Applications — IP telephony systems by building type

Twenty-one scenarios across the building types we fit out: hotels and resorts, economy and chain hotels, hospitals, care homes, offices, apartment buildings, commercial buildings, warehouses, car parks, lifts and stairwells, schools, factories, and the platform integrations around them. Each one starts from the same question — what has to be reached, who answers, and what the cabling allows — and each is a reference design drawn from published capacity and product data.

  • Hotels, hospitals and care homes, offices, apartment and commercial buildings, warehouses, car parks, lifts, schools and factories
  • Twenty-one scenario pages, each with a quick answer, sizing by scale and at least two quantitative tables
  • Every page gives an area-by-area device plan and a configuration by scale
  • Sizing is stated in SIP trunks — 24 to 1000 across the OM range — because the manual does not state a maximum extension count
  • Cabling, PoE, power and network notes are included, along with 2-wire retrofit where buildings cannot be re-cabled
  • All plans are reference designs confirmed on the quotation; no customer, project or case study is named

OM series IP PBX wiring topology — the shared basis of the application reference designs

01

Hospitality

Guest rooms, front desk and service calls on one system — including the two-core retrofit for buildings that cannot be re-cabled.

2 entries

02

Healthcare

Ward call chains, nurse call, clinical intercom and care-home communications — sized by beds and call points rather than by desks.

4 entries

03

Offices & Buildings

Desk telephony and internal intercom for workplaces, from a single floor to a multi-site enterprise.

3 entries

04

Apartment & Entry

Entrance stations, indoor monitors and the door-release circuit — the part of a building every visitor touches first.

3 entries

05

Access & Safety

Communications where an outage is not an option: car parks, lift cars and stairwells, with the wiring and power rules that apply.

2 entries

06

Education & Industry

Campus paging and emergency calls, plus warehouse and factory announcement systems where background noise sets the design.

3 entries

07

Systems & Networks

The pieces underneath every scenario: the IP PBX core, SIP speakers, analog gateways and two-core converters.

How to use these pages

  • Start with the building type that matches the site, not with a product.
  • Use the device plan to walk the building area by area — entrance, room, corridor, desk, plant room.
  • Use the configuration by scale as the first sizing pass, then send us the counts for a confirmed model.
  • Read the cabling notes before a site survey: they decide whether the job is IP, hybrid or a two-core retrofit.

Where the source materials do not state a figure, the pages say so rather than estimating.

What every design shares

Every application on this site is built from the same components: an OM series IP PBX as the call-routing core, terminals that register over standard SIP, and gateways where the building still has analog lines, analog paging or two-core cable.

  • SIP terminals register as extensions, with extension numbering starting at 200 on the PBX.
  • Outside lines arrive as SIP trunks or on FXO analog ports, with PSTN failover available on outbound SIP calls.
  • Recording runs in G.711 and G.729 — locally on the OM20G and OM50G, remotely on the larger models.
  • PoE carries power and data to most terminals; the models without PoE or Wi-Fi use their stated supply.
  • ONVIF, Wiegand and RS485 appear only on the terminals the materials document them on.

Frequently asked questions

Are these real customer projects?

No. Every plan on these pages is a reference design built from the published capacity and product facts in our documentation, including the two sized care deployments printed in the manufacturer material. No customer or project is named.

Why is capacity quoted in SIP trunks rather than extensions?

Because the product manual does not state a maximum number of IP extensions for any model in the OM range. Published capacity is in SIP trunks — 24, 62, 216, 496 and 1000 across the five models — with up to 120 concurrent calls per trunk on the analog models and 200 on the OM1000-UC.

Can a design be adjusted to our building?

Yes. Send us the area counts (rooms, desks, wards, zones), the outside lines you hold and the state of the cabling, and the model, port mix and endpoint list are confirmed on the quotation.
