I use the Gentner Micro-Tel (similar to the JK "THAT-2") for getting audio in/out of a telephone circuit.

I didn't say I had a goal....just curious.
I don't have a particular need, at this time, but I find the options people are offering are quite interesting.
Mostly, I am able to get a POTS line but sometimes we need to send outbound audio to a conference bridge and only have access to in house "digital" (can't think of the correct word) phone systems.

I go back to my statement, a soft phone on a PC with a quality audio interface could make a call via a VoIP provider with a low loss CODEC and if you Internet connection is good quality will be well above any 2 wire hybrid device connected to a POTS line.

Sorry to revive a somewhat old thread but...
I'm curious about the acoustic echo cancellation issue.  As has been said alreayd, with a VOIP system through computer you have the 4 wire (separate in and out) for free but what about the quality (or perhaps suitability is a better term) of the echo cancellation with various VOIP systems?  I have to assume that echo cancellation for a laptop with built-in speakers and mics is a different animal compared to a panel of lav mics and a full PA system.  In particular, aren't the algorithms tuned somewhat based on latency?

Going back to the basis of this thread, the original idea was how to get telephony sound without using a Gentner or other expensive interface. While the interfaces do the job very well, some are confusing to set up and others simply too wiz bang for what most are trying to do. If your going to send video with audio Citrix, Skype and a few others are the best way to go. Shoot, if your going to go that route you could even simply run multiple live instances of Ustream.

A way of doing audio only, would be a VoIP converter as I mentioned earlier. For cancellations I think it depends on user setup. You could invert the polarity of one side of the audio conversation and that might do most of the work for you. I think that most converters are going to work the cancellations out for you already though. Not to mention that if you designed and deployed the PA well, there will be minimal issues from loop back anyway.
