120-room hotel — reference configuration

A room-by-room list for a 120-room property: 120 guest-room phones with service keys already named for wake-up calls, 60 bathroom positions, 24 staff extensions, and a PBX sized for 204 extensions with the analog ports a hotel always finds a use for.

Guest rooms: 120 × H6W with five named service keys, including wake-up call service
Bathroom and second positions: 60 × H2U with ten speed-dial keys
Staff and back office: 24 extensions — 10 desk phones, 2 front-desk consoles, 12 portable handsets
PBX: OM200G — 496 SIP trunks, four card slots, one 12FXS + 12FXO card with four FXO lines wired
Wake-up calls and room status to the property PMS are PBX functions, with no extra box
A reference design built from published capacities — not a named installation

What goes in the room, and how many — what should you know?

The room phone is the guest-facing part of the system, so the service keys are the specification that matters most. The rest of the count follows from the room mix.

The H6W and H2U take power over the network cable, so no local power supply is needed at the bedside
H6W AP mode lets the phone act as a router for the room — the brochure presents this as reducing cost and simplifying setup
H6W carries one USB-A port for charging a guest phone
Both room phones support G.722 and Opus wideband audio

Wake-up calls, room status and the PMS link — what should you know?

Wake-up calls are a system feature of the OM series, and the voice-prompt set includes a file named wakeup
Room status is set from a room extension with a feature code, and the PBX pushes it to the hotel PMS over the API
The hotel management docking module is the stated integration for room status and call-permission control
The auto attendant switches between working-hours and off-hours greetings, with up to three periods a day, so the night greeting needs no manual change
Call detail records can be pushed to an external server (default port 1809) for the property’s own call accounting

The materials do not describe the front-office screens behind these functions, so the exact wake-up and room-status workflow is confirmed on the quotation.

Trunks, escape routes and the card strategy — what should you know?

204 extensions sit well inside the OM200G’s 496 SIP trunks, which is the point of choosing this model over the OM80E: a hotel adds service extensions — lifts, alarm lines, a spa desk — for years after handover.

Each SIP trunk supports up to 120 concurrent calls
Four analog lines wired to FXO ports can take over when a SIP call times out or returns 4xx/5xx/6xx
ETH2 can be set as a redundant port and takes over from ETH1 in about 1.75 seconds
Cards are hot-swappable, so a failed card is replaced without taking the property down
Recording on this model is remote only, and dual hot standby is not available — only the OM1000-UC pairs two units

Frequently asked questions

Can the hotel keep analog handsets in the rooms?

Not in one chassis at this size. A 120-room analog plan needs 120 analog ports, and the OM200G reaches 96 across its four card slots, so a fully analog property would need more than one PBX chassis. In this design the room phones are SIP and the analog ports carry back-of-house devices and the escape route. Send us the room list and we will split the property or size a second chassis if analog room handsets are a requirement.

How are wake-up calls delivered?

Wake-up calls are a system feature of the OM series and the prompt set includes a file named wakeup. The hotel management module is the stated integration for wake-up calls and call-permission control, so the property’s own front-office system drives them. We confirm the exact workflow against the current firmware on the quotation.

Does one phone per room mean 120 extensions?

In this design each room phone and each bathroom phone registers with its own extension, so the room side is 180 extensions. If the property prefers fewer, the H6W’s Hotspot function lets several phones share one number from the server while each phone keeps its own extension number.

What keeps calls running when the network drops?

Three things in this design: the analog lines on the FXO ports, the ETH2 redundant port that takes over in about 1.75 seconds, and the backup SIP server mode, which can be set to a fixed address or to DNS SRV. Power backup for the equipment room is a site decision and is not part of this equipment list.
