While not over gsm/umts, I do use VoiP over WiFi from my mobile phone. 
Since I have Wifi at home, work and pretty much every friends place - my 
gsm usage has become quite low. Only time you really need it is when you 
are out and about.

I've tried using it on Vodafone/3g, but latency seems quite high. I can 
register with the provider and login, but most calls dont get placed. 
The ones that do, keep dropping packets. Plus, with data charges being 
what they are - the economics might not work out.
