I am looking for someone who is an expert is Asterisk (trixbox) and SQL. I would like a module that can access an SQL database and look for contact information, phone number, and appointment scheduled. then it calls the contacts a day (variable) in advance to remind them about their appointment. Also user can press one confirm, 2 to cancel, 3 to leave a message. an output file should be created and accessed easily. This auto reminder module should be able to call multiple contacts at the same time. it should also detect the sound of a fax and hangup, sound of voice mail and leave a message, a busy signal and try to call 3 times after 120 sec.
I should be able to access controls of this module through the trixbox interface; i should be able to change time of call, how many days to call in advance, and so on...
