In asterisk dial command A(x): Play an announcement (x.gsm) to the called party. is available to play some message to b-leg and still keep a-leg hear ringing tone.
In freeswitch i tried
_nolocal_execute_on_answer=playback <file>
and
bridge_pre_execute_bleg_app=playback
bridge_pre_execute_bleg_data=<file>
I get initial ringtone before bridge. But then after b-leg asnwer, A-leg gets only silent audio until the audio file gets completed on B-leg. How do i make it such that A-leg still gets ring tone, while there is a message being played only to B-leg? Your suggestion might help me a lot!
group_confirm_file is the best option for playing a message to callee before bridging the call to A leg
<action application="set" data="group_confirm_file=playback /path/to/prompt.wav"/>
<action application="set" data="group_confirm_key=exec"/>
