[Asterisk-Users] USB handset wanted

[Bates, Curtis]

I was using in on Windows XP, so it was a single device for both microphone and speaker.  Have not tried it on Linux.

Question:
Did they behave like 1 audio device (for the speaker and mike) or 2 
audiodevices (creating /dev/dsp1, /dev/dsp2) with the second one for the 
ringer?
That's what I am unable to find out...
Thanks a lot for the tips....
