The Changelog

I work in an open-plan office. Normally I like to listen to some of my iPod's music, or NPR or something, at some point during the day. It helps me tune out distractions when I'm coding or concentrating on something. My iPod, and my nice Etymotic headphones, get transported to and from work each day in my laptop bag. Today I forgot the laptop bag at home.

What to do? I could just work without headphones. I'd be fine, but you know, I've got standards here. My job involves working with computers, so I ought to be able to come up with a workaround, right?

So lesse... what do I have? One binaural (mono sound, but speakers for each hear) telephone headset. One Polycom SIP phone, connected to our corporate Asterisk system. One workstation with sound capabilities. One installation of Asterisk on this workstation for testing purposes. And, a pre-existing path from the corporate system to the workstation system for testing Asterisk. (Very handy that, and used a lot when we were doing active Asterisk work.)

So in less then five minutes I had music going via my telephone headset. Lo-fi, and not noise-dampening like the Etymotics, but I enjoyed it for the simple fact that it was being played *over the phone* at no cost to anyone. My desk phone supports multiple "lines", so I still could place and receive calls just fine.

Should anyone care to look, they'd find a 5-hour call from me to myself deep in the Asterisk logs. My own workstation logs will show that I put myself on hold for 5 hours (since I used Asterik's music-on-hold feature to play my own selections).

IP telephony is fun. So is Asterisk.
