Abstract
In accordance with one aspect of the present invention, the detection of voice signals versus modem signals in a data communication system may be conducted, a determination can be made whether existing VoIP algorithm functions or characteristics may be appropriate for modem communications, and then the VoIP algorithms may be modified to improve operating conditions for a modem connection. Additionally, the existing VoIP algorithm functions and network characteristics within the data communication system that may degrade modem performance can be identified prior to the determination of whether the VoIP algorithm functions are appropriate for modem communications. In accordance with another aspect, the detection between voice signals and modem signals can also comprise the determination as to a particular type of modems signal. Further, control of the adaptive jitter buffer to remove or reduce adaptation during detection of modem signals can be provided.
