• Supports application convergence - business grade voice and internet services can be provided via one managed access connection when delivered over Ethernet

How does it work?

Switch Voice & Data simply connects a 'pipe' between your customer's site and our network, you just tell us what level of bandwidth is needed and when and where we need to connect to.

The service is also available over Ethernet, providing a complete IP access and SIP Trunking solution and is delivered as an end to end service with an availability guarantee, voice channel guarantees, and a guaranteed time to fix.
