[Asterisk-Users] jitter buffer recomendations

[1 2]

Hi

I seem to be getting  about 250-500ms drop outs on
receive audio for some calls that are routed over the
internet. Probably no news there.

My end point is a polycom 500 and was wondering if
anyone could recommended jitter buffer settings.

codec is alaw
min buffer is at 40ms
maximum buffer is at 200 ms
shrink rate is at 3000ms

I think i am getting less than 40ms jitter most of the
time - would the approx 250ms audio drop refer to the
amount of time it takes to start buffering? Maybe I
should reduce the minimum buffer so it is always on?

Any tips from the field appreciated.

Thanks

J
