[VoIP] More "Authentic" CNET

[Dennis D Hock]

Well said Keelan.

 Some might argue that CNET needs to be able to replicate the full gamut of
 the original experience, while we seem to be forgetting just how far we
 have all collectively managed to come in the span of a few short years (2
 going on 3 by my count).  Given time and motivation I think the experience
 will most certainly continue to improve and be added to.

It may be that now that we are able to link to each other we have reached a
new conundrum in that what do we talk about and who can we talk to? This is
not much different in my opinion than any other hobby in which much of the
joy and fun comes in the construction.   A case in point being the amatuer
radio operator who linking with some one in another country chats about the
weather and the equipment they each have or the model railroader who builds
mutltiple layouts or continues to build that layout that is never quite
finished.  Some of the fun is in the building.

One last thing as we all have varying memories and fantasies of what the
network is, was, should have been , could have been, the main point I think
is what other commercial company has managed to expand a network so quickly
onto the international scene as this group has?  After all this is all
being done as a labor of love by many who have varying interests in the
many aspects this offers us.

I think we should set back an=t this time of year and reflect on where we
are and how far we have come.

Just my two cents.

The "problem" is that Asterisk passes abstract signaling information
between nodes; "so-and-so dialed 1235, the person at 12345 is busy,
etc." What I'm suggesting is a method of passing very basic state
information (virtual E&M leads) between collectors' switches as
though they were connected via wire trunks (or carrier). If I dial
one of the extensions on a collectors step switch connected to CNET,
I don't hear the switch until asterisk has finished pulsing out the
dialed digits. I may as well be listening to a recording. some
members have even gone so far as to inject canned RP noise into the
connection, just to make things a bit more lively (I suppose).

I was listening to the radio a couple days ago, and a couple
commentators were critiquing TV christmas specials. One of the
commentators brought up "It's a Wonderful Life", and argued against
it on the grounds that it was based on an impractical premise, that
it was based fantasy and lacked realism. The other commentator stated
something along the lines of "This is a holiday where one of the main
events is fat man squeezing down a chimney, to give billions of
people gifts in the short span of an evening, and you want to talk
about practicality and reality?"

The purpose would be more of an academic exercise. The Asterisk CNET
is sterile and predictable. Once you've run through the list of
numbers and listened to everyone's ring-no-answer, asterisk
milliwatt, or busy tone lines, you've pretty much played it out.

If we were concerned about practicality or purpose, we would sell our
switches for scrap and invest the few dollars earned in a mutual
fund. The spare space in our basements could be used for more
practical things like storage.
