[Asterisk-Users] USB handset wanted

[Bates, Curtis]

I have been playing with an MV100 from mvox (www.mvox.com) and a Phoenix Audio Duet (www.phnxaudio.com).  Both are USB Audio Devices.  With X-Lite, I use them like a speakerphone.  I had X-Lite play the ring to the audio device.  I also used X-Lite's interface for all interaction with it.  

I like the MV100 for my personal use best.  It is small and cheap ($40 at Radio Shack), it also had better echo cancellation.

Matt,

You have forgotten the ringer.
In fact, I don't care that much about LCD & buttons. I want to use it 
with something like X-lite.
Initially, I used machine builtin soundcard with X-Lite (worked well) 
but then I realized that if the phone is supposed to compete with the 
standard analog phone, it must have a working ringer.

 From what I see I suppose that every handset with builtin ringer must 
be recongized to the OS as 2 USB soundcards - one for speaker/mike, the 
second as a ringer.
But I could be wrong.

Our company is completely linux based and If I manage, it will have a 
linux based PBX as well (nothing against Windows, though).
Thanks,

Ondrej
