Congestion down as VoIP networks take 10 billion minutes off telcos in Nigeria

Share this story

World Telecom Labs (WTL) has announced that more than six billion calls lasting around ten billion (ten thousand million) minutes have now passed through its specialist VoIP switches deployed by five of Nigeria’s interconnect exchange carriers.  This has significantly meant an increase in capacity and a decrease in congestion down as the VoIP networks take achieve this milestone on cellular networks.

WTL has helped the five carriers – Breeze Micro, Exchange, ICN, Niconnx and Solid – to build new VoIP networks across Nigeria with local switching enabled at new POPs in Abuja, Lagos, Port Harcourt, Ibadan and Kano.

The carriers chose to build VoIP networks rather than legacy TDM as it was both quicker and cheaper – and, with the use of WTL’s advanced compression techniques, more calls can be transmitted down the links.

The VoIP networks have significantly improved the quality of voice calls in Nigeria by increasing capacity and taking traffic of congested long-distance inter-city links.

As a result, the latest figures from the Nigerian Communications Commission (NCC) show that since the end of 2013, when the new carriers went live, there has been

  • a 70% reduction in call failure
  • a 50% decrease in dropped calls
  • traffic congestion down by 30%
  • signalling congestion down by 60%

Breeze Micro is headquartered in Kano and works with Nigeria’s operators to transport voice traffic across Northern Nigeria.

“The interconnect exchange carriers were wise to choose VoIP and even wiser to choose WTL whose continued support has been instrumental in improving voice calls in Nigeria,” said CTO of Breeze Micro, Jihad Jaafar.

WTL has been working with operators in Nigeria since 2010 helping them to maximize TDM voice capacity and then migrate to VoIP.

WTL’s range of multi-award-winning VoIP and hybrid VoIP/TDM equipment and services 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 are capable of handling 1000s of simultaneous calls and being used by operators throughout Africa and the Middle East.

“Many people have said that we accelerated the update of VoIP in Nigeria as we made it very easy for the new carriers to build, manage and expand their VoIP networks.  Nigeria has provided the rest of Africa with a blueprint for how they can decrease congestion on traditional voice networks,” said MD of WTL, Leigh Smith.
