It’s the payload line at the end of the script. If I’m just stupid and there’s a reason for them, let me know.

Thanks again.

Can’t thank you enough for this little gem. Just started in on telephony (for fun and to feed the inner control freak, not professional). I kept looking at SIP providers to give email notification of missed calls, and no one did. So, I changed focus and sought a really lightweight PBX system (initially avoiding Asterisk) that had the feature. Alas this post of yours was about the only promising hit, so I spent a few days learning enough Asterisk to figure out where to plug your script in. It was a fun learn. I really fell for Asterisk in the process, and still think your script is just elegant and impressive — surpising the Digium team left this out.

Thanks again, friend.
