What happens when the software's buggy & calls them every 20 seconds for
a day?  (Something to think about, as well - how do I prevent the
machine from going overboard and annoying the recipient of the call?)

I was given a wrong number for a friends' BBS (Bulletin Board System)
once;  My BBS called these poor people, about every 15 minutes, when not
otherwise in use, they finally asked the Telco to ask me to stop
harassing them.  I wasn't even home at the time, was at the now
ex-girlfriends', a couple doors away;  Oops!  This is an "undesireable"
thing, that you don't want to do.  I put the right number in there &
fixed that.

If no busy signal & no fast busy signal, the call probably went through,
to either a human or a fax machine or voicemail or an answering
machine.  (What are you trying to do with your project?)
