echo cancellation is pretty limited on these cheap devices. the spa3000 
manual for example states the AEC is limited to 8ms. good AECs will handle 
64ms or more. in my experience the spa3000 echo canceller is cranky. it 
works most but not all of the time.

also, the spa3000 is only 10mbit.

if you can, get something with a good hardware echo canceller.

sangoma has a new line of FXO products. they're a bit spendy but look very 
nice.
