[SR-Users] Kamailio LB: how to get Asterisk to do the RTP

[Tickling Contest]

I added the #!define WITH_NAT option, and now the call can only be made one
way. RTPProxy was started like so:

$ rtpproxy -l 192.168.1.101 -s udp:localhost:7722 -u kamailio

root at kamailioA:~# netstat -pln | egrep "kamailio|rtpproxy"
tcp        0      0 192.168.1.101:5060      0.0.0.0:*               LISTEN
     10112/kamailio
tcp        0      0 127.0.0.1:5060          0.0.0.0:*               LISTEN
     10112/kamailio
udp        0      0 192.168.1.101:5060      0.0.0.0:*
    10081/kamailio
udp        0      0 127.0.0.1:5060          0.0.0.0:*
    10081/kamailio
udp        0      0 127.0.0.1:7722          0.0.0.0:*
    10042/rtpproxy
raw        0      0 0.0.0.0:255             0.0.0.0:*               7
    10081/kamailio
unix  2      [ ACC ]     STREAM     LISTENING     33357    10102/kamailio
   /var/run/kamailio//kamailio_ctl

My full config is at

BTW, my entire setup, kamailio, asterisk and the phones etc. are in one
private network. I think setting realtime endpoint with "direct_media=no"
is pointless as all of these interactions are fronted by Kamailio.

What's going on here?  Any help is appreciated.
