3CX is a powerful, open-standards VoIP phone system and software PBX that rethinks traditional business telephone system pricing: instead of a separate licence for every user, you licence by simultaneous call volume, which can make 3CX particularly cost-effective where only a proportion of staff are on the phone at any one time. As a certified 3CX Titanium Partner, T2K Voice & Data (T2K VoIP) designs, installs and supports every type of 3CX phone system — from softphones, SIP desk phones and DECT handsets to live wallboards and virtual switchboard call handling — with CRM integration and contact centre capabilities, whether hosted in the cloud or deployed on-premise.
3CX offers unparalleled value and flexibility as a business VoIP telephone system. It's built for companies that want a full feature set — softphones, SIP desk phones, wallboards and switchboard-style call handling included — without being penalised by expensive per-user monthly subscriptions as they scale.
From basic call routing to advanced VoIP call centre operations, 3CX provides comprehensive VoIP and contact centre features — softphones, SIP handsets, wallboards, switchboard and more — managed through a single, intuitive web console, with capabilities varying by licence edition.
Because 3CX is a software-based VoIP PBX, you aren't forced into a single deployment model. As a 3CX Titanium Partner, T2K Voice & Data can build the system exactly where you want it — and we install, support and manage 3CX phone systems for businesses UK-wide, with dedicated local teams covering Bournemouth, Poole, Christchurch, Southampton, Portsmouth, Salisbury, Winchester, Weymouth, Dorchester and Totton across Dorset and Hampshire.
3CX licences are traditionally billed annually based on Simultaneous Calls (SimCalls) rather than per user. For most UK business deployments, T2K Voice & Data typically recommends the PRO or AI editions below, depending on the features and scale required — 3CX also offers separate entry-level and enterprise options for teams outside that range. Because every business's simultaneous call count, SIP trunk usage and support needs differ, T2K Voice & Data doesn't publish a fixed price list — every 3CX phone system quote is built around your actual requirements, bundled with secure UK SIP trunks and ongoing support.
Feature availability varies by licence edition and SimCall tier.
