But, if telephony over IP, is going to use internet: I assume user will
always be aware of this beacuse of the strange delays that will hear. or
Are you talking about private IP networks for the carriers?

I read(in NASA page)  that there're some studies going on to improve the
QoS features of POS. If POS has comparable QoS capabilities as ATM, may be
VOIP, or using IP networks for other different kind of traffic  will be the
perfect solution? Am I missing some points?????

Thanks in advance fo rthe answers...
