Overview Network wide choppy video, music on hold streams or loud speaker issues are commonly caused by multicast problems in the network.  Should the issue be network wide and not isolated to one area of the network, the next place to start looking is high CPU on the First Hop Routers (FHR) and/or the Rendezvous Point (RP).  When the CPU process is high...
