Candace,

It's a fine opinion (and I appreciate your sharing it).  However, I
don't fully understand it.  In particular, if you are an opponent of
SIP.edu taking on the "by numbers" problem, of what are you a
proponent?  Continued development of the cookbook and growth of URI
reachability?  An asserted identity testbed?  Building a cookbook
model for supporting open UA registration?  Something else?

Also, you state that "SIP.edu by Numbers cause(s) more problems than
it solves".  Just to be clear, the problem solved is that of reaching
SIP endpoints from devices that have only 12-digit keypads.  So what
problems do "by numbers" solutions cause (besides the opportunity cost
of spending "so much effort")?

My sense is that it is not really so much effort.  John Todd has a
good proposal that is almost baked.  We need to create a non-profit
organization to run the ITAD root.  Then, each domain needs to bring
up a local ENUM.  Since most domains are already managing numeric
identifiers, the local ENUM can simply re-write to
sip:<5-digits>@local-gateway.  That doesn't seem so bad, but maybe I'm
missing something.

Best Regards,
