<div dir="ltr"><div>Hi,</div><div><br></div><div>I've been using Freeswitch as a PBX, and I'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 "sofia.c:1431 nua_i_media_error: unknown event 22: 988 Incomplete offer/answer" and the call is rejected.</div>
<div><br></div><div>I think Freeswitch is getting upset with the a= line after the "m=video 0" line because there'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?</div>
