		<title>Asterisk &#8211; Using CallerID to make decisions</title>
		<description><![CDATA[CallerID information is carried along quite readily within the SIP protocol; most SIP providers pass that along to their customers for free. Other than just showing it as "This is the number the call is coming from", can we do something more useful?
Absolutely!
As an example, imagine the contexts incoming (where calls go to when they [...]]]></description>

		<title>SAGE-AU Presentation</title>
		<description><![CDATA[I did a presentation to the SA chapter of SAGE-AU last night - the first presentation I've given in a very long time!
Download the slides here
Overall, I think it went pretty well - it didn't seem too obvious that I hadn't had a chance to practice the talking that went with the presentation, and only [...]]]></description>

		<title>Hacky IP forwarding with IP aliases and SSH</title>
		<description><![CDATA[We interrupt your regularly scheduled broadcast of quality sysadmin programming to bring you a brief announcement on using SSH and hacky port forwards to access something via a LAN IP over the Internet.
If I have a server at home that can _only_ be accessed via 192.168.1.12 (say) - perhaps because it is a web application [...]]]></description>

		<title>IPv6 is BORING!</title>
		<description><![CDATA[Please note that this is all personal opinion, and is not a reflection on the opinion, or policies, of any employer, past, present, future, or comma-less.
What is IPv6?
IPv6 is the next step after our current IPv4 addressing scheme - and not a lot more. Instead of the we-thought-it'd-be-ample 2^32ish addresses, we get the it'll-be-enough-this-time-for-sure 2^128ish [...]]]></description>

		<title>Community Based Alerting</title>
		<description><![CDATA[There are so many ways to monitor whether a particular application is working properly or not. For the average website - Is the server pingable? Can you open a socket to port 80? Can you do a GET request and get a "200 OK" response?
Some checks are more complicated again - "Does the page '/index.php' [...]]]></description>

		<title>Asterisk &#8211; Specifying outbound routes for fun and profit</title>
		<description><![CDATA[...or at least a little savings.
You're in a quandry. You've found VSP1, with brilliant general rates. VSP2 has fantastic rates for mobile calls. VSP3 has the cheapest calls of all to England, where you have family. You can't use just the best bits of each... can you?
With Asterisk, yes you can!
The extension configs here assume [...]]]></description>

		<title>Asterisk &#8211; Email notifications</title>
		<description><![CDATA[One of the things I like about Asterisk, is its ability to send email notifications to me if certain things happen. There's no built-in ability to send emails by itself, so we'll use its integration with the underlying server to do it.
Let's start by sending me an email if someone uses my VoIP line to [...]]]></description>

		<title>Asterisk &#8211; Dual-dialling to save money</title>
		<description><![CDATA[Asterisk saves me money, even using just the one VoIP provider. (Disclaimer: The provider I use is run by my employer, but I'm writing this only as a happy customer! :).
It just so happens that my work desk phone number is a free call, but my wife can never remember the number and is usually [...]]]></description>

		<title>Plain-text password storage is good</title>
		<description><![CDATA[...or at least, not as bad as it's sometimes made out to be.
Please note that I am not discussing any password system used by any employer, past or present. This is based on general industry knowledge only, and is meant to explain why so much software suggests or requires plaintext passwords to be stored.
When I [...]]]></description>

		<title>Asterisk &#8211; Database-driven CallerID</title>
		<description><![CDATA[One of the nice things Asterisk can do is manipulate Caller ID information on the fly. Since I'm too lazy to update the stored numbers within my individual cordless handsets, I use Asterisk to cheat. Asterisk looks up the incoming phone number ("08XXXXXXXX") in a MySQL table, finds matching text ("Bob") and passes that along [...]]]></description>
