asterisk users - Jan 2004 - Credit Card Terminal

Hello,

I have a Hypercom T7P swipe card terminal sitting on a dedicated G711ulaw
port.  The Hypercom operates at either 1200 or 2400bps.  I get about a 50%
success rate when I try to authorize cards.  On this same G711ulaw port, I
have a fax machine with a 100% success rate operating at 9600bps.  Any
suggestions on how to change *, ATA186, or SIPURA SPA-2000 to enhance the
card terminals ability to process would be appreciated.

Regards,
Christopher J. Wolff, VP CIO

Sipura recommended disabling the echo cancellation on the SPA-2000 for
modem pass-through.  It does help although still not 100% success rate.
