How about echo in the channels ? This is a big usability issue for me :-(

Ok, the pricing range is pretty high and it doesn't seem to be active in 
any big way.. Would an Eicon Diva Server BRI be more usefull ?

I have tried a variety of ISDN cards with I4L and a Fritz!PCI with CAPI and 
on my 1.8Ghz machine I am still not entirely impressed. My users complain 
(seems to be related to when the remote is an analogue line) about echo. 
The SIP endpoint has an echo-canceller. Doing calls over an X100P and my 
old DAC might work better, but loses a lot of functionality (CallerID, 
incoming MSN) :-((
