The other evening I busied myself with tweaking Asterisk to do some more geeky things. One such item was where I configured it to send a message to my Jabber account every time there was a call to a particular extension. Great for call logging, integration, and general user friendliness. If I was so inclined, it could message a Yahoo, MSN, ICQ, or AOL account through the Jabber platform to inform me of a new call. How rather flexible.
