Specifically, you can provide a maximum jitter buffer, ; you can turn it off entirely, and you can specify an acceptable ; drop rate (per MEMORY_SIZE, by default 3 of 100). Disabling the ; jitter buffer is generally recommended unless you are on a highly ; jittery network, since usually jitter buffering will cause you additional ; latency. Finally, you can specify the maximum ; excess jitter buffer, which if exceeded, causes the jitter buffer to ; slowly shrink in order to improve latency. ; jitterbuffer=no ; FYI, choppiness is usually NOT jitter ;dropcount=3 ;maxjitterbuffer=500 ;maxexcessbuffer=100 ; ;trunkfreq=20 ; How frequently to send trunk msgs (in ms) ; ; ; Finally, you can set values for your TOS bits to help improve ; performance.
