Abstract: A method and system for integrating compliance and contact management between an origin and destination. An integrated control system can receive or initiate a request for a first communication contact type (e.g. phone call) between an origin and destination, the request including a first destination identifier (e.g. phone number).

Abstract: One exemplary problem addressed by the techniques disclosed herein is that the A-to-D converter of the broad-band audio codec that is being used more frequently in IP telephony, G.722, samples the analog audio source 16,000 times per second, rather than 8,000. Since all G.722-capable telephones must continue to be G.711-capable, one problem is that a microphone that provides appropriate bandpass filtering for G.722 encoding fails to provide adequate filtering for G.711. One exemplary aspect is therefore directed to telephones that must be able to switch back and forth between narrow-band digital audio encoding in which the A-to-D converter samples the audio stream 8,000 times per second, and a wide-band audio encoding in which the A-to-D converter samples the audio stream 16,000 times per second. This is accomplished using one or more of a plurality of switched microphones, a filter and a modification of the resonant frequencies of a handset.

Abstract: Embodiments relate to a filtering device that filters a telecommunications signal and outputs to a telephone and a data port depending on whether a data plug has been inserted into the data port.
