Business Phone Systems Portsmouth — Every Business, Every Platform

BT Openreach is switching off the traditional PSTN and ISDN telephone networks. Any Portsmouth or Hampshire business still using an ISDN line, analogue landline, or traditional PBX connected via ISDN will need to migrate to VoIP, SIP trunking, or a hosted phone system. We manage the entire migration — porting your existing numbers and ensuring zero disruption to your business communications.

Yes — in the vast majority of cases we can port your existing Portsmouth or Hampshire phone number to your new VoIP or hosted phone system. Number porting is a straightforward process and we manage it entirely on your behalf. Your customers dial the same number as always. There is no interruption to service during the porting process.

VoIP (Voice over IP) simply means making phone calls over the internet rather than traditional phone lines. Hosted PBX is a complete cloud-based phone exchange — your entire phone system is managed remotely in the cloud, with no on-site hardware. This is ideal for businesses that want enterprise features without the complexity of managing equipment. SIP trunking connects an existing on-site PBX to the internet, replacing ISDN lines at lower cost — you keep your existing desk phones and internal extensions. We advise on the right solution for your specific business size, budget, and requirements during your free survey.

Costs vary depending on the number of users, chosen platform, and whether additional cabling is required. Hosted and VoIP systems typically have lower upfront costs than traditional PBX hardware, with predictable monthly per-user pricing. SIP trunking replaces ISDN lines at significantly lower monthly cost. We offer completely free, no-obligation site surveys and written quotes.

We support both. We install new systems and we maintain, repair and expand existing systems across all major brands — including Panasonic, Avaya, Mitel, NEC, BT, 3CX, Yealink, Grandstream and more. If your current phone system is working well but needs an additional extension, a new feature, or a fault resolved, we can help without requiring a full replacement. We offer maintenance contracts and emergency callout for existing systems.

Yes — modern VoIP and hosted PBX systems include smartphone and laptop softphone apps as standard. Remote workers answer and make calls using their office extension number, appear in the company directory, and transfer calls to colleagues — exactly as if they were in the office. This is one of the biggest practical benefits of moving to a VoIP system and requires no additional hardware for most staff members.

Yes. While we are based in Portsmouth, we regularly work across Hampshire — including Fareham, Gosport, Waterlooville, Havant, Southampton, Chichester, and the wider region. For remotely managed systems such as hosted PBX and VoIP, location is essentially irrelevant — we can configure and support your phone system from anywhere. Contact us to discuss your location.
