No, if you are using latest rtpproxy from cvs and nathelper from
unstable.

Please send me the output of:
head -1 sip_router/modules/nathelper/nathelper.c
and
grep Id:  rtpproxy/main.c

It might also be a false alarm, e.g. you start first ser and then
rtpproxy => you'll get some rtpproxy not found errors on startup, but 
 once rtpproxy is started + 1 minute it should start to work.

If it still does not work, send me also the output of:
netstat -axep |grep rtpproxy

The unstable nathelper & rtpproxy can use UDP instead of unix sockets
for communicating between them. This means you can have ser+nathelper on
one machine and rtpproxy on another one.
