Call Centers, Leaky PBX, Grey Markets

There are lots of reasons entities set up call centers: sell products; answer questions; technical support; fund raising; set up appointments.

Or, in some cases, to create not-quite-legal terminations for international long distance. Sometimes known as "leaky PBX" operations, the motivation for doing so is money. Significant amounts of money.

By some estimates, 30 percent or more of inbound global calls to Indian numbers are terminated outside the carrier-to-carrier settlements regime.

Estimates of traffic that skirts the settlements regime range upwards of 3.5 billion minutes a year or $150 million to $300 milliion a month that otherwise would have been earned by a licensed carrier.

In recent years, global carriers have paid Rs 5.50 in termination charges to an Indian domestic telephone company. In a leaky PBX or "grey market" operation, a service provider launders the traffic, making it look like a local call, avoiding the termination charges. This saves the global carrier about half what it otherwise would have paid. And the local termination network gains revenue because it makes money from the higher volume of traffic it gains.

The most popular grey market routes serve mobile phone traffic in high-cost termination markets. And that's where the call centers come in.

Grey routes often are created by call centers, as VoIP in some markets is legal when it is IP-based endpoint to endpoint. Until the laws change, and as India market mobile penetration climbs, so will the grey market.
