These are two parameters that influence the total number of supported conference participants on a Cisco IOS XE router that has DSP modules2. A voice codec is a software algorithm that compresses and decompresses voice signals for transmission over a network3. Different voice codecs have different bandwidth requirements and quality levels3. A PVDM module is a hardware component that provides digital signal processing (DSP) resources for voice applications such as conferencing and transcoding1. A PVDM module has a fixed session capacity, which is the maximum number of voice channels that it can support simultaneously1.
