Crazytel Global Infrastructure
One of the world's most resilient multi-redundancy, geo-distributed voice networks. Built for maximum speed, security, and uptime, and expanding globally every single day.
Our global switching cores and gateways
Engineered Differently
Most providers use off-the-shelf equipment and sugar-coat their claims with buzzwords. We think outside the box, design our own specialised software, and run our own multi-redundant physical voice infrastructure.
We are incredibly proud of our network's dual-redundancy. When we say redundancy, we don't just mean generator back-up in our datacentres. If one of our physical locations experiences a catastrophic connection or hardware issue, our system is programmed to automatically disconnect and safely reconnect your device or VPN tunnel to an alternative active location in under 60 seconds.
If a datacentre fibre break or power failure occurs, our Operations Team can trigger a custom-engineered, physical site-wide “Kill Switch” that instantly isolates the affected node and routes all ATA, IP phone, and SIP traffic to our alternative cores. Everything is back to normal in less than 60 seconds, completely avoiding the headaches of standard carrier downtime.
We own and build our software stack. Major telcos rely on bloated, incredibly expensive third-party systems like Broadsoft. We prefer to invest our capital directly back into our in-house systems and expert engineers. Our core voice networks are based on highly customised, hardened open-source solutions including Kamailio, OpenSIPS and FreeSWITCH (we do not use Asterisk), ensuring massive scalability, secure voice pathways, and elite stability.
We believe in high-performance bare-metal speed. DELL supplies all of Crazytel's core bare-metal physical servers, while MikroTik provides the enterprise switches and optical interconnections that link our network core equipment. No shortcuts, no underpowered virtual machines—just pure, enterprise-grade muscle.
Our Network Operations Centre (NOC) is equipped with over ten 32-inch high-definition screen arrays monitoring our global network metrics 24/7. In the rare event of a node anomaly or latency spike, automated alerts notify our team instantly. High-priority alarms guarantee our engineering team is actively investigating within seconds.
Our infrastructure is maintained by a specialised team of network engineers, Linux administrators, and open-source VoIP developers across Australia and the USA. Even our support centre staff possess professional backgrounds in VoIP systems, giving you immediate access to real technical experts when you need them.
Our Carrier Department continually negotiates direct peering and transit with premium Tier 1 telecommunication carriers globally, bypassing cheap public routes to deliver crystal-clear voice clarity.
We are constantly expanding. In addition to our new Asia-Pacific nodes, our engineering team continues to extend and strengthen the network every single day.
We spare no expense when it comes to quality. From high-throughput dark fibre leases to optimised border gateway protocols, we continuously iterate on our network every single day.
