Yes, I agree on it. However I just wanted to mean that using a
media-proxy is not the best solution for all the cases, specially when
clients are behind same NAT (an office for example) and the PBX/Proxy
is hosted in some datacenter.
Also, for calls to a gateway in our same datacenter, forcing the RTP
through a media-proxy is not the only solution. Using SessionTimers
(so a B2BUA is required and not just a proxy) is also a good solution
(and cheaper since no servers are needed for relaying the media).

Just my opinion. Regards.
