Voxbone announces that Rebtel's new iPhone application brings one-click dialing to its iNum numbers by allowing users to generate a local phone number that will map to an iNum for any contact in their address book directly from their handset. As a result, people will be able to call iNums – with no access number or PIN to remember – by clicking on a contact icon from over 50 countries for the cost of a local call.

Through its partnership with Voxbone, Rebtel facilitates low-cost international calling by providing users with a local phone number in the country where they live which they can use to connect them with friends, family or work colleagues who live abroad. Rebtel delivers the more expensive international leg of the call over the internet using VoIP, at significantly lower rates than those typically charged by operators. Rebtel's newly launched iPhone application offers a simpler alternative to Rebtel's traditional setup mechanism, in which customers generate local number for their contacts via the Web and manually load them into their phones.

iNum is a different type of global phone number that is not tied to a particular location. Taking advantage of the +883 country code allocated by the ITU, iNums are allocated for free to Internet telephony providers that enable IP communications services to be accessed via traditional fixed or mobile networks. Many VoIP services still use private alphanumeric identities like those for IM or e-mail. iNum provides an ITU-approved e.164 number that is expressly intended for global use with VoIP applications, and enables users to make and receive free or low-cost mobile VoIP calls within participating networks, such as those of Rebtel, Truphone and Gizmo5.
