Abstract: A method and system (500) for optimizing transcoder resources in a multimedia session is disclosed. The method includes receiving (202) one or more SDP offers. The method further includes filtering (204) out media types from each of the one or more SDP offers based on a rating range. Further, the method includes selecting (206) one of the media types from each of the one or more SDP offers. The method further includes allocating (208) resources of one or more transcoders for transcoding the one of the media types.

Abstract: A method for load balancing call traffic in a telecommunication gateway is disclosed. The communication gateway comprises a plurality of media gateway controllers and a plurality of media gateways. The media gateway controllers and the media gateways are coupled in a many-to-many relationship. In a first step of the method, a status request for a load level is sent from one of the plurality of media gateway controllers to each of the plurality of media gateways controlled by the one of the plurality of media gateway controllers. Next, a reply containing a load level is received from each of the plurality of media gateways. Then, a proper media gateway from the plurality of media gateways to route a call is determined based on the load level.

Abstract: Various embodiments are described to address the need for a method and apparatus of voice transcoding in a VoIP environment that effectively interconnects multiple voice encoding formats. In general, a packet-based tandem transcoder (201) receives (706) packets that include vocoder data frames in which source voice samples have been encoded according to a first vocoding format. The transcoder then decodes (708) the vocoder data frames to produce a sequence of linear speech samples. Using a non-circuit switched communication path, an encoder obtains (710) linear speech samples from the sequence of linear speech samples and encodes (712) groups of speech samples from the sequence of linear speech samples to produce vocoder data frames according to a second vocoding format.

Abstract: A transcoder (40) includes a method for assigning transcoder channel elements (43, 44). The transcoding assignment method selects a DSP (60-75) selects a DSP (channel element) of the required type which has available channel elements (98). Further, the transcoding assignment method may dynamically reassign (118) DSPs from one channel element type to another.
