World Telecom Labs (WTL) today announced that Roshan, Afghanistan’s leading communications provider, has chosen its specialist 2nd generation VoIP switches to help improve the quality of calls and reduce the costs of voice traffic between its international gateway in Kabul and its VoIP point of presence in London.

Roshan’s dedicated international VoIP network allows it to easily collect traffic into and out of Afghanistan whilst keeping full control of the International hub’s inbound and outbound voice quality.

WTL’s award-winning range of 2nd generation VoIP and hybrid VoIP/TDM switches have been specifically designed to replace the huge, expensive, maintenance-heavy switches that have traditionally been used to transfer VoIP traffic onto other networks. They provide operators with a cost-effective and evolutionary path to VoIP and have been deployed by multiple operators throughout Africa, Asia and the Middle East.

Roshan will benefit from the innovative Network Optimisation Protocol (NOP) compression techniques embedded within WTL’s 2nd generation switches. Benefits which include:

· Increased capacity - WTL’s unique compression techniques reduces the amount of data used per call and enables a higher density of calls in the same bandwidth whilst maintaining high QoS.

· Greater flexibility and reliability – WTL makes it easier for Roshan to increase and reduce capacity as demand fluctuates, at the same time maintaining reliability under heavy traffic loads.

· Interoperability – easy to integrate with Roshan’s existing infrastructure

· Fully redundant – WTL has created a self-healing, clustered architecture that gives n+1 redundancy. One of the advantages of this is that in the case of one server failing the extra traffic is distributed across the others.

Leigh Smith, MD of WTL, said “Many operators which use VoIP don’t realise that there are many ways to increase capacity, reduce costs still further and improve voice quality. Our team has extensive experience in compression techniques which continue to impress the operators we work with.”

In September WTL’s 2nd Generation VoIP switches were named as The Best Telecom Innovation at this year’s Nigerian Telecoms awards. They were shortlisted in the Global Capacity awards which recognise expertise in the global wholesale market. They were also shortlisted twice in this year’s AfricaCom awards in the Best Cost Efficiency Solution for Africa and Best Network Improvement categories for deployments with Nigeria’s Interconnect Exchange Carriers which have built new inter-city VoIP Routes using WTL’s 2nd Generation VoIP switches.
