[asterisk-users] Problem with modem data calls and xorcom astribanks

[Greg Woods]

I have been told before on this list that a modem through a zaptel card
will not work. And mine doesn't, at least not for data calls (it works
fine for fax). Apparently the modem requires the full bandwidth of the
POTS line, which you do not get through the zaptel card.

You might at least check to make sure that echo cancellation is turned
off. That can interfere with a data call.
