Bandwidth Requirements for VoIP Monitor Service
Although the bandwidth requirements are the same between the VoIP Monitor service and the Desktop 
Monitor service, the VoIP Monitor service can handle more simultaneous sessions (since it runs on the 
server). 
 expand upon the 
 by increasing the number of
