As for a list of companies that are participating in any registry, it's
something I've yet to see anywhere.
i tried last week to call a u.s. 800 number using
www.e164.org and
freenum.org enum, which both point to
tf.voipmich.com. in summary: it
was impossible to get connected. looks like their gws are full or
broken.
a service like that has to work reliably or it is good for nothing.

You're right. The gateway parsing 1-800 (and other toll-free US
numbers) is not accepting connections. I've notified the owner of
the gateway, and hopefully we'll see it back on-line shortly. In the
meantime, I've commented out those gateways.
The
freenum.org site relies on the kindness of gateway operators to
keep the system running, and I need to put some test cases in there
to periodically test connectedness, I suppose. I have some test
numbers in each nation that has a gateway, but I don't have any
automated way of testing it other than seeing what SIP messages I get
back. I suppose the best possible test would be a toll-free
destination that constantly sends a DTMF sequence so I could match
against it with an automated Asterisk process...
While I agree that the
freenum.org gateways have to be functional for
these services to be useful, I would also say that their use is
currently "optional", so a failover plan should always be in place at
the originating gateway end. Due to the volunteer nature of the
project, it is probable that some gateways are full or off-line, so
having multiple ENUM replies back at the same priority level would be
nice, so that the query would have multiple answers through which the
originating gateway could cascade. In the worst case, a failed SIP
lookup should just send the call out the usual pathway (PSTN? Paid
SIP transit? ...) to the destination.
VOLUNTEERS WANTED: Anyone who has spare capacity on their gateway
(at least 15 trunks for +1, but any number of trunks >3 for any other
nation) is encouraged to contact me off-list to set up an NAPTR entry
in the zone for their nation. This is a for-free effort, and there's
no obligation other than to give "best-effort" to terminating calls
into the toll-free number ranges for your nation.
