Voice Approved

When you upgrade your office internet for a faster, smoother connection, why not take advantage of cheaper, smarter phone calls too – by choosing a Voice Approved Circuit that provides full support for VOIP technology.

At Spitfire, we have a range of Voice Approved Circuits backed by SLAs that promise premium performance. No BT-based DSL circuits come with SLAs supporting ISDN voice quality – and without guarantees you run the risk of poor quality calls, call drops and intermittent/one-way audio.
