Subject: Re: [Freeswitch-users] Use of ESL and PHP for Call
Shahzad,
I think you may have taken an unnecessarily complicated approach to this.
If I were you I would simply use the play_and_get_digits application which
does all the work for you. I would also handle that in the XML dialplan and
then use the api_hangup_hook to call your script to process the result.
(I.e. did the user press 1 or 2 or something else...)
I recommend you start with something simple like a basic originate command
that calls the user and then drops that call to a dialplan extension:
originate user/1500 meeting_request_1500
Then create that extension:
<extension name="meeting request">
  <condition field="destination_number" expression="^meeting_request_(
\d+)$">
    <action application="set" data="target_user=$1"/>
    <action application="set" data="text=cepstral|callie|Hi, we have a
meeting on Monday at 9, are you joining us, if yes then press, 1. and if
not press, 2."/>
     <action application="answer"/>
    <action application="sleep" data="1000"/>
    <action application="play_and_get_digits"
      data="1 1 3 5000 # speak:${text}
ivr/ivr-that_was_an_invalid_entry.wav answer \d"/>
    <action application="set" data="api_hangup_hook=system handler.php
${target_user} ${answer}"/>
     <action application="log" data="INFO User ${target_user} responded
with ${answer}"/>
    <action application="playback" data="ivr/ivr-Thank_you.wav"/>
    <action application="hangup"/>
  </condition>
</extension>
Then you just need to write your handler.php script (or whatever you want
to call it) and have it parse the command line args - the first one is the
user and the second one is the digit pressed. PHP scripts will work for
hangup hooks but they aren't the best choice since there isn't a "mod_php"
like there is a mod_lua or mod_perl. Those modules let you do cool things
like "session_in_hangup_hook." However, what you're doing doesn't look like
it's very difficult so the example I've given should get you going. Please
note that I just did this off the top of my head w/o testing it so be sure
double-check everything if you run into any unusual or unexpected behavior.
Keep in mind that in this example you will need two different PHP scripts
- one that actually initiates the ESL connection and does the originate and
one that handles the call results. Instead of one semi-complicated script
you will have two very easy scripts.
Hope this helps...

Subject: Re: [Freeswitch-users] Use of ESL and PHP for Call
You should pass the originate command to &park() instead.
Right now you originate the call and then execute the application speak.
After this (when speak is finished) FS has no more instructions so it will
hangup the call.
If you execute &park() instead, the call will be "parked" and wait for
furter instructions. Then you will also need to execute the speak from ESL
instead - and afther that you continue to do whatever you want to do with
the call.

Try this in your dialplan before sending the call to the conference:

When I press cellphone's key, although Freeswitch can't see this DTMF,
but the the other participant of the conference call can hear my DTMF tone.
Does this situation indicates that the DTMF tone has been forwarded by SIP
provider's server?

 This is because Apple Deprecated SSL on Lion... They don’t want you
using it...
Configure ‘--without-openssl’ and the problem goes away...
There is an open jira on this issue I just cant recall the bug number off
