Voip Unlimited

What Voip Unlimited does

Voip Unlimited is a UK-based, privately held telecoms carrier operating as VOIP-UN Limited (Companies House 05225497) from Poole, Dorset. Founded in 2006, the company is Ofcom-regulated as a Telecommunications Network Service Provider and holds ISO 27001 certification. Its core proposition is voice, connectivity, and unified-communications services delivered exclusively through UK channel partners — resellers, MSPs, and dealers — with no direct-to-end-user sales. The company owns and operates its own private voice and data network as a Tier-1 voice and Data ISP, with data centres in Poole and London and data processing confined to the UK and EU; a customer-contact office in Gozo, Malta supports EU engagement.

The product portfolio spans two UCaaS platforms (Voxone, launched December 2022 with a single-price per-user licence covering telephony, PBX, messaging, meetings and contact centre; and Voip Exchange, a cloud telephony platform starting at £8.50/user/month), a SIP trunking line-up (SIP Unlimited, SIP Lite, SIP Bundle Plus, Teams Trunk, IP Direct) with T.38 fax support, business connectivity services (SoGEA/FTTP broadband, leased lines, resilient Ethernet, Airwave rural wireless broadband, and validated Voice-over-Satellite via Starlink), security services (VU Guard DDoS mitigation, SIP anti-fraud auto-suspension), and a newer AI layer (AI Agent, launched July 2024, and AI Meeting, launched September 2025). Voxone Mobile, an eSIM-based Fixed Mobile Convergence product, was added in June 2025. The platform integrates with Microsoft Teams via Direct Routing, Microsoft 365, HubSpot, and Salesforce.

Revenue is generated through recurring monthly subscriptions (per-user UCaaS licences, channel-based SIP bundles in blocks from 10 to 200+ channels, monthly connectivity fees), usage-based pay-as-you-go tariffs on SIP services, revenue share with channel partners (a percentage of call profit plus monthly rental, plus white-label dealer commissions across all services), and a professional-services team handling complex bespoke deployments. The 2024 Comms National Award for Best Wholesale Service Provider was won in the up-to-£10M revenue category, and the company is also a multi-year connectivity provider to the Aston Martin Aramco Cognizant Formula One Team.

Broad incumbents

• Microsoft Teams Phone: Microsoft Teams Phone System is the platform-native voice/UCaaS offering within Microsoft Teams, integrated with Direct Routing partners including Voip Unlimited.

• RingCentral: RingCentral is a leading global cloud UCaaS provider offering cloud PBX, messaging, video, and contact centre as a unified platform. It competes directly in the UCaaS category where Voip Unlimited positions Voxone, though RingCentral operates at materially larger scale and broader geographic scope.
• 8x8: 8x8 is a global UCaaS and contact-centre-as-a-service provider serving mid-market and enterprise customers. It competes in the same cloud communications category as Voip Unlimited's Voxone platform, with broader product depth in contact centre.
• Vonage (Ericsson): Vonage is a global UCaaS and communications platform provider (now part of Ericsson) serving businesses of all sizes with SIP, UCaaS, and APIs. It is a much larger incumbent competing in the same SIP/UCaaS category as Voip Unlimited, including in the UK.
• BT Wholesale: BT Wholesale is the wholesale division of BT Group, supplying SIP, connectivity, and unified communications services to UK resellers and carriers. It is a Tier-1 incumbent that channel partners (including those Voip Unlimited serves) frequently compare against.

Direct peers

• VoIPfone: VoIPfone is a UK-based VoIP and cloud telephony provider serving SMBs and resellers with SIP trunking, hosted PBX, and connectivity. It is closely comparable to Voip Unlimited in scale, geography, product mix, and channel-focused positioning.
• Gamma Communications: Gamma is the largest UK-based wholesale ITSP and UCaaS provider, supplying SIP trunking, Horizon UCaaS, and connectivity to channel partners. It is the closest direct competitor to Voip Unlimited in the UK wholesale channel, with overlapping product portfolio and partner-led GTM.
• Sipgate: Sipgate is a UK- and Germany-based VoIP/SIP trunking provider serving SMBs and channel partners with similar pay-as-you-go and subscription SIP products. It competes in the same SMB-focused UK SIP market as Voip Unlimited.

Others

• Netgem (Netgem TV / Akcess): Netgem is a UK/Europe-focused connectivity and service-provider platform adjacent to wholesale telecoms. Included as an adjacent ecosystem player in the wholesale connectivity market that Voip Unlimited operates in, though its product focus differs (broadband/Wi-Fi vs UCaaS).
