Patent ID: 8180331

Claim:
A system for controlling communications between a call control server, a wireless handheld telephony device, and at least one second telephony device, the system comprising: a data processor; a modem configured to modulate signals received from the call control server and to demodulate signals received from the wireless handheld telephony device; a communications system adapted to process signals sent between the wireless handheld telephony device the at least one second telephony device, and the data processor; and media readable by the data processor comprising coded program instructions adapted to cause the processor to: establish a communication session with the modem device; receive modulated control signals from the call control server via the established communication session with the modem device; transmit modulated control signals to the wireless handheld telephony device through the audio channel of a leg of a communication session previously established between the wireless handheld telephony device and at least one second telephony device; upon receipt of modulated response signals from the wireless handheld telephony device, transmit the modulated response signals to the modem in communication with the call control server; and transmit modulated response signals received from the wireless handheld telephony device via the established communication session with the modem device, wherein the media server is configured to establish a communication session with the modem device when one or more signals are to be sent, and to temporarily suspend a communication session with the one or more second telephony devices; and, when the one or more signals have been sent, re-establish the communication session with the one or more second telephony devices.
