/ The discipline, in detail
How we approach epabx & ip-pbx.
Voice infrastructure is rarely glamorous and never optional. We design extension plans, hunt groups, IVR menus, voicemail-to-email flows and PMS check-in/check-out triggers per the property's actual operating model. SIP trunks are sized to peak concurrent calls, not the brochure number. Hosted UC is offered where it lowers TCO; on-prem stays where data residency or call-volume economics warrant it.
In hospitality and healthcare the phone system is an operations tool, not a utility — check-in, room-status, nurse-call and emergency-line flows all run through it. We map the dial plan, hunt groups and PMS triggers to how the front desk and clinical teams actually work, then size SIP trunks and failover so a single circuit outage does not silence the building. Where a hosted platform lowers total cost we say so; where call volume or data residency favours on-prem we keep it there — and we document the migration path either way so the choice is reversible.
On record
Every epabx & ip-pbx engagement is documented end-to-end — design, programming, commissioning, calibration — and handed over with the files our successors would need if we were never to return.
/ Where we deploy this
Active across 4 sectors.
EPABX & IP-PBX is rarely a standalone brief — it sits inside a wider sector practice with its own codes, expectations and operating rhythm.
/ Sister services
The rest of it.
A serious brief usually crosses two or three of these. Read across the discipline — we deliver them as one contract.

Surveillance, fire detection, public-address, nurse-call, access-control, structured cabling and IP-PBX were engineered as one coordinated layer rather than seven discrete contracts.
/ Frequently asked
EPABX & IP-PBX — what buyers ask first.
On-prem PBX or cloud PBX in 2026?
Cloud PBX is the default for new deployments under 200 extensions; on-prem stays sensible above 500 extensions, in regulated sectors or with intermittent internet. Cloud is the default for new deployments under 200 extensions. On-prem stays sensible above 500 extensions, in regulated sectors with data-residency rules, or in properties with intermittent internet (where the call must continue through the outage).
EPABX or IP-PBX — which should we deploy?
IP-PBX is the right answer for any new install in 2026. SIP trunks have replaced ISDN for nearly all enterprises; the cost-per-extension is lower; integration with video conferencing, mobile clients and recording is built-in. We retain EPABX hardware only where existing extensions and analogue lines are too embedded to migrate.
How many extensions can a typical IP-PBX support?
Grandstream UCM630x supports 3,000 extensions and 450 concurrent calls — sufficient for most hospitals and hotels. Alcatel-Lucent OXO Connect scales similarly. Above that scale we deploy distributed clusters; below that scale we deploy a single appliance with redundant power.
Do IP phones need PoE switches?
Yes — modern IP phones (Grandstream, Alcatel, Yealink) all draw power from the network port. We design the network with sufficient PoE budget on day one — a typical 24-port PoE+ switch handles 24 phones plus 8 access points. Sizing for year-three growth is part of the design.
Can the PBX integrate with our CRM?
Yes — modern IP-PBX platforms expose APIs and SIP-based call-event hooks that integrate with Salesforce, HubSpot, Zoho CRM and most internal CRMs. Caller-ID lookup against the customer record, call logging and click-to-dial are standard features we configure on most enterprise deployments.
What's the lifecycle of an IP-PBX deployment?
Hardware lasts 7–10 years; firmware refresh cycle is 2–3 years. We track firmware and configuration baselines offline so a hardware refresh is a same-day cutover rather than a multi-week rebuild. End-of-life on a major version is signalled 18 months in advance through our AMC programme.
