Abstract
Methods and systems for preventing information leaks in telephony communications involving any number of parties for use in an IP telephony network having core components. A method according to one aspect of the disclosure comprises receiving an outbound audio and signaling stream from a first terminal device within the IP telephony network, determining call parameters of the outbound audio stream, storing the call parameters within the IP telephony network, and inserting a watermark into the outbound audio stream routed from the IP telephony core components to the second terminal device with an audio watermark using the determined call parameters within the IP telephony network, wherein the watermarked outbound audio stream can be used to identify unauthorized recordings of the outbound audio stream recorded at a second terminal device at which the watermarked outbound stream is received.
