[VoIP] Numbering

[Mark Rudholm]

Greetings, I'm not presently a member (don't have any vintage switchgear)
but know of cnet through a friend who is a participant.

I run a couple of Asterisk installations, and am thinking about numbering
options, particularly for interconnecting multiple Asterisks.  I'm looking
at various ways to direct calls off a switch, such as fake Feature Group D
dialing prefixes, or fake NPAs, or simply assigning portions of internal
numberspace to a given external switch.

In any case, I figured I'd read through the mailing list archives here to
see how cnet has solved the problem.  For some reason, I was under the
impression that cnet was using 311 as an NPA, but I guess that isn't the
case and individual members must simply be integrating cnet numberspace
into their numbering plans in various ways they devise personally.  Or
just aren't integrating PSTN and cnet numberspace.

How are folks doing this?  Or are they?  For cnet, it seems like using
an nonassignable "NPA" like 311 would make sense, since it would let you
seamlessly integrate cnet numbers into the PSTN dialing without
collision problems.

The mentions of ENUM also piqued my interest.  Is cnet running an ENUM
DNS server somewhere?  It'd be neat if it was actually under
1.1.3.1.e164.arpa. or some such.
