Hi all,

We've developed an application internally using version 498:8901.
After deploying on the clients' system (using version 9288), playback
doesn't work any more and the call is bridged straight away.


*** I notice the following error in freeswitch.log:
2008-09-03 05:35:00 [DEBUG] switch_core_state_machine.c:140
switch_core_standard_on_execute() sofia/external/18288363200@jnctn.net

media! pre_anyswering channel sofia/external/18288363200@jnctn.net


*** The dialplan:
<document type="freeswitch/xml">
<section name="dialplan" description="FreeSwitch dialplan">
<context name="default">
<extension name="westhawk">
<condition field="destination_number" expression="^8007788821$">

<action application="bridge"
data="sofia/gateway/westhawk/16262435322"/>
</condition>
</extension>
</context>
</section>
</document>


I searched for the error message, but couldn't find anything.
The wav file exists.
Playback works on our internal system.
On our internal system (Suse 10.0, x86_64 GNU/Linux), calls come in via
Asterisk over SIP.
On the clients' system (Suse 10 enterprise, i386 GNU/Linux ), calls come
in via JunctionNetworks over SIP.

I have two other scenarios where playback and bridging is done in
javascript. This still works, see:
<js>
var bridge = null;
var play_jingle = null;
var recordfile = null;

function dummy(session, type, data, arg)
{
}

if (session.ready())
{
bridge = argv[0];
play_jingle = argv[1];
recordfile = argv[2];

session.answer();

// start recording
session.execute("record_session", recordfile)

if (play_jingle == "true")
{
// play 'general' jingle
session.streamFile("westhawk/Jingle.wav", dummy);
}
// play 'record' jingle
session.streamFile("westhawk/call_recording_tag.wav", dummy);

// bridge the call to the merchant
session.execute("bridge", bridge);

// hangs up and closes session
exit();
}
</js>

(Oh, before any one asks or if interested, this js was created because I
couldn't get recording working for the b-leg by using a dialplan without
js. It only recorded the incoming leg, but recorded silence after bridging.)


Does anyone know what the "Application playback Requires media!" error
message means and how to fix this problem so playback works?

Thanks, Birgit

Can you describe a bit more about the recording issue? Playback does
require media so it pre_answers the channel (ie starts early media).
Its not an error its a DEBUG notice that lets you know "Hey you're
trying to play a file so for that to work we have to pre-answer the
channel otherwise this won't work".

Can you show me an example of how you used the record_session and only
recorded one side of the call?

Hi Brian,

Thanks for your help.
I'll get back to you about the recording issue later, thanks.

My immediate problem is that I don't hear the playback. I only hear
ringing until the answerphone of the person on the other side of the
bridge answers.

I'll include more of the log file, maybe that gives you a clue.
The jingle is about 4-5 seconds long.

How about you put a "ring_ready" before the playback.

Hi Brian,

Thanks for your answer.

Page
http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_ring_ready
doesn't really tell me very much about what
<action application="ring_ready" />
does.
Does this "just" stop the ringing?

Do I need by any change to "answer" the call as well before I do playback?
So:
ring_ready
answer
playback
bridge
?

That's what I do in javascript ( session.answer(); ).

Thanks, Birgit
