VoIP & Unified Communications in Sabah

Last reviewed: 31 August 2026

VoIP and unified communications replaces legacy PABX phone hardware with IP-based telephony — call handling, extensions and voicemail run over the same network as everything else, and scale across branch offices without new hardware at every site.

The problem

Legacy PABX systems are expensive to expand, hard to find parts and support for, and don’t naturally connect multiple office locations onto one phone system. Every new branch means another isolated phone setup.

What’s included

  • IP phone system design and deployment
  • Handset selection and provisioning
  • Multi-branch extension and call routing setup
  • Voicemail, call recording and reporting where required
  • Integration with existing network infrastructure

How we deliver

Deployment starts with a call-flow assessment — how calls currently move between departments and branches — before designing the new system’s extension and routing structure.

Who this is for

Businesses replacing aging PABX systems, opening additional branches, or hospitality properties needing guest-room and back-office phone coverage on one system.

What it costs

Pricing depends on handset count, site count and the call-flow complexity involved, so it’s confirmed after the site assessment rather than listed here. Request a quote to get started.

Analog-to-SIP PBX migration for a Sabah cold-chain distributor

Migrated a Sabah cold-chain distribution company from an analog PBX to a Grandstream multiline SIP phone system, preserving every existing extension without disrupting daily operations.

Frequently asked questions

Do we need to replace all our phone hardware?

Not necessarily — depending on age and compatibility, some existing hardware can be reused. Confirmed during the site assessment.

Can this connect multiple branch offices on one phone system?

Yes, that's one of the main advantages over legacy PABX — branches can share extensions and call routing over IP.

What happens to calls if the internet goes down?

Failover options depend on the deployment — discussed during scoping, particularly for sites also running Starlink or SD-WAN failover.

Is this suitable for a hotel with guest room phones?

Yes — hospitality deployments are a common use case; see the Hospitality industry page.
