Abstract

A method and system of managing calls over a data network includes determining an available bandwidth of the data network. After a call request is received for establishing a call between at least two network terminals, one or more of a plurality of resource elements are selected in response to the call request based on the bandwidth of the data network. The resource elements, which can include codecs (coders/decoders), packet sizes (for carrying audio data), and others, are used in the requested call between the at least two network terminals. Further, a plurality of communities may be defined each including one or more terminals. One or more usage threshold values may be assigned to a link or links between communities, and a call request is processed based on the one or more usage threshold values. The processing includes at least one of determining whether to admit the call request and selecting resource elements to be used during a call between terminals over the link.
