20110044317 | REAL-TIME VOICE LOGGING OF TELEPHONE CALLS - An office telephone system contains packet switched network and network telephone sets coupled to said packet switched network for transmitting and receiving speech data in addressed packets. A packet switched network interface taps the packet switched network and processes packets received from the packet switched network by identifying first and second packets that contain network voice call data for respective sides of a network telephone calls. The packet switched network interface mixing speech data from the first and second packets into streams while the call proceeds. Each stream comprising a mix of speech data from both sides of a respective one of the network telephone calls. An application program interface defines provides access to the streams to a programmable set of applications. In addition a line interface circuit taps call dedicate telephone lines outside the network and generates further speech data streams from signals from the call dedicated telephone lines. The application program interface defines provides interchangeable types of calls to access streams generated from both sources. | 02-24-2011 |
