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

Exeter is Devon's main business centre, with professional services in Southernhay and the city centre, science and data businesses at Exeter Science Park and Skypark near the airport, the Met Office and university, a large public sector, and trade, manufacturing and logistics at Marsh Barton and Sowton.

Solicitors, accountants and financial advisers in Southernhay need call recording and consistent caller ID. Science and tech firms want softphones, Microsoft Teams calling and integrations, so hybrid teams stay reachable on the same 01392 number.

Trade counters, manufacturers and distributors at Marsh Barton and Sowton need ring groups, rugged handsets and customer service queues. Moving off ISDN or analogue lines follows the same steps for all.

FAQ

Business Phone Systems & VoIP in Exeter — Frequently Asked Questions

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

Can I keep my Exeter 01392 phone numbers when switching to VoIP?
Yes. 01392 numbers can be ported to any of the six platforms we supply. We handle the paperwork with your current provider, and your existing line keeps working until the moment it switches over.
Do you provide on-site support for Exeter businesses?
Most Exeter phone systems are installed and supported remotely, and most faults are fixed over a remote session. Where a visit is genuinely needed, such as warehouse DECT or an on-premise PBX, we plan it with you and confirm it before you sign.
How much does a business phone system cost in Exeter?
Hosted platforms such as Gamma Horizon or 3CX typically cost around £10–£20 per user per month for a Exeter business with 5–50 users. Public bodies and larger organisations usually suit Mitel or 3CX on custom pricing, and every quote is itemised.
How long does a VoIP migration take for a Exeter business?
A single-site Exeter 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 a trade counter phone system handle busy mornings?
Yes. Call queues, hunt groups and overflow to mobiles mean customers get through even at peak times, and call reporting shows when you need more people on the phones.
Do Exeter businesses need to replace analogue and ISDN phone lines?
Yes. The UK's traditional PSTN and ISDN network is being retired by Openreach, including every exchange in Exeter and Devon. Any business still using analogue lines, ISDN2 or ISDN30 will need VoIP, SIP trunks or a digital line in their place. Check where your lines stand with our PSTN switch-off checker.
