An independently-owned network
built for business


With decades of experience, we are an independent voice network carrying millions of minutes for organisations every year.

Our customers benefit from a highly resilient and diverse carrier class network. Each segment of our voice platform can operate in the event of hardware or interconnect outages by virtue of the design.

We peer and directly interconnect with most major carriers to minimise the points of failure and deliver calls in the fewest possible hops; reducing latency and guaranteeing exceptional call quality.  Some of our interconnects include LINX, IXManchester, Cogent, TATA, TalkTalk, BT, M247, UKFast, LDeX, OVH, Amazon AWS and many direct peers across IX exchanges.

We pride ourselves on the proactive monitoring that takes place across every piece of our network.  We have invested in cutting edge monitoring software, allowing us to monitor and manage CPE kit with visibility of VoIP calls, strengthening our Service Level Agreements and providing Quality of Service assurances to our customers.

“I would happily recommend Infinitel as they have provided Cloudbox with an excellent, resilient service with superb call quality in our UK and South African offices. ” Nick Goodenough - Cloudbox
