Simwood's focus on VoIP uptime, fraud prevention and real-time APIs helped the wholesale network operator to secure a deal with the London Internet Exchange (LINX) for the provision of reliable voice services.
As one of the world’s largest Internet Exchange Points LINX provides a meeting point for 600-plus ISPs including Simwood. The London network currently handles approximately 5Tbps of peak traffic and is within reach of around 85% of the global Internet.
"Having previously deployed VoIP internally in and between its two offices, LINX wanted to embrace the wider benefits of VoIP while enhancing availability," said Simwood CEO Simon Woodhead.
Simwood operates an IP network spanning Edinburgh, Manchester, Slough and London and is built for high availability.
It also operates its own SS7 interconnects to BT and Virgin, each in multiple sites.
The VoIP stack is distributed throughout the network and at each level is able to fail over between sites. It has no dependence on and competes directly with services from other operators such as BT's IPExchange, noted Woodhead.
"It was a joy to receive an RFQ stipulating requirements that matched our USPs from such a technically competent organisation," added Woodhead.
"The process was exhaustive right down to an examination of fibre maps and failure scenarios, because if LINX sneezes the Internet catches a cold."
LINX CTO Richard Petrie added: "We want the flexibility VoIP offers, but not at the expense of availability. And Simwood's achievements on VoIP fraud mitigation and excellent real-time API were a welcome bonus."
The solution is currently in the deployment phase and will be brought into service over the coming months.
