in case you want to know the other big annoying one:
If you suddenly change timestamp base mid call, sonus will lose 2 sec of audio trying to adjust.
Say you have an ivr that asks you to dial an ext then places the call. While the ivr is the far end and interacting with the sonus there is a series of timestamps generated by FS. Then when the call is placed we start passing through the timestamps from the new farther far end so the jitter can be preserved. (if we rewrite the timestamps to our original ones, any jitter would be locked in place).
With sonus, you pretty much have to set FS to rewrite the timestamps or live with the audio drop =(
Anthony, Thanks for the pointer. It's nice to also know that I won't be able to implement *proper* jitter buffering in my network as long as Sonus is involved somewhere in the call path.
