Re: [sr-dev] ICE=force_relay tests between two baresips

Section 4.3, 6th paragraph: The default candidates are added to the SDP as the default destination for media. For streams based on RTP, this is done by placing the IP address and port of the RTP candidate into the c and m lines, respectively. If the agent is utilizing RTCP, it MUST encode the RTCP candidate using the a=rtcp attribute as defined in RFC 3605 [RFC3605]. If RTCP is not in use, the agent MUST signal that using b=RS:0 and b=RR:0 as defined in RFC 3556 [RFC3556]. The sample SDP doesn't include it because it has RTCP disabled.
