01 / Capability · Connected Communication

E-PBX Systems

Business telephony platforms and endpoints — one call fabric across tenants, floors and sites.

IP telephony for enterprises, hotels and multi-tenant towers — one call fabric, many use cases.

Workplace interior where desk and software telephony share the building network

02 / The brief

A telephony platform is not a box on a wall. It is the fabric that carries calls, extensions, hunt groups, voicemail and inter-site connections for a business or a tenant community.

Zentrum designs IP telephony as part of the wider communication fabric — telephony, intercom, PA and in-building coverage worked out together rather than bought separately.

Part of Connected Communication.

03 / Signal and space

From source to the room itself.

Endpoint positions, cable drops, containment and the interfaces to intercom, PA and cellular coverage are all easier to resolve at design stage. The platform behaves best when the fabric below it — network, cabling, coverage — was planned to carry it.

  1. 01 /

    External communication

    Inbound and outbound calling delivered over the building's connectivity, arranged with the client's provider.

  2. 02 /

    Internal communication

    Extension-to-extension calling, door communication and announcements inside the property.

  3. 03 /

    Routing and control

    Call routing, groups, permissions and out-of-hours behaviour written against how the organisation works.

    Telephony, intercom and public address planned together rather than bought as three separate products.

  5. 05 /

    Endpoints

    Desk phones, softphones, door stations, handsets and speakers positioned where they are actually used.

  6. 06 /

    Coverage

    Reception across basements, cores, lifts and back-of-house so a call does not depend on where you stand.

Outcome /

One communication picture, not four.

Design and configuration only. Zentrum does not operate a network and makes no carrier claims.

Conceptual communication topology: external and internal communication meet a routing and control layer, which serves telephony, intercom and public-address systems, reaching endpoints across the property with coverage in cores, basements and back-of-house areas.

04 / Design principles

What makes the room work.

  • IP telephony platform

    E-PBX systems scaled for tenants, offices and mixed-use developments.

  • Endpoints

    Desk phones, DECT, softphones and mobile clients selected against how people actually work.

  • Dial plan and extensions

    Extension ranges, hunt groups, voicemail and routing designed against the business.

  • Interfaces and gateways

    SIP trunk and gateway configuration to connect the platform to the outside world.

  • Administration

    Administration and reporting that fit how the operating team already works.
