Steve,

Yes but this I-D is not just for voice (e.g., could be for messaging
services such as SMS, MMS and IM).

A mobile operator may include this specific NAPTR RR to contain the IMSI
or MCC+MNC information in Carrier/Operator/Infrastructure ENUM
environment.  It can also be used in private ENUM offering before
Carrier/Operator/ Infrastructure ENUM is deployed.

It is my understanding that MCC and MNC are used _between_ mobile
service providers when subscribers are roaming to ensure that
operational agreements exist that allow service to be extended to that
subscriber in the visited network. Calls are completed based on the
E.164 number dialed.

There is a lot of sensitivity over more public use of these data items.
