IP Telephony again

Since the last time I posted about IP telephony, I've discovered that it's possible to use the Tesco USB telephone handset (including the dial buttons) with a number of popular softphones (ie. those that run as a program on your PC). Why does that matter at all ? Well they're currently on offer at Tesco's for a midge's whizzer under £15 and the sound quality on a call isn't bad at all.

A trip to here or here is all that's required to download the appropriate helper application.
