[Freeswitch-users] Stream File on both leg simultaneously

Hi, Is there a way to stream file to both legs simultaneously? I'm trying to play a consent message to both parties before recording a call. I've tried this https://lists.freeswitch.org/pipermail/freeswitch-users/2014-February/103093... without any luck the mux option seems to make no difference. I'm on FreeSWITCH version (*1.10.2-release+git~20191231T140119Z~f7bdd3845a~64bit*) and using XML dial plan to execute commands. It plays file alternatively while the other leg is muted.
