Speex dev - Dec 2007 - Nominal Jitter buffer Configuration.

Hi All,

 

I have a question regarding the nominal jitter buffer configuration:

 

The call was setup as G.729A (annexb=no), ptime=20ms and nominal jitter
buffer size = 50ms, and round trip delay is 200ms, the TDM side will
experience intermittent one way voice during the call, but IP side can
always heard the voice from TDM side. My question is, should this
possible caused by the nominal jitter buffer? If there didn't have large
network jitter, should the nominal jitter buffer set to 10 or larger and
what's the impact?

 

 

Thanks,
Eric

What do you mean by "nominal jitter buffer"? Also, what version are
you
using?
