[VoIP] Number portability in CNET

[Steph Kerman]

How does this fit in with David's comment?

If the full 7-digit number is looked up in ENUM for each call to allow 
sharing of office codes doesn't that require ENUM to be updated for all 
new line assignments at local switches?  I thought only the 3-digit 
office code was being looked up and that there was discussion about 
extending this to the thousands digit to allow sharing of office codes 
in blocks of 1000 numbers, but that it had not been done.
