Abstract:
1. A method for controlling a telephone network for telephony based remote location monitoring, comprising: responsive to receiving a caller request to listen only to a remote location telephony device by a channel allocation controller of a telephone network, allocating, by said channel allocation controller, a half duplex listen only channel between a caller telephony device and said remote location telephony device via said telephone network; activating, by said channel allocation controller, a microphone at said remote location telephony device via said listen only channel by a signal transmitted from said channel allocation controller to said remote location telephony device; streaming audio detected at said microphone via said listen only channel to said caller telephony device, such that said channel allocation controller of said telephone network enables a caller to monitor a remote location through said remote location telephony device with minimized allocation of telephone network resources.
