Start-up Agito Networks can cut company’s mobile bills with a system that hands voice calls over quickly and accurately between company Wi-Fi and the cellular networks, the company claimed.

Agito’s system uses RF-location to tell when a user is approaching predefined points at the limit of the company’s Wi-Fi coverage. A client on the handset cooperates with the company’s RoamAnywhere router, which integrates with the company’s IP PBXs, so phone calls can be handed over between the Wi-Fi and cellular networks.

The handover takes less than one second, which is much quicker than competitors, according to Pejman Roshan, Agito Networks’ vice president of marketing. “Some solutions centralise call control decisions in the appliance – we take a different approach, distributing processing to the clients.” This is quicker and also more scalable, he explained, since each handset can handle its own calls.
