[Freeswitch-users] Can I stream a file to a parked call.

Fri Aug 28 13:53:16 PDT 2009

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.
