Abstract:
An Internet protocol (IP) telephony system provides telephony services to a mobile telephony device via data packet communications that traverse a data network. If the IP telephony system has received calls that were missed by the user of the mobile telephony device, or if the IP telephony system has received communications that have not yet been reviewed by the user of the mobile telephony device, information about those missed calls and unreviewed messages is delivered to the mobile telephony device so that the user can be alerted to their existence. The information may be delivered to the mobile telephony device in a push notification.
Abstract:
Systems and methods for terminating telephony communications to a mobile telephony device that is roaming outside of its native service area make use of a forwarding termination service. The forwarding termination service causes the native mobile telephony service provider that provides service to the mobile telephony device to forward incoming telephony communications directed the native telephone number of the mobile telephony device to a forwarding access number. The forwarding termination service receives telephony communications directed to the forwarding access number, and then terminates the telephony communication to the mobile telephony device via any one of multiple different methods. The mobile telephony service provider can be instructed to implement and cancel call forwarding instructions by dialing a special character string on the mobile telephony device.
