It depends on the configuration.
IMO a "correct" kamailio/rtpproxy setup uses (note: 'a' implies
'r'):
Alice Atlanta Biloxy Bob
rtpproxy rtpproxy
flags flags
<---''---|--'a'--> <--'a'--|------->
This is because Atlante can not know about the setup of Biloxy (if the
clients are behind, if there are multiple proxies in between). Thus, a
proxy should perform NAT traversal (rewrite contact untrusted SDP) only
for the local users. For external users (other domains) the Atlanta
proxy should not rewrite the contact header and should use received SDP.
Every domain's proxy is responsible to fix its client's signaling.

If these rtpproxy use the same IP as the
Kamailio's SIP signalling IP,
then there is no problem and no need to use "-r" flag.
inaki,
does it work in the common case where there is two sip proxys and two
rtpproxies belonging to two organizations that don't have any trust
relationship between them and ip addresses of the rtpproxies are not the
same as sip proxy ip addresses?
