ABSTRACT:
Method and apparatus for controlling call volume in a packet-switched network is described. In one example, a number of concurrent calls per codec of a plurality of codecs is monitored. A concurrent call limit for each of the plurality of codecs is obtained. For each codec of the plurality of codecs, an indication is generated for each call causing the number of concurrent calls for the codec to exceed the concurrent call limit for the codec. In response to the indication, the call may be blocked or an alternative codec may be selected for the call.
