Hi all, <br>The problem is solved. I ask the softswitch to send only sdp in INVITE message, then It works. <br>I think sofia doesn&#39;t support multipart content currently. is it right?  <br><br><div class="gmail_quote">2009/11/2 Lei Tang <span dir="ltr">&lt;<a href="mailto:lei.tlfly@gmail.com">lei.tlfly@gmail.com</a>&gt;</span><br>

<div></div>Hi all, I get a  &quot;415 Unsupported Media Type&quot; when FS receiving 
call from a softswitch. I captured some packets, It seems that the softswitch 
use SIP-I protocol, does FS can handle SIP-I message?<br>    <br clear="all">===here is the invite messagefrom softswitch<br>INVITE
