I've looked at the OpenVox cards and will probably buy one of them next 
time I need an analogue card - eg.

And I've stuck with 1.2 for the time being... There is a patch mentioned 
here recently to make UK callerId work, and also OSLEC is essential (and 
bloody good!)

No experience of this though..

Go back to 1.2. Right now my own feeling is that 1.4 creates more problems 
than it solves - certinly for my application of asterisk (which is mostly 
the SME PBX market and a couple of virtual PBX boxes with SIP and IAX 
trunks).
