SYMPTOMS

Currently, on a computer that is running Microsoft Office Communications Server 2007 and that has the Audio Video Conferencing Server role installed, the Audio Video Conferencing Server negotiates with client computers to use a packet interval of 60ms to send their audio Realtime Transport Protocol (RTP) packets. This may result in some latency and performance issues over low bandwidth connections.

This hotfix changes this interval to 20ms. This shorter interval may result in improved latency and better performance in calls over low bandwidth connections.
