Aberdeen's Business Landscape & What It Needs from a Phone System

Aberdeen is often called the energy capital of Europe. Its economy is built around oil and gas, now shifting towards offshore wind and the energy transition, with supply-chain and engineering firms in Dyce, Altens, Westhill and around the harbour, plus professional services, life sciences and universities in the city.

Energy and engineering firms usually work across several sites and time zones, so they need multi-site calling, international numbers and calls that follow staff between the office, the quayside and travel. Many still run older PBX systems on ISDN that are due for replacement.

Marine and logistics businesses near the harbour need ring groups and out-of-hours routing for round-the-clock operations, while law firms and accountants in the West End need call recording and consistent caller ID.

FAQ

Business Phone Systems & VoIP in Aberdeen — Frequently Asked Questions

Questions we regularly hear from Aberdeen businesses comparing VoIP providers and phone systems.

Can I keep my Aberdeen 01224 phone numbers when switching to VoIP?
Yes. Any 01224 number can be ported to a VoIP phone system with no gap in service. T2K Voice & Data manages the porting for you, whichever platform you choose.
Do you provide on-site support for Aberdeen businesses?
Usually there's no need. We configure Aberdeen systems remotely and fix most faults the same way, which is quicker. Jobs such as a workshop DECT install or an on-premise PBX are the exception, and we agree those visits before you sign.
How much does a business phone system cost in Aberdeen?
For most Aberdeen SMEs with 5–50 users, hosted platforms such as Gamma Horizon or 3CX cost around £10–£20 per user per month. Energy firms and multi-site organisations usually suit Mitel or 3CX on custom pricing. Every quote is itemised, with no hidden fees.
How long does a VoIP migration take for a Aberdeen business?
A single-site Aberdeen business is typically live within a couple of weeks of sign-off. Larger rollouts across several sites usually take 4–8 weeks, and the switch itself happens out of hours.
Can we add international numbers for overseas offices and clients?
Yes. Hosted platforms can add numbers in many countries and route them straight into your Aberdeen system, so overseas clients call a local number and your team answers as normal.
Do Aberdeen businesses need to replace analogue and ISDN phone lines?
Yes. Openreach is retiring the UK's traditional PSTN and ISDN network, including every exchange in Aberdeen and Aberdeenshire, so businesses still on analogue lines, ISDN2 or ISDN30 need to move to VoIP, SIP trunks or a digital line replacement. Check where your lines stand with our PSTN switch-off checker.
