[sr-dev] git:master: RTPProxy: Documentation improvements

[Carsten Bock]

Hi Ovidiu,

that won't work, since you would have to call rtpproxy_manage("IE")
for the request and rtpproxy_manage("EI") for the reply.
Since this flag will check for IPv4/v6 in the SDP, the reply would
send "IE" for both request and reply.
