Hi there,

I know there are other ways of doing this. I am just trying get to
know have fun with the FreeSWITCH API.

I am using originate and park a call:

fsApi.Execute("originate",
string.Format("[origination_uuid={0},origination_caller_id_number={1}]sofia/gateway/broadvox/{2}
&park", blegSession.Uuid, OutgoingCallerID, NumberToDial));

That works great, the phone rings. I want to play something to this
called party when they pick up.

while (!blegSession.answered())
{
Log.WriteLine(LogLevel.Alert,
"Inside::CallReturns:!Session.answered::Loop");
blegSession.sleep(500, 1);
}

string promptFile = "prompts/whisper.wav";
blegSession.StreamFile(promptFile, 0);


This works - but the audio is choppy and slow.

Is there something I need to do to that parked call before streaming that file?


Thanks for any input.

Phil

try wedging {ignore_early_media=true} before the first [ in your dial string
and eliminate the code waiting for answer.

thanks for the reply.

Tried this and exactly the same result. The prompt is slowed - as if
the person is drunk.

I do notice that the originating call SDP shows:

a=rtpmap:0 PCMU/8000

but the play tries to use:

EXECUTE sofia/external/6093693828
playback(prompts/press-1-to-accept-call-from.wav)
2009-08-28 16:03:14.507375 [DEBUG] switch_ivr_play_say.c:1097 Codec
Activated L16@8000hz 1 channels 20ms


Should the codec be PCMU@8000hz as opposed to L16@8000hz? If so of
there a way of forcing this codec for play.

Thanks


Phillip

the L16 codec is used because the wav files is raw PCM audio
which is being encoded to PCMU

Have you tried doing this to a locally registered phone?

nevermind,

I didn't look closely at your code.

how did you end up with blegSession ?
Are you running this script from the CLI or via the application interface.

The dialplan is is kicking off the C# script:

<condition field="destination_number" expression="^(12125553666)$">
     <action application="managed" data="MyFSProjects.ProcessCall"/>
</condition>

I launch a thread and specify the uuid to originate:

fsApi.Execute("originate", string.Format("{{ignore_early_media=true,absolute_codec_string='PCMU'}}[origination_uuid={0},origination_caller_id_number={1}]sofia/gateway/broadvox/{2} &park", call.Uuid, call.OutgoingCallerID, call.NumberToDial));

in the callback i try and play the wav file:

FreeSWITCH.Native.ManagedSession blegSession = new FreeSWITCH.Native.ManagedSession(callID);
           
if (blegSession.Ready() && blegSession.mediaReady())
{
      blegSession.Answer();
      blegSession.Execute("playback", "prompts/press-1-to-accept-call-from.wav");
}

I go on to bridge the leg a and b - that bits works fine.

Taking over the session while it's parked like that from your code and asking it to play a file is making it do 2 things at once.
The session's thread is already busy in the park loop so you would have to change it's state to something passive like soft_execute so
it's thread was not doing anything or send it a message so the park loop would pick it up by using the uuid_broadcast app::arg

there are variables you can set that begin group_confirm_* that you can set to do this all without even using a script.

That makes perfect sense - I now send the call to a managed app instead of park and every thing works great. thanks.
