asterisk users - Apr 2008 - OT Good Price $.099 - Voip/ Skype PC Handset UP609 "Regular $29.99"

http://www.surpluscomputers.com/store/main.aspx?p=ItemDetail&item=CES11532

Ground shipping $9 to MD.  Never used so I cannot comment on quality
and Linux is not listed as compatible but I suppose as long as your
audio jacks work, then the handset will too.

Unfortunately, shipping goes up linearly with units ordered.

Thanks,
Steve Totaro
