[Freeswitch-users] Question about Lua script: How do I detect when someone picks up the phone?

[Mike van Lammeren]

So, I've been reading about early media in the wiki, and have made a little
progress, which leads to more questions.

I understand now why a call is considered connected before one person has
picked up the phone. I am also able to get my script to wait for the phone
to be picked up, by setting the ignore_early_media variable when starting a
new session, like this:

customerSession =
freeswitch.Session("{ignore_early_media=true}sofia/gateway/example.com/" ..
customerPhoneNumber)


After that line, the script waits for the other phone to be picked up.

However, now I wonder what to do with calls that don't complete, get busy
signals, etc.

What do people do in this case? The only related example I can find on the
web is for a javascript dialer, which doesn't address any of these cases.
