US telecoms company Sprint is to begin trials this week of a service which allows customers to place cheaper international phone calls over its IP-based network.
It is cheaper for carriers to provide calls placed over an IP network than calls placed over regular phone networks, Sprint said, especially for international phone calls, where the differential is greater.
The service, called Sprint Callternatives, will be offered to customers in Atlanta, Dallas, Los Angeles, San Francisco, and Seattle for a limited time. Customers will be able to place calls throughout the United States, including Puerto Rico, as well as India, Japan, South Korea, Taiwan, and Mexico City.
The aim of the trial is to test both the technology and the demand for an IP-based telephony service.
While the voice quality over IP has improved to the extent where Sprint said it felt comfortable offering it to customers, it is anxious to test both the reliability of such a system, as well as gauge customers' demand.
