Voxbone has collaborated with JAJAH to develop a value-added telecommunications service that makes international calling simple and affordable. The International Favorites service, which Jajah provides for mobile customers of O2 in the United Kingdom, offers a subscriber a virtual overseas number so friends and family abroad can call at local rates.

As part of the new service, Voxbone supplies an international “Call Me” number that directly reaches a customer’s mobile phone.

The customer adds this second phone number from a country of choice to an existing mobile subscription. Calls to the number are dialed, delivered and billed like local PSTN calls. These calls are transmitted through Voxbone’s IP network to the O2 user’s mobile phone. The subscriber doesn’t need a special phone or application.

The virtual number complements the subscriber’s U.K. mobile number, enabling two phone numbers to be mapped to the same device. The service works with most O2 phones.

In addition, Voxbone is supplying numbers for another feature of International Favorites: provision of three local outbound numbers per subscriber that the customer may use to reach selected international landline and mobile numbers. A flat fee of £10 per month covers 3,000 minutes (50 hours) of calls to these numbers.
