It would be wiser to know that it has a good chance of working rather 
than "let's do it anyway" :-) I was wondering if anybody on the list has 
similar experience with lots of channels / little bandwith / IAX trunking.

Of course if somebody starts to flood the pipe with bogus traffic, sound 
will be garbage... but then again it could be true with any kind of 
public internet connection. It's just that bigger pipes are harder to 
flood :-/

For the IP/UDP overhead, isn't it something IAX2 trunking is supposed to 
be good for?
