[Coco] Using a coco modem with VOIP

[Dave Philipsen]

I imagine the thing about Magic Jack might be that since it is free (so I have heard) then they probably force one of the lower quality codecs with more compression.  Maybe that’s why it doesn’t want to work with the analog modem. 

I was doing a bit of research on this and found that there is apparently some method designated as T38 for fax transmissions over VoIP. This apparently allows old analog fax machines to continue working on VoIP systems as long as you’re using VoIP equipment that supports T38. My guess is that something similar (if not the same) could work for connecting the old analog POTS modems to a VoIP system. It’s just that there probably isn’t much of a demand for that sort of thing since most people have abandoned the old analog modems.
