[Asterisk-Users] usb phones in linux, any??

[Paco Perez]

Hello:
I would like to know if anybody has test various usb phones with an usb hub 
conected to an asterisk server.

The idea is to build a public telephony site with one or 2 analog cards 4 or 8 
FXO, least cost routing and billing and usb handsets with dialpad for users, 
so I really don't need a graphical interface for the soft phone ( the users 
just dial from dialpad).

Any has done this before...

thanks
