Echo has nothing to do with TCP vs. UDP. It's an analog phenomenon that
occurs where the hybrid is, where the four-wire circuit changes to a
two-wire circuit.
Anyway I have developed a way to accellerate the adaption

I have been around voice over data packets for quite a few years and I
am still to see the perfect system that works identical to circuit
switching 100% of the time. My opinion is that there is a lot more to
the story than just parameters
Where does the 4 wire change to a 2 wire?

4 to 2 wires happen anywhere the signal goes from digital to a cable
pair. First the digital signal is converted to an analog 2 wire for
transmit and from 2 wire analog
Where does the 4 wire change to a 2 wire?
with just a x100p that would be at the telco in their switching gear
where they do the a/d to route the call
but if you have a channel bank withn T1 to * then you have the a/d at the
telco switch
and then again more a/d when coming off channel banks fxo

What I dont
understand is why MSN messenger is perfect with no echo? I switch back and forth and still hear
a big difference. I believe MSN
is using TCP rather than UDP
I've read and experienced the echo problems with the X100P. Is Digium
going to fix the problem or refund our money? I want to see this work
because myself and other small companies out there use analog lines. I
would trade up to T1 but that requires me to have at least 9 lines. If
I did
