FYI, ENUM concept to let callee side, who won't pay calling fee,
determine the internet-PSTN gateway is broken from the beginning.

Telcos managing telephone numbers of callees will, as a default
gateways of callees, choose the most profitable (which is likely
to be unnecessarily expensive to callers) gateway for the telcos
and callees will be uninterested in the choice.

ENUM could be fixed, if access telcos only are allowed to be
delegated ENUM records and the telcos are forced to have gateways
from which all subscribers of the telco can be reached at least
expensive rate.

Still, ENUM is not a very interesting concept.

True.

Just as PSTN does not need public IP addresses, the Internet does
not need E.164 addresses.
