I think I saw earlier in this thread people arguing the virtues of g729 over g711.
We ONLY do g711 unless otherwise needed.
Why?
In either case, the size of the packet is the same. But, in the case of g729 there is MUCH more info crammed into each packet. Therefore, if you are experiencing packet loss (anything over 3-5% is deadly), you will experience WORSE call quality and/or more frequent disconnects.
Whomever it was that suggested getting rid of diffserve was probably the saviour as that is a waste of time and packets on the internet.

I have seen some modems having a problem and rebooting the modem (at the enterprise end) can fix it temporarily.
If you continue to have packet loss problems get on your ISP's case and don't take no for an answer!
Again, if your packet loss is over 3-5% you will have problems but will have fewer of them on g711.
