Debian + PC to Phone applications

[Neilen <brick@adept.co.za>]

Hi.

I'm currently working abroad of my home county, and calling home over
POTS is very expensive. Great (factor 10-20) discounts can be achieved
if I use a PC to phone provider, such as pccall.com or go2call.com.
However they all seem to require the use of windows software. I suspect
they might work with WINE, but I'm a little afraid of paying to open an
account, and then being left in the cold.

Has anyone had any success using a PC to phone app on Debian/other
Linuxen? And, somewhat importantly, did bidirectional sound support
work?

Thanks
Neilen
