Yes, it is because of the delay. GPRS is just too slow for voice
communication.
I meant to write "CSD or HSCSD" there, sorry for the
confusion ;-)
As far as I know, CSD data connections are not included in the
data-flatrate E-Plus provides. I've asked at o2 germany, they handed me
over to a "data specialist", which then told me that those calls are
billed like voice calls, but in the same phrase he warned me to not
"abuse" it - whatever that means...
Data calls are not treated like voice calls within the provider-cloud,
so the provider can distinguish between voice and data calls.
