Hi, sir,
We try to setup Mediaproxy on CentOS 6.6 with kamailio-4.2.1 SIP server. We
use Linphone android version as SIP client to test.
attached kamailio.cfg.txt is our kamailio-4.2.1 SIP server config file. pls
help to rename kamailio.cfg.txt to kamailio.cfg.
kamailio-4.2.1 SIP server is run on public IP server,and  Linphone SIP
client is run behind NAT.
The problem is that only callee can hear caller's rtp audio data. caller
can not hear callee's audio data. And the call will auto disconnect after
about 30s time out.
Below's our modification regarding the kamailio.cfg file,pls help to check
if this is OK or not ?
#foxconn gallice add start
#### MediaProxy module
loadmodule "mediaproxy.so"
modparam("mediaproxy", "disable", 0)
modparam("mediaproxy", "ice_candidate", "high-priority")
modparam("mediaproxy", "mediaproxy_socket",
"/var/run/mediaproxy/dispatcher.sock")
modparam("mediaproxy", "mediaproxy_timeout", 500)
modparam("mediaproxy", "signaling_ip_avp", "$avp(nat_ip)")
modparam("mediaproxy", "media_relay_avp", "$avp(media_relay)")
#foxconn gallice add end
# account only INVITEs
 if (is_method("INVITE")) {
  setflag(FLT_ACC); # do accounting
  use_media_proxy(); #foxconn gallice add
 }
# Manage incoming replies
onreply_route[MANAGE_REPLY] {
 xdbg("incoming reply\n");
 if(status=~"[12][0-9][0-9]")
        {  #foxconn gallice add
  #route(NATMANAGE); #foxconn gallice delete
                use_media_proxy(); #foxconn gallice add
        }  #foxconn gallice add
}
For mediaproxy,we can see the media related processes are already run.

31218 ?        SL     0:16 python ./media-relay start
