Hi Scott,
Intresting to know, cheers :)
Only down side though, is that most people using softphones will be using Windows...
If only ALSA was available for windows ;)

That should be the program alsamixer, not amixer. Make sure to press F5 to get all of the playback/capture devices shown.

Ah, Console sound card echo.
I found that with my cheep YMFPCI sound card that there is a channel called "wave capture" that is enabled for recording by default. And this is only visible when one uses ALSA sound drivers. One needs to use an ALSA mixer control program (I use amixer, the text mode one) to disable, or reduce the volume on these sound cards. Once this is done there is no more echo at all!
Why this channel does not appear under OSS, and why it appears to be enabled by default in the hardware is beyond me. The GUI mixers all list this channel simply as WAVE, and I have two WAVE channels. So remember amixer.
The card is called ICEnsemble ICE1230 by OSS, and Yamaha DS-XG (YMF734) by ALSA

We just tried to go entirely with softphones in our office gave up after a month or so of trying. I tried probably 10 different softphones running on 3.0Ghz WinXP machines and none of them were workable. I tried both SIP and IAX2 softphones using headsets plugged into the audio ports, USB headsets, and USB phone interface boxes (www.phoneconnector.com).
While it wasn't hard to get them to work and the concept would have been perfect in our environment, the quality was _terrible_! We had many issues

I found that for the most part, crappy sounds cards caused the bulk of problems with soft phones.
I noticed that on, for example, intel D865PERLL motherboards with an onboard realtek AC97 sound
device, There was heaps of echo for the remote end (using a softphone or a hardphone).
I also found that a stock standard Creative PCI 128 sound card gave great results.
Given PCI128s arn't available anymore, I'm sure you could find an alternative, like perhaps
even going as far as a SB Live Value.. if you buy these in bulk, im sure you can get em cheap
as chips.
I've only ever used X-lite as a soft phone and found it to be really very good.

A: No, sir. I was shot midway between the fracas and the naval. _______________________________________________
