VOIP providers in the U.K. will have to provide clearer information about the services they offer under new rules announced Thursday by the U.K. telecommunications regulator.
The service providers will have to be clear about whether or not they allow customers to make calls to emergency services, the U.K.'s Office of Communications (Ofcom) said. They must also disclose whether they provide directory assistance and access to an operator, and whether customers can ask for an itemized list of calls.
The regulations -- the first for the VOIP industry in the U.K. -- take effect from June.
Up to 3 million U.K. consumers expect to be using VOIP services by the end of the year, Ofcom said. The new rules follow a public consultation last year that was intended to help consumers make more informed decisions about VOIP services.
Ofcom will hold a further consultation this year to determine whether VOIP providers will be required to provide access to emergency services, since being unable to could be detrimental to consumers, it said.
In the U.S., the Federal Communications Commission has banned companies from advertising VOIP services if they do not allow people to call emergency services.
"In assessing the need for any new requirement, we will continue to carefully consider the impact of such regulation on market entry, innovation and competition," Ofcom said on its Web site.
Operators must also be clear about whether their service will work in the event of a power failure, Ofcom said. Many VOIP services depend on a powered router for Internet access, so if the home power supply were cut off, the VOIP service also would not work.
Operators such as BT Group PLC offer services where both VOIP and regular landline calls can be made from the same phone, which avoids difficulties in making calls during a power outage.
Providers that don't offer emergency service calls and don't work without a power supply must display warnings on their products, Ofcom said.
VOIP providers will also have to disclose whether customers can keep their same phone number if they switch providers, Ofcom said.
