EVERY call centre in South Africa has been approached by voice over internet protocol (VoIP) or least-cost routing suppliers.

Tim Wyatt-Gunning, joint CEO Storm, says VoIP offers savings across international, national, and cellular calls, whereas least-cost routing only saves money on cellular calls and a small amount on international calls.

Call-centre operators can save about 50% of their costs on international calls, 40% on local calls and 25% on national calls using VoIP through a service provider.

Wyatt-Gunning says Storm pays for its call-centre customers’ VoIP infrastructure, equipment and bandwidth, including the leased line and charges them a rate per second for calls.

“This makes a big difference because a lot of calls are less than one minute, and with the public-switched network the minimum charge is for one minute.”

Due to the interactive nature of the business, on average of 40% calls to call centres are international, whereas in a typical company only 5% to 10% of calls are international, says Wyatt-Gunning. “Half of our call-centre customers are purely internationally focused.”

With overseas call centre operations such as Budget, which provides services to its UK customers from Cape Town, almost 100% of the calls were likely to be international, he says.

SA is an attractive destination for offshore call-centre outsourcing for UK companies because of its favourable time zones, English language and relatively low labour costs. However, the cost of telecommunications that can be achieved in a call centre is not yet quite as low as in competing countries.

However, bandwidth costs are expected to drop by 30% by the end of this year, and then SA will be almost on a par. Once bandwidth costs come down, IP-based solutions will emerge whereby call centres can be set up in major centres and calls can be routed automatically to agents at any location, even to a home office, according to call load.
