Here are my submissions:
I have an extensive network made of a lot of wireless bridges and routers including a few solar powered so there’s a lot that can go wrong. I made a bash script (that Asterisk calls) that pings specific addresses in a specific order to find out where the problem on my network is (if there is one). It then copies the appropriate sound file onto the results file which asterisk plays. So, I just dial “net” on my phone and I get an instant answer as to what’s wrong.
I’ve done the script where it downloads the weather and converts it to speech. It’s here: voip-info.org/wiki-Asterisk+cmd+Festival
Post your cool ideas!
