Quality we control.
We monitor and manage every stage of the call path on our own network, including at your busiest hours, so the people who run it look after your call quality.
Your calls travel on infrastructure we own, in seven data centres on five continents. Because we run it, one team answers for the quality of every call, day and night.

Owning the core network gives us something we can pass on to every customer: control. Here is what that control means for you.
We monitor and manage every stage of the call path on our own network, including at your busiest hours, so the people who run it look after your call quality.
Our engineers see the whole path, from your phone system to the far end of the call. One team looks after your service from end to end and supports you directly.
We write response and repair targets into your agreement because we control the infrastructure they depend on. If we miss a repair target, you receive service credits of one to five days’ monthly fee.
Your 3CX system is hosted directly on our network, and our SIP trunks connect through our own core. The 3CX virtual machines run on the same physical nodes as our SIP servers and supporting infrastructure, so your system and your calls share one path with one owner.
