My setup is as follows:<div><br></div><div>FreeSWITCH -> SIP Trunk -> PSTN.</div><div><br></div><div>From freeswitch, I'm making outbound calls using event socket via the "external" profile. Except for the ext_rtp_ip and ext_sip_ip, everything is default settings. Using "playback" application, I'm playing a mu-law audio. I'm also starting the "vmd" application, so that I can replay the message on beep.</div>

You would have to have raw headerless data in a .PCMU file for it to play native.<br>
<br>
Can you elaborate on your setup a bit more?<br>
