World Telecom Labs (WTL) has announced that Zamir Telecom is using its specialist VoIP optimisation equipment to improve the managed VoIP service on its London to Dhaka route. Zamir has deployed WTL's specialist VoIP switches at either end of the dedicated IP fibre link – on which traffic peaks at around 20 million minutes a day – to improve the quality of calls, ensure that the network is always available and to optimise bandwidth capacity without compromising voice quality. According to the press release, the superior call quality now enables both Zamir's retail business and its wholesale customers to market their London to Dhaka route as a 'premium route'. One major Zamir wholesale customer is Bangladeshi incumbent fixed line operator BTCL, for which Zamir's wholesale business acts as a Point of Presence for BTCL to convert high volume IP traffic from London to TDM for onward transmission.
WTL's switches are designed to replace the expensive, maintenance-heavy switches that have traditionally been used to transfer VoIP traffic onto other networks, and its press release claims that the optimisation will cut Zamir's costs by a significant amount while improving the quality and reliability of the calls on the London to Bangladesh route. WTL has also provided Zamir with a SS7 Signalling controller to manage its fibre interconnections in Bangladesh. WTL's VoIP optimisation services and equipment are also being used by a number of operators throughout Africa and the Middle East, according to the release.
Zamir offers wholesale international termination and managed voice, data and IPLC services for other service providers, as well as a retail arm – SimpleCall – which is a global B2C service provider for international calling services and also a mobile virtual network operator (MVNO) in the UK.
