SMS/Missed Call

[Justin9825]

I'm trying to find a program that will send a SMS to a missed call based on what's inside my calendar. Like I found SMS Notifier. It would look at my calendar and send a SMS with what was in my calendar and when I was free when I missed a call. But It was too bugy and didn't work right and the programmer didn't seem to have any plans to release a new version considering it's been over 9 months since the last version. Does anybody have any suggestions? And yes I did try searching.
