There was talk of this a week or 2 ago on the list - look into the 
archives. I don't think there was anything that successfull though...

I have to say though - if you have such an integrated unit that needs 
nothing more than an analogue connection (and power, presumably), I'd love 
to know the make - for me, (or rather one of my clients) it would be 
worthwhile trying to find an ATA that would work with it..

Got a name/website for the opener device?
