Ah, well, that's where you're trying to change the way that things have been done for some decades. Ringback has historically been generated close to the called party, which is why you hear different ringback if you call people in different countries.
What's wrong with that? Isn't that what we are all doing (or trying to do), to some extent?
International dialing very well may use different ringbacks but:
1) How important is this, really? 2) How much more complicated is adding at least the real potential for 180?
The actual ringback tone may not be important, but many other supervisory indications may occur at that point, either as tones or as voice announcements. E.g. call a cellphone that has problems - out of range, out of service, etc - and you will probably get a voice announcement telling you want's up. Steve
