Abstract
A system, method, and apparatus are directed towards a system, method, and apparatus for managing a communication session by dynamically selecting a CODEC. A client device requests a communication session with a receiver device. If available, historical information may be used to establish an initial CODEC and its associated sampling frequency for the communication session. Signals, such as a white noise signal, and/or a ring tone may be sent between the client device and the receiver to determine a metric for the communication session. The metric may be used to adjust the CODEC and/or its sampling frequency for the communication session. In one embodiment, if it is determined that the sampling frequency is less than a minimum determined value, a message may be sent to the client device advising that the current communication session be terminated.
