I've been using the Digium TE110P for more than a year now without any
hitches in a mission critical environment.  It's in a Dell Poweredge
750.

I had a problem compiling libpri at first and the digium help desk was
more than helpful.  I also had some echo issues, but those have mostly
been resolved using the built in cancellation routines.
