&gt; Hi,<br>
&gt;<br>
&gt; I&#39;ve been using Freeswitch as a PBX, and I&#39;m having problems when making video calls when the video stream is rejected. The other endpoint (happens on 4 distinct endpoints) sends back a m= line with port 0, and an a= line with codec type as /0. When this happens, I get the error &quot;sofia.c:1431 nua_i_media_error: unknown event 22: 988 Incomplete offer/answer&quot; and the call is rejected.<br>


&gt;<br>
&gt; I think Freeswitch is getting upset with the a= line after the &quot;m=video 0&quot; line because there&#39;s no codec name. The RFC says that any a= lines after an m= line with port=0 must be ignored, is this a bug?<br>
