One number. Every device. One platform.

Gedema deploys SIP-based VoIP telephony — built on Yeastar — that unifies a development’s voice across reception, units, offices, the guard desk and mobile. Because it runs on the same IP network and speaks SIP like the intercom, voice becomes one more discipline we design, install and support in—house, not a separate contract with a separate provider.

Bring Us Your Project

Business telephony deep-dive

Enterprise voice, scaled to the development.

One partner. One contract. One accountable team never subcontracted.

+ Intercom

Both are SIP — answer the gate or door panel on the same desk phone or mobile app. No parallel system.

+ Networking

Voice rides the same managed network we build, on its own VLAN with QoS — so calls stay clear under load.

+ Security & KNX

Voice events can trigger or be triggered alongside access and automation — one accountable team across all of it.

The problem we solve

Why voice belongs with the rest.

THE OLD WAY

A separate telecoms supplier who doesn't own the network

Finger-pointing when call quality drops ('it's your WiFi')

Legacy line rental and rigid contracts

Voice bolted on after the walls are closed

WITH GEDEMA

One team that owns the network, the voice and the outcome.

Lower line costs and no per-handset vendor lock-in

Scales with the development, block by block, on one dial plan

Voice on its own VLAN, designed in from day one

SIP trunks & numbering

Keep existing numbers, add new ranges, and cut per-line rental — calls ride the internet connection, not legacy copper.

Desk phones & softphone

IP handsets at reception and offices, plus a mobile/desktop app — one extension that rings wherever the user is.

Auto-attendant & IVR

Greet and route callers automatically ‘press 1 for reception’ — no switchboard operator required.

Recording & reporting

Call recording, intelligent queues and live dashboards — for quality, compliance and staffing decisions.

Building Automation

Failover, remote branches and home workers on one platform — voice that stays up and spans borders.

Business telephony deep-dive

Enterprise voice, scaled to the development.

Each one is delivered, programmed and supported in-house and designed to talk to the other four.

Built for hospitality

Voice that behaves like a hotel guest expects.

Room-to-reception

In-room voice straight to the front desk, housekeeping and concierge — no third-party hotel phone vendor.

Wake-up & service codes

Automated wake-up calls, housekeeping status and minibar codes dialled from the room phone.

PMS-ready

Integrates with property-management systems so check-in/out, billing and room status stay in sync.
