CORE NETWORK

We Built Our Network A Bit Differently…

Developing the global backbone infrastructure to deliver uniformly high quality and resilient voice in 60+ of the world's highest-value countries is an undertaking that's been years in the making.

What Does the Voxbone Network Look Like?

Not like other voice networks, that’s for sure. We have 15 years’ experience in assessing the best ways to deliver smooth, reliable and consistent service into a disparate range of countries, spread across four continents and with wildly varying regulatory landscapes.

In that time, we’ve been able to build a global network footprint that’s designed to support your business the right way, regardless of your location. What that means is a fully meshed, redundant, MPLS network built on our own code base and around the principle of two core Points-of-Presence per region, with real-time auto failover mechanisms in place.

The strength of our network lies in thephysical locationsof our core infrastructure

 

We’ve carefully selected the locations of these SuperPoPs to provide the lowest possible latency across each major region where we operate. The result is consistent telecoms on a global scale, withsub-200ms latencyto anywhere on earth. And we’ve paired them in such a way to ensure perpetual resiliency.

Architecting a network as reliable and flexible as ours, and on a global scale no less, is a major multi-year undertaking.

The fact that we built it and continue expanding it into new markets is one of the clearest proof points of the way we go the extra mile to deploy the best possible solutions in each country where we operate. Not to mention ensuring greater control over the entirety of the end-to-end call journey.

It’s really thegeographical spreadof these paired SuperPoPs across North America, Europe and APAC that unlocks reliably low latencies wherever you’re based.

How Have We Architected the Voxbone Network?

Carefully Located SuperPoPs at the Core

At the heart of our MPLS network, 6 core PoPs, or SuperPoPs, paired up in the US (Los Angeles, New York), Europe (Brussels, Frankfurt) and APAC (Hong Kong, Sydney) to ensure our network has the best possible reach across these markets. We call this our “SuperConnectivity capability”.

All our SuperPoPs are built into Tier 4 data centers to ensure complete fault tolerance, redundancy for every component and 99.995% average uptime. All the data centers where our core network infrastructure reside have ISO27001 security accreditation.

We use Cisco ASA/ASR equipment for robustness of access and routing and Dialogic MGW equipment where transition to TDM is still required.

Satellite CollectPoPs to Go Deeper in Key Markets

In addition to our SuperPoPs, we have deployed local equipment in 13 additional countries across Europe and the APAC region to ensure optimal management of local transit in and out of national PSTNs.

These CollectPoPs can be found in Lisbon, Dublin, Madrid, London, Paris, Rotterdam, Amsterdam, Luxembourg, Frankfurt, Milan, Hong Kong Singapore and Tokyo.

The diagram below highlights the dual connectivity that exists between the Voxbone MPLS and each CollectPoP to connect them back to the SuperPoP mesh.

Why Do We Do It Like This?

Ultimately, the network design choices we’ve made since 2005 have been about one thing. Supporting any and all call profiles with a uniformly high level of service, regardless of complexity.

As good as our network is, the magic comes in how we use it to transit call traffic. There are three main technical call flows that Voxbone can deploy in order of preference:

National Operator

national operator

With 28 countries and counting, we are the global leader for National Operator status

 

In these countries, we have national operator status meaning that our network is directly interconnected with the national PSTN. This enables us to transit calls between local calling parties and your own infrastructure in the minimum number of hops. By simplifying the call journey, we can guarantee lower latencies.

Hosted

Hosted

Where we are not a national operator, usually due to regulatory limitations governing providers based outside of the country, our next step is to host with a national operator.

Because calls are routed from the local PSTN to the Tier-1 Operator Network then onto the Voxbone Network, we still have full visibility into the call path.

Partner

tier-1 partner

Sometimes in countries where Voxbone is unable to obtain operator status – due to regulatory requirements or because we have not yet rolled out our full service to this location – we will identify and work exclusively with a pre-existing national operator.

Providing a Uniform Global Experience for Any Call Pattern

All of the above speaks to our mission statement, which is to make business communications strangely simple. Whatever your call pattern or location, our network is built to support it

Some of the usage profiles our network is geared towards include:

 

  • High volumes of inbound calls per second for contact center use cases
  • Long duration calls for conferencing use cases
  • High concurrent inbound and outbound call volumes for global voice providers
  • Audio Pinning within regions in order to optimize voice quality

We offer a different paradigm to the traditional approach of working with dozens of providers and their differing platforms for inconsistent experiences from one country to the next.

Instead, we provide a single interface that hides away the regulatory differences and technical complexities that exist between different national networks for one consistent and uniform experience wherever you want to go.
