OK, so, if you turn off EC, everything works right?

EC was actually _really_ broken recently, as the libspeex API to it 
changed, and our code didn't. So we were passing in arrays of float, but 
it now expects arrays of short.

I actually just changed this about 10 minutes before I read this mail; I 
was going through things to eliminate the warnings in the original 
iaxclient code (as opposed to the tons of warnings thrown by GSM and 
libiax2).

However, the EC is still experimental at best.  It probably won't help 
you to use it, and it will often make things worse.   It's a great area 
for someone with some audio processing experience to contribute (by 
working with the speex project primarily).
