Please always send the emails to the mailinglist.
Typically, RTP goes directly between the user agent, not via the proxy.
Only in certain situations the rtpproxy is necessary (user is behind
symmetric NAT)
In must situations, the NAT problem can be solved by using STUN and
rtpproxy is not necessary. Nevertheless a rtpproxy is necessary in
certain situations and therefore (as traffic matters) it makes sense to
use multiple rtpproxys.
