Virgin Media Business SIP Trunking review
A high-capacity SIP trunking service for organisations retaining on-premises PBX systems.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Virgin Media Business SIP Trunking connects an existing business PBX to the provider’s network over an IP connection. It supports inbound and outbound voice calling, configurable call diverts, number porting, emergency calling, and encrypted signaling. The service is aimed at organisations retaining on-premises telephony while moving away from traditional analogue or ISDN connectivity. Connectivity can use Virgin Media Business options or another IP network, subject to compatibility and service requirements.
The pricing model combines monthly channel rental with call tariffs or inclusive-minute bundles, making it a hybrid arrangement rather than a simple flat subscription. Pricing is handled through sales, so organisations will need a tailored commercial discussion. The service fits infrastructure-led deployments through support for PBX and Session Border Controller connectivity, along with IPVPN and Dedicated Internet Access. This makes it more relevant to businesses planning around existing voice infrastructure than to teams seeking a standalone cloud phone system or broad application marketplace.
Capacity and operational controls are the strongest reasons to consider it. SIP channels can scale dynamically, with support for up to 5,000 channels, while priority and round-robin inbound routing help distribute calls. Administrators can configure business continuity plans, call diverts, and inbound and outbound statistics and usage reports through a portal. Organisations with large or growing PBX estates should consider it; smaller teams wanting simple self-service pricing, app-focused integrations, or a phone system without existing telephony infrastructure should look elsewhere.
