Does anyone here have any experience using phone audio as input? I am 

looking for a way to connect multiple phone lines (at least two), or 

multiple VOIP sessions, to a Mac and have each line appear as separate 

audio input channel. Either an analog or a VOIP solution would work, as 

long as I could get a separate audio channel from each voice connection.

I know there are PBX solutions for the Mac like Phlink 

 as well as various VOIP clients, but I'm 

not sure how or if they can be made available to Max as inputs.

hrm yeah I would also like to know how in teh fuk one would record phone conversations, or pipe audio from the phone into a soundcard. Haven't done much, where much = any, research on the subject.

Although it doesn't seem to be quite what everyone has in mind, there is 

a transducer from radio shack made specially for recording phone 

conversations. It has a black suction cup that sticks to the phone 

speaker, and it plugs in with an 1/8" jack into whatever input you have. 

This seems like it would be the simplest way to go IMO. I don't 

think any more fidelity would be lost than was already is over the trip 

through the multiplexing what-have-yous in the phone lines.

Yeah, hah. While I was writing the above, my brain was going "Don't bother writing this, they probably sell something at radio shack" over and over again. =X Damn, need to start listening to myself more.

Try sending them an email. They may send it to you for cheaper.

One of my favorite places to go waste an afternoon in Orlando. Right 

up there with the theme parks, although no coasters. I am sure other 

They also have them here:

I never had any luck worth mentioning with that suction-cup mic. In my 

experience they don't even come close to line quality. You might even 

be better off using a DIY contact mic (about the same price); there are

Look for Wojciech Kosma's skype object here:

I have not used it, but I'd be curious to know how well it works,

Phone audio input?
