I don't believe this is possible. If you record 5 seconds of silence into a file you might be able to use file_string:// to play them both. /Peter -----Ursprungligt meddelande----- Från: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Emrah Skickat: den 22 augusti 2012 16:24 Till: FreeSWITCH Users Help Ämne: [Freeswitch-users] Concatenated multiple playback types Hello there, I am trying to add some silence before the alone sound file in my conference.cnf.xml and can't get it to work. Here is what I tried: <param name="alone-sound" value="silence_stream://5000!file_string://conference/conf-alone.wav"/> <param name="alone-sound" value="silence_stream://5000&file_string://conference/conf-alone.wav"/> <param name="alone-sound" value="silence_stream://5000|file_string://conference/conf-alone.wav"/> <param name="alone-sound" value="silence_stream://5000;file_string://conference/conf-alone.wav"/> Any idea on how to do this? Thanks!
