Actually it's better to spend a few bucks and get a 110 type punch
down tool. Then you can use standard networking patch panels. They
work for telecom needs too and offer another benefit. Should you
eventually decide to go all VoIP you can easily switch them to be
network jacks too.

Despite appearances, this is a non-issue. 'akamai.net' is a
well-known provider of large-scale distributed web-page delivery.
They have server farms "everywhere" (both geographically, and 'on net'
at most major connectivity providers) and "automagically" direct a
query for a page for one of their customers to the server 'nearest'
the query source. This allows for servicing truly enormous numbers
of requests, and for providing fast response to page requests.
Getting SSL certificates 'right' in that environment is really
messy.
***** Moderator's Note *****
If it's too messy, they shouldn't try to do it. A server which is
configured to deliver a default certificate that has no relationship
to the URL it's serving should not offer the service.

At the time a Web server is required to identify itself by certificate
in the SSL/TLS protocol, it has absolutely no idea what URL the client
is going to request. Few servers or clients support the more recent
versions of TLS that allow the virtual host name to be negotiated (and
the servers are, as a general rule, not going to use it until the vast
majority of clients support it).

Then it shouldn't have any SSL certificate at all.

Subject: RJ11 plug strip (Telecom)
Message-ID: <siegman-140312.16214924102009@news.stanford.edu>
Thanks for replies to my overblown earlier question, and I realize now
that what I want is an RJ11 plug strip (or 5 of them) -- in other
words, something that looks and functions exactly like a 110 V plug
strip, except that the cord on one end has an RJ11 connector on it
instead of 110 V plug on it, and the 4 or 6 or 8 110 V receptacles
along its length are replaced by 4 or 6 or 8 RJ11 female jacks, all
wired in parallel.
Except, looks like nobody seems to make such an object, or any
low-cost fully pre-assembled functional equivalent to it. Odd . . .

Not quite what you describe, but close: Radio Shack used to offer
a little 9-inch pigtail device with one RJ11 male (plug) at one end and
a 5-fer at the other -- plastic box housing five RJ11 (female) sockets.
I have one, 's how I know. And, just maybe, perhaps they still do?
Overpriced, of course, but if it's in stock you don't pay shipping :-) .

These pictures (and there are pages and pages of them) may have been
linked before in The Telecom Digest, I personally can't remember.
A fellow telecommunications veteran sent this link on to me. It looks
like people have contributed pictures from their photo albums covering
years and years of telephony history. Included in the photos are a
myriad of products, schematics, system switch locations and system
feature layouts.
Here is the link to the starting page. Hope they bring back memories
to you as they did for me!
