asterisk users - Jun 2006 - using mediaproxy for both ASTERISK and SER

Hello Masters,

                  I am using SER as proxy and registrar and redirect server
and iam using MEDIAPROXY for SER to handle Nated calls ,

So, now i want to connect Asterisk to SER to handle only pstn calls so how
the process here goes on ... I mean is, when a sip user who registerd at SER
calls to pstn then SER will forward it and Asterisk will try to connect the
pstn number and asterisk rtp proxy will handle one leg and on other leg SER
mediaproxy will do it

instead of both can we use only one Mediaproxy to do that ? is there any
chance to do that ????!

(in the sense that  Asterisk is a registered user agent for SER)



UA<---->|SER|<------>|ASTERISK|---->PSTN
               |                     |
               |                     |
             -----                 -----
         Media                RTP
        Proxy                    proxy



so here when call from pstn, the asterisk will send sip request to SER and
SER looks in location database and sends an invite messsage to sip client

where i getting confusion is there are two mediaproxies to handle this call

1) whether mediaproxy will handle?
2) rtp proxy will handle?

please clear my doubt ...


           Thank you
Regards
Ravi
