The significant growth of global voice traffic today – and how we’re supporting it

In the past few months voice traffic has grown exponentially. As workplaces have moved to remote operations Colt is witnessing significant increases in call volumes in regions where Coronavirus is having the greatest impact.

With more people than ever working from home, there has been an increase in mobile traffic initiated from networks to be terminated onto Direct Dial Ins or conference bridges.

As a result, these interconnects between fixed and mobile networks are the pinch points on the network. To put this into perspective, traffic has increased by more than 86% at peak usage, with a daily peak of 28 Gbps, placing pressure on session border controllers (SBCs) in terms of simultaneous call utilisation and geo-redundancy.

Built on the backbone of the Colt IQ Network, Colt already had a resilient voice network. However, we have invested significantly and scaled it to manage the current increase in voice traffic.

We are also managing the flow of voice traffic, ensuring the interconnect of calls via Colt’s network from mobile, Unified Communication (UC) and conferencing operators. As these tremendous waves of traffic continue to move in and out, we’re reacting accordingly and in a strong position to ensure the network is not overwhelmed.

There will come a point when global voice traffic settles down – in fact we have already seen traffic from regions with the largest requirements stabilise, such as Japan and even in Italy where levels remain high but stable.

Until then, fixed and mobile operators and enterprises need network providers that can upgrade and scale to accommodate the additional capacity requirements of this period.

We’re doing everything we can to enable our customers during this period. We’ve already added capacity and found solutions to pinch points, but we’re continuing to measure, control and optimise the flow of voice traffic across our network to maintain a reliable business-grade service for our customers.
