No. ISDN is a computer networking technology. It really is. When you swipe 
your credit card, it uses the D channel of ISDN to deliver the numbers to 
your bank and get the auth back. It's digital. It's computer. It happens to 
be common that you take those bytes and run them thru a DAC to a speaker. 
That doesn't mean your phone isn't a computer.

And telco numbers are managed by ISO, and then each country, then each 
company, then each local office, because the telco has *way* too many phone 
numbers and crosses *way* too many administrative domains to make it 
reasonable to only have two levels of network allocation.

IANA allocates blocks to Tier 1 providers. Then *they* split up the blocks 
smaller and smaller. IANA has no say in what /24 you wind up getting on your 
individual cable modem.

And that's the problem. It's a replacement, not an upgrade.
