linphone has a simpler echo limiter that can be used if there isn't enough cpu 
for the proper echo canceller, or if the level of distortion is too high for 
it to work properly. It lowers or mutes the mic when the speaker level is high 
so you effectively get half-duplex calls. It's not ideal, but probably better 
than echo!
