We are not using Bridge. we are using ( event socket ) bgapi originate <call_url> &park() to start the call. after that we wait the background_job event and take the ID of the session and use it to pass playback commands on the line. sebastien From: freeswitch-dev-bounces@lists.freeswitch.org [mailto:freeswitch-dev-bounces@lists.freeswitch.org] On Behalf Of Brian West Sent: 10 septembre 2008 11:46 To: freeswitch-dev@lists.freeswitch.org Subject: Re: [Freeswitch-dev] Chunky sound in wav file using Record_Session with RECORD_STEREO=true So its a single leg call.. where you're playing a file to a user?

Freeswitch send the calls to a SIP Gateway using SIP/RTP. This SIP Gateway communicate with a PSTN using T1 lines ( DMS-100 ) . As soon as the call is connected, leg B play waves files ( playback command pass by event socket ). Leg A is the customer, and can be anything ( somebody listening to the call, Voice box, etc ). sebastien Brian West sip:brian@freeswitch.org
