Subject: Re: [Freeswitch-users] Ringback, MOH or file playback while executing dial plan instructions

In case you want to customize the ringback for each caller, see the link below (Anthony did a great job making timeout work as needed). I use it for every caller. I have a LUA program that dynamically builds the sound stream and adjusts the length of the music. https://wiki.freeswitch.org/wiki/Mod_local_stream#Execution_Parameters

Yes of course. I’m not even trying to play a sound file. A ringback would be fine for what I’m trying to do.
Let me rephrase. FS isn’t generating any ringback unless I execute a bridge somewhere. This isn’t useful in my case. I’m trying to have the caller hear something while FS keeps executing the dial plan.

Something like:
<action application=“answer” />
<action application=“playback” data=“please-wait” />
<action application=“ring_ready” />
<action application=“sleep” data=“50000” />
<action application=“hangup” />

Hope this helps you understand my issue a little better.
