Roaming VoIP/Mobile VoIP

Convergence is a major trend that is dramatically changing the telecom environment. New players, technologies, devices and business models are beginning to flood the market. Internet and roaming VoIP providers are moving into the mobile arena with services that promise complete mobility and appealing price models.
Mobile VoIP providers can offer users international calls via IP/Wi-Fi access that is available in most locations. Mobile operators are seeking to avoid churn to alternative technologies and service providers, and the subsequent loss of revenue, by offering their own attractive convergent mobile-to-IP roaming service.
The Starhome® Mobile2IP™ offers subscribers the ability to simply connect their laptop to any IP network. This connectivity allows them to make and receive mobile calls with Voice over IP (VoIP), using their own MSISDN.
Mobile2IP provides GSM to IP and IP to GSM mobile services. The solution allows users of different devices to route incoming calls to their IP Soft Phone, GSM phone or both, according to the zone they are in (IP/GSM) and their preferences. For example, a user can be in a hotspot and choose to receive a call on either their laptop or through their mobile device via their Mobile number.
Mobile2IP allows mobile operators to prevent the leakage of subscribers who are looking for roaming VoIP alternatives to national and international phone costs. Mobile operators provide subscribers with the ability to simply connect their laptop to any IP network and make and receive mobile calls over VoIP using one number - their own MSISDN (Mobile Station Integrated Services Digital Network).
Moreover, Starhome's Mobile2IP solution provides the mobile operator with the ability to offer roaming VoIP services to its end users while they are connecting the service from their home country, and/or while connecting from abroad. Mobile2IP resolves the origin IP address (of the end user's soft phone) and its associated country location provides the mobile operator with the flexibility to activate/deactivate the service (black/white list) per desired location (country level).
