Currently MG2, but I prefer OSLEC.  MG2 works better, not better
than OSLEC, if you can use fxotune to set the echocan coefficients,
which is why it's better now compared to old zaptel.  I'm not even
sure if while it was reporting MG2 on zaptel (1.4.7 an that time)
it was actually using it.

You've done a great job porting this to FreeBSD.

Thanks
