Latest Patents

One of Keast's latest patents focuses on authenticating voice calls from mobile devices. This invention relates to authorizing mobile devices for PBX-based voice services. In this system, a mobile device calls a PBX over a voice channel, and phone number identifier information is obtained and matched to identifier information for devices that are known and authorized to use the PBX. If there is one incoming call that matches a given device, and an authentication token provided over a data channel matches an authentication token associated with that device, then the device is authorized for voice services. In cases where multiple matching calls occur, those devices are instructed to provide authentication tokens over their voice channels. The devices can detect the absence of a data channel and provide authentication tokens over the voice channels. They can also wait to receive a call connected response and, in the absence of such, provide their authentication tokens over the voice channel. Additionally, tokens can be requested and downloaded for storage at the devices.
