I wish I could agree but I think we have a long, long, way to go here. I
will point out that the only way Microsoft can phone Cisco is over the PSTN
and that is two of the most pro VoIP companies in the world. Thought I agree
with rate of land lines is dropping in some countries, the rate of  what
VoIP reaches via the PSTN, which is land lines + mobile phones, is growing
in every country I have stats for. Now of course, I'd love to see the PSTN
replaced with something better but I think it is highly unrealistic to think
that is going to happen in less than 10 years. 

RS> And at the rate this discussion is going it is reasonable to assume that
it might be 10 years before RTCWEB might be able to reach consensus. But for
what it's worth the end of POTS/PSTN is under active discussion. If for no
other reason than the  backplanes of the 5E's and DMS 500's are literally
cracking at a increasing pace. Remember 3G mobile networks still use TDM
Switches. Bernard's point is well taken RTCWEB shouldn't worry about
interconnection some gateway or border element will normalize that problem
in some way shape or form.
