VoIP software developed for iPhone

New software for the iPhone means that users of the Apple handset will be able to make calls using voice over internet protocol (VoIP).

Belgium-based Namando Telecom, who designed the software, say the VoIP application could save iPhone users up to 80% on call costs.

Calls to other mobiles on the VoIP service cost from just €0.025 per minute, whilst calls to other Namando users are free.

Mobile operators concerned that VoIP could put them out of business need not worry too much – calls made using VoIP will still incur data usage charges, and Namando is not yet able to provide users with a static telephone number, so money can still be made from calls into the phone.

However, analysts believe that it is only a matter of time before mobile operators are forced to embrace VoIP for themselves rather than seeing it as a competitive threat.

Mobile network 3 already offers VoIP service Skype on some of its phones, allowing customers to make free VoIP calls for a monthly fee.
