[Freeswitch-users] Freeswitch streamFile when the user answers

[Michael Collins]

Also, the other question is this: do you *need* early media? If not then
Darren's suggestion is definitely the way to go. Note that if you ignore
early media then all calls that fail will show up as a NO ANSWER. If this
doesn't work for you then ignoring early media is not an option, in which
case there simply is no perfect way to do it and you just have to make the
best of it. What I've done in the past is something like this:

originate openzap/1/a/5551212 825551212

Then I define an extension that matches on ^82(\d+)$ and does something like
this
<action application="pre_answer"/>
<action application="set" data="execute_on_answer=transfer IVR_ANSWER"/>
<action application="sleep" data="20000"/>
...handle non-answered calls

Then I define another extension that matches on ^IVR_ANSWER$ and does
something like this
<action application="sleep" data="500"/>
<action application="ivr" data="my_ivr"/>
...etc...

The idea for me is to handle the different scenarios I might face when
dialing. At the very least if the call goes unanswered then I have the
hangup_cause variable that tells me if it was busy, no answer, invalid, etc.

Hope that helps.
