I read several chapters in TFOT. Several times.
I examined the Asterisk Glossary (for which thank you btw, although it’s missing 90% :^) asterisk.org/glossary).
I try to keep it poked in under my skull long enough to take a peek at the .conf files to see if I can match what I see there with concepts in the book.
Most of the HowTos I’ve read concentrate on three of them: sip.conf, extensions.conf, and voicemail.conf, so so do I.
But it’s like a spell gets cast when I open the files and my brain jellifies. Terms fly around like Indian clubs and medicine balls.
Compounding the effect is my ATA (I think), a Linksys SPA-3102, which has a lot of these same terms flying around inside its web configuration, but most of which have been dumbed out so it can pass the stuff on for Asterisk to do the heavy lifting.
So Most of the stuff in the SPA I should ignore but ~Some~ of the fields entered in the SPA Must correspond EXACTLY with fields in the Asterisk confs, and–with the jargon soup–a newbie is soon reduced to flailing around.
Could some kind soul, compare and contrast the following terms for me, as you would for a sixth grader, some of whom I daresay have already had better luck at this? :^)
Q. What’s a trunk? Do I really need one?
Q. What’s a route? Do I have to have one of those?
Q. What’s an extension? When do I need more than one? Any?
Q. What’s a channel? (I think I know this one: I might call it a “conversation” and say it’s the thing that happens when the Caller finally gets connected to someone or something.)
What would be most useful would be a sentence or two to create a picture in my head.
For example, (have to be careful here or people will google the wrong answer for a millennium):
I hope someone can imagine how far this could go to setting up the room for new users to arrange the rest of the furniture as they continue to read and study.
I could always return to my little shibboleth to force the concepts back into their proper relationships.
If no help, I’d happily enjoy sympathy.
