It all depends on the tarif of your provider - in my case, using VoIPoGRPS is much more expensive than the GSM tarifs (if I call somebody in Austria).

Hello Klaus,

thanks for sharing your experiences. I somehow expected to get miserable voice quality with GPRS and i know about the high latencies.

But beeing able to use a GPRS IP Volume Tarif and using something like this http://www.linuxdevices.com/news/NS5033717348.html with a ported sip soft client is too tempting :)

best regards,
