<p>Hello,</p>
<p><br>
</p>
<p>By default, Freeswitch seems always translates incoming SRTP packets to outbound RTP only packets as the INVITE SIP message to Receiver from FS contains only RTP/AVP audio media in SDP section even if the Caller's INVITE has RTP/SAVP audio media only.

<p>Is there a way to let FS send SRTP packets to receiver as the receiver can accept SRTP media only?</p><span class="HOEnZb"><font color="#888888">
