I’m still old school enough to think that voice conversations still matter. So I call people, and they call me. When I’m out and about I like to know who has called me back at my office (no I don’t want my cell to ring EVERY TIME someone calls my home number, my cosinity number or my home office number). That way I can see who it is and give them a ring right back if it was really something we needed to discus.
I’ve had a number of solutions in place for this over the last 2 years or so. From IM messages to SMS messages. The problem with IM is the lack of great notification on mobile devices. The problem with SMS is paying 2-5 cents each.
This led me to think – maybe using Twitter and @ messages or DM’s was a better answer.
Before I give you the code let me first explain how this works. If you are not comfortable with Asterisk, Asterisk AGI, and customizing extensions.conf you should probably stop here.
