I did check ice rfc 5245 and didn't find such requirement. Word "rtcp"
does not exist in the rfc and its ice sdp example does not include rtcp
o=jdoe 2890844526 2890842807 IN IP4 10.0.1.1
c=IN IP4 192.0.2.3
m=audio 45664 RTP/AVP 0
a=candidate:1 1 UDP 2130706431 10.0.1.1 8998 typ host
a=candidate:2 1 UDP 1694498815 192.0.2.3 45664 typ srflx raddr 10.0.1.1 rport 8998
Where did you find the requirement? Is it in some other rfc?
