You Don't Know Jack about VoIP

Posted by michael on from the single-purpose-phone-lines-so-old-skool dept.

gManZboy writes "Phil Sherburne and Cary Fitzgerald, two senior technologists over at Cisco, have written an in-depth overview of VoIP for developers and the like (not for everyone who's ever used a phone). Like Queue's earlier You Don't Know Jack about Disks, this article covers the history, the basic technologies, how they work, and where they're headed. If you found the blog post yesterday lacking, check this one out."

  2. Test your connection... by fiji · · Score: 5, Informative

    Before you waste time trying to get VoIP (or paying for VoIP from a provider) going it is worth testing your connection to see if it can support VoIP calls at a reasonable quality. You might want to test your line at various times during the day... I get crappier calls in the evening.

    Anyway, http://testyourvoip.com/ provides a decent free testing serice just using a web browser.

  3. Which service is better? by exhilaration · · Score: 4, Informative

    If you're in the market for a VOIP service, Geekbooks did a pretty decent comparison of different services. Does anyone have any other links?

    Your comment sounds pretty interesting, since you seem to know what you want, but apparently haven't looked anywhere other than Cisco.

    Avaya's IP telephony products provide your encryption, Cell+Wifi with auto switch over, and my favorite, all the servers run GNU/Linux! No video phones yet.

    I hear they're really expensive, but I really don't have any clue as to that, I just fix the stuff.

    Yeah, Primus VIOP is only $20 /m when whith Telus it's at leas $30 /m for basic service. Plus you can have a extra line for $4 extra that you can place anywhere in Canada. So even though I live in Edmonton I could have a local number in Toronto that I could make local calls to there from. Also people could call me on that line locally and it would ring here in E-town.
