Voice-Over-IP Call Recording in Call Centers

摘要

An apparatus and methods are disclosed for recording calls in a Voice over Internet Protocol (VoIP)-based call center. In accordance with the illustrative embodiment, one of a plurality of data-processing systems in the call center is selected for each call to decompress and decrypt the call's media stream(s). The selection criteria include the type of compression algorithm, the type of encryption scheme, the processing capabilities of the data-processing systems, the current processing load of the data-processing systems, and the available communication bandwidth into and out of the data-processing systems. The selected data-processing system is subsequently incorporated into the call path between the calling SIP endpoint and the call center SIP endpoint, if necessary, and for the duration of the call decompresses/decrypts the media stream(s), generates a copy of the decompressed/decrypted stream(s), and transmits the copied stream(s) to a recording device in the call center.
