Telecoms regulator Ofcom has announced a new regulatory code for VoIP providers to ensure that consumers understand the capabilities of their service. 

Companies offering a VoIP service in the UK from June 2006 must inform customers whether they have access to emergency services, and make it clear whether the connection will be cut off in the event of a power outage.

Providers must also make it clear whether services such as directory assistance and listings are available, and tell customers whether they can keep their telephone number if they decide to switch providers at a later date.

"Ofcom has decided to put in place measures to ensure that consumers have access to information which helps them make informed purchasing decisions," said an official Ofcom statement.

"As VoIP usage in the UK continues to grow, and the market develops further, Ofcom will continue to review and develop its approach to regulation to ensure that consumers gain the full benefits of VoIP services."
