Some of my Asterisk-related questions (below) have been answered through my own digging:
- There is a list of Asterisk commands on the VoIP Info Wiki.
- The format of each
exten =>line is
exten => name,priority,application().
- I still don’t know what all the bundled sounds say, but the extra sound files package includes a readme that indicates what all those GSM files contain. This will be leading to the following hilarious dialplan, when I get around to it:
Nobody is available to take your call at the moment. They have been carried away by monkeys.
(sound effects of many angry monkeys)
If you know the extension of the party you wish to reach, dial it now.
To access our company directory, dial 411 or dial zero to leave a message in our general mailbox.
Also, it turns out that the entire O’Reilly book on Asterisk is available for download here under a Creative Commons License. Not that I don’t want to pay for the book — I will, because I believe in such things — but for now, it’ll make a good reference.
