[Asterisk-Users] Quad T1 Card

the

Also, don't forget that the high-end A104d has more than on-board EC.
It has on-board DSP handling and a 5 year warranty.  Check it out:

Having your T1 card use its muscle to process digital signals can be a
luxury or it can be a necessity.  I say luxury because most T1 cards
that work with * simply let the server's CPU do all of the DSP work.
However, in a demanding environment it might better to let the T1 card
share some of the workload, allowing your CPU to handle all of the other
things that CPU's are supposed to be doing.

Still your call, but if this is a professional install in a
mission-critical environment with significant traffic then the choice
probably has been made for you already...
