What a day — Rogers’ network was b0rked starting around noon, which meant that our office T1 connection flapped up and down all afternoon. It finally seemed to give out entirely around 4 p.m., at which point I think everyone at the office just headed home. Since I have my name on a ticket with Rogers, I’ll definitely be asking for a refund per our SLA.
Matt, a former colleague of mine, told me that Bell had been advertising null routes in the morning too — not good. In general, not a good day for Canadian ISPs.
In other news, I’m working on the Asterisk VoIP server again. As I build and configure this thing, I think it’s best if I keep a list of questions that I will try to answer as I progress. Here’s my current list of questions. If you are an Asterisk guru and happen to know the answers to these, feel free to comment on this post!
- Actions in the dialplan are usually applications. Where does one find a list of these applications (and what they do), short of doing a
show applicationsat the Asterisk CLI?
- What is the syntactical format of each
exten =>line in the dialplan? (I know I’ll probably come across this somewhere in the docs, eventually)
- How do I register phones — either softphones or physical IP phones — in Asterisk, and how do I get those phones to authenticate to the Asterisk server to self-register themselves? Is there any way to autoregister phones with a restricted dialplan?
- How do I know what all the sounds bundled with Asterisk say, short of playing them one-by-one?
- How do I configure the voicemail system to do things like e-mail voice messages to the mailbox owner, encode the voice mail in different formats like Ogg Vorbis or MP3, and so on?
I plan to post the answers in this journal when I find the answers.
