<br>
Check the 2 first bits of the raw rtcp packet, it is where the version is set (<a href="http://www.networksorcery.com/enp/protocol/rtcp.htm" rel="noreferrer" target="_blank">http://www.networksorcery.<wbr>com/enp/protocol/rtcp.htm</a>).<br>
In your case, it looks that the 2 bits are set, that's why you are getting 3. Are you sure it's the same packet for which you are seeing version = 2 in wireshark?<br>
<br>
It would be really interesting to check the version on each rtcp packet from the call to validate that some are indeed incorrect.<br>
<br>
But if you are willing to accept the bad version, you can apply the following patch (beware, it's a non tested hack):<br>
<br>
diff --git a/src/switch_rtp.c b/src/switch_rtp.c<br>
index 0ae3b641f0..fe975aca32 100644<br>
