[Asterisk-Users] How to use a data T-1?

[Warren]

Well that is certainly all good news.  The last hardware question I
would then have is: What do you do for Echo Cancellation with this type
of setup?  Everyone keeps saying that the software EC basically sucks to
put it bluntly.  Is there some sort of hardware to do EC that can be
used here?
