Yep. I was puzzles when rglassband said his Toshiba dealer wanted to keep Difserv on. Useless,a nd even a problamatic when going over the Internet.
A lot of people recommended changing to G729. I have tried to do a lot of things as a test, such as make extreme changes to jitter buffer, ect, and even change to g729. But that will only help if the issue is bandwith related. Both you and I have mentioned delay and jitter a couple times.
Other techs have said that they have had more trouble with VoIP over cable modem then DSL, yet cable always seems to provide much more bandwith to the customers then DSL.
