[Freeswitch-users] Outbound calling with recorded message.

[Michael Collins]

Once you have the calls logged into a database then it is a relatively
simple matter to generate the outbound calls using the event socket. The
real challenge (IMHO) is accounting for the outbound calls that don't
actually reach the target, or that go to the target's voicemail, etc.

For the sake of simplicity, let's assume that each person you call will
answer. From there you just need a simple dialplan extension that does a
record app with a specific filename. (You need to match up the filename
recorded with the person you called. You could use <phone_num>.wav I
suppose.) From there it's a matter of launching the calls. I don't do much
with Windows but there are plenty of folks here who do. If you can establish
an event socket connection then you can execute a bunch of "originate" API
calls to generate your outbound calls.

Let's say your dialplan extension for recording the name is this:
<extension name="get their name">
  <condition field="destination_number"
expression="^OB_IVR_Record_Name_(\d+)$">
    <action application="answer"/>
    <action application="sleep" data="1000"/>
    <action application="playback" data="please_record_your_name.wav"/>
    <action application="playback" data="tone_stream://%(1000,0,1500)"/>
    <action application="record" data="/tmp/$1.wav 25 200"/>
  </condition>
</extension>

You can generate a call with this API:

originate sofia/gw/gwname/18005551212 OB_IVR_Record_Name_8005551212

If it works then you'll end up with /tmp/8005551212.wav and hopefully
they'll have given you the info you need.

As for generating these calls, if you don't need something too fancy you
could just use a program written in the scripting language of your choice.
(Perl, Python, Ruby, and PHP are all suitable for this task.) You could also
write "real" program with Visual Studio if that suits you. The key is that
you will need to keep track of what happens when you make all these calls
and be sure not to keep calling them over and over again. :)

I've done this sort of thing with just Perl scripts and it works really
well.
