Well, if you caveat it that way., then your statement is correct. One  
might reasonably ask if those operators don't simply have their  
requirements confused.

My take, however, is that "early media" is a cop-out for coping with a  
fundamentally broken PSTN-interworking model, coupled with Bad Ideas  
about charging based on signaling rather than content.

But like forking, this genie has left the bottle, and we have to deal  
with the consequences of that failing as long as we have SIP 2.0.
