[Freeswitch-users] Concatenated multiple playback types

[Emrah]

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!
Emrah
