[Off topic] Best PCtoPC internet phone?

[Simon Campbell <simtrader@xxxxxxxxxx>]

I want to talk (over an internet connection) to one other trader in another 
country during market hours.  Can anyone recommend a PC to PC telephone 
program that:

- Avoids using ICQ (potential delays/congestion?)
- Direct IP to IP address contact
- No banners/advertising
- Good audio quality

Thanks in advance
Simon.
