible amplified handset included.
• Rotary Handset Volume Control: Physical volume knob on the handset — no menu navigation, no touchscreen, no software setting. The user adjusts audio on the spot. Practical for shared-use courtesy phones in high-traffic areas.
• Wide Operating Temperature Range (-40°F to 140°F / -40°C to 60°C): Rated for environments most SIP phones can't survive — unheated equipment rooms, outdoor kiosks with shelter, cold storage anteroom stations. Not rated for direct weather exposure, but the thermal range covers most harsh-interior and semi-protected exterior deployments.
• 100BASE-Tx Ethernet (RJ-45, up to 100m / 328 ft): Standard Cat5e/Cat6 run up to 328 feet from the nearest PoE switch. No media converters, no fiber — a single cable handles both power and data for the full run. Integrates cleanly with 100BASE-Tx PoE network switches.
• PC-Programmable Configuration: The unit can be configured from any PC, making remote provisioning and bulk setup manageable without on-site button-pushing. Useful when deploying across multiple floors or buildings.
• Speed Dial Support (1–32 Digits): Supports programmable speed dial up to 32 digits — accommodates long-distance prefixes, extension strings, and feature codes in a single dial string without user involvement.
• Regulatory Compliance (FCC Part 15, CE, ICES-003 Class A): FCC Part 15 and CE marks confirm radio frequency emissions are within legal limits for commercial deployment in North America and the EU. ICES-003 Class A covers industrial/commercial environments specifically — appropriate for this product class.

Integration and Compatibility

The K-1900D-IP-ASH registers as a standard SIP 2.0 extension (RFC 3261) on any compliant IP PBX, hosted PBX, or UCaaS platform. Audio negotiation supports G.711u, G.711a, and G.722 — the far-end codec determines the actual audio path. The phone connects over a single RJ-45 10/100 Base-T port, powered by 802.3af PoE from the switch. There is no separate PC port or PoE passthrough, so plan the data drop accordingly if a local workstation also needs connectivity at the same point.

Both desk (K-1900D-IP) and wall-mount (K-1900W-IP) variants share the same SIP feature set and are available in ash or red. The red variant is used for high-visibility emergency station deployments; ash suits standard courtesy and kiosk installations. For environments requiring integration with access control systems or door intercom workflows, verify that your SIP controller supports auto-answer or DTMF relay on the receiving extension — the K-1900D-IP-ASH handles the outbound dial, but inbound call handling depends on the PBX configuration.

Frequently Asked Questions

Q: Does the K-1900D-IP-ASH require a separate power supply or AC outlet?

A: No. The K-1900D-IP-ASH is powered entirely by IEEE 802.3af PoE (Class 1, under 4 watts). A single Cat5e or Cat6 cable from a PoE-capable switch or injector provides both network connectivity and power. No local AC outlet or power adapter is needed.

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

A: The K-1900D-IP-ASH supports SIP 2.0 per RFC 3261, which is the industry-standard protocol used by virtually all IP PBX platforms (Cisco, Avaya, FreePBX, 3CX, and hosted UCaaS providers). Compatibility is determined by your PBX's SIP standard compliance, not a proprietary integration. Verify G.711 or G.722 codec support on your platform for best audio quality.

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

A: Yes. The auto-dial destination (1–20 digits) is programmable from any PC. You can update it without physical access to the handset, which is useful when call routing changes or the phone is reassigned to a different emergency contact.

Q: What is the operating temperature range of the K-1900D-IP-ASH?

A: The unit is rated for -40°F to 140°F (-40°C to 60°C) with humidity from 5% to 95% non-condensing. This covers most unheated equipment rooms, cold-storage anteroom stations, and semi-protected exterior kiosk applications.

Q: What is the difference between the K-1900D-IP-ASH and the K-1900W-IP?

A: The K-1900D-IP is the desk-mount form factor; the K-1900W-IP is the wall-mount variant. Both share the same SIP feature set, PoE power, audio codecs, and temperature ratings. Both are available in ash or red. Choose the desk version for countertop and tabletop kiosk deployments, and the wall-mount version for corridor or stairwell emergency stations.

Q: Is the K-1900D-IP-ASH hearing-aid compatible?

A: Yes. The K-1900D-IP-ASH includes an amplified handset with a rotary volume control and is hearing-aid compatible — relevant for ADA compliance considerations at publicly accessible courtesy or emergency stations.

Marty Allison

The K-1900D-IP-ASH (often searched as K 1900D IP ASH) earns its place in kiosk and emergency communication deployments specifically because of its -40°F to 140°F operating range paired with a sub-4W PoE Class 1 power profile — a combination that lets you drop this phone into thermally demanding locations without running a separate power circuit or worrying about the switch's per-port power budget.

Technical Highlights:

• PoE Class 1 (<4W): At under 4 watts, this phone consumes less than a third of what a standard 802.3af port delivers. On a 24-port switch with a 185W PoE budget, you could theoretically run 46 of these — the math matters when you're deploying courtesy phone banks in parking structures or transit facilities.
• G.722 Wideband Audio: G.722 extends voice frequency response to 7kHz versus G.711's 3.4kHz ceiling. In a noisy lobby or loading dock environment, that bandwidth difference is audible — callers can understand each other faster, which matters for emergency calls where you have one shot at conveying location information clearly.
• -40°F Cold-End Rating: Most SIP desk phones bottom out at 32°F or 41°F. The K-1900D-IP-ASH's -40°F floor puts it in the same thermal bracket as outdoor-rated intercom hardware, making it a legitimate option for cold-storage facility communication stations where typical office phones would fail by midwinter.

Deployment Considerations:

• The RJ-45 port supports 10/100 Base-T only — not gigabit. For dedicated phone drops this is irrelevant, but if your cabling plan assumed a shared data/voice port for a workstation and phone, you'll need a PoE-capable switch port per device or a midspan splitter approach.
• The auto-dial string supports 1–20 digits for the lift-to-dial function but the speed dial bank supports up to 32 digits — if your SIP trunk requires a feature access code or account code prefix, budget your digit count accordingly during provisioning.

This phone fits best in cold-chain warehouse courtesy stations, transit terminal kiosks, and secured facility emergency call points where the combination of wide thermal tolerance, amplified hearing-aid-compatible audio, and zero-training-required auto-dial eliminates both the equipment reliability and the user-interface problems in a single device.
