Tell that to Dean :) He thinks it is not routable (that's the point I was trying to make).
Warning: this needs NOT to be true and IMHO this part of
the informational section is misleading. In section 5.1.4 Local numbers
it is clearly stated:
"There are two ways to label the context: via a global number or any |
number of its leading digits (e.g., "+33") and via a domain name, |
e.g., "houston.example.com". The choice between the two is left to |
the "owner" of the local number and is governed by whether there is a |
global number or domain name that is a valid identifier for a |
particular local number.
|
The domain name does not have to resolve to any actual host, but MUST |
be under the administrative control of the entity managing the local |
phone context. "
Since the domain name does not have to resolve to an actual host,
one cannot rely on this, so your statement may be wrong.
