I am reading the Asterisk O’Reilly book, and as I’m reading, I have a few questions the book doesn’t really answer.
The book seems to recommend Kernel 2.6 but a lot of the examples talk about 2.4. A lot of Linux distrobutions are shipping with 2.4 right now (Slackware, and I think Debian). Is it worth upgrading to 2.6? So far, the only advantage I have seen in the text for having 2.6 is not having to load that USB daemon.
When running the /usr/sbin/safe_asterisk (I think thats the path anyway), there is an option in the config file to email (NOTIFY) when the system unexpectidly shuts down. Is it possible to email several recipients?
The book talks about 2 ways to sync the data transfer: Digiuim PCI card or the ZTDummy daemon. My guess is that it’s better to use the PCI card to sync because there is less load on the processor as a result. Is this correct? The book didn’t explicity say this so I am just clarifying.
The book descirbes a lot of features that can be enabled to utilize MMX technology. Is it advisable to buy your motherboard/processor combo for the server with MMX in mind?
When used in a corporate enviorment, is it advisable to use PSTN for outside calls (utilizing a FSO interface) or is VOIP developed enough to for use in the outside world? I have only had a VOIP conversation with somebody over a Vonage system. I don’t know what his network topology looked like, but I was not thrilled with the call quality.
Regarding the call start signals (ground/loop/kewl) are any of these compatible with eachother? The book hits that kewl and loop might be compatible, but it never outright says it. When installing a Asterisk system using existing PBX terminals, is it necessary to determine what type of start signalling they use? How is this accomplished?
