[Kamailio-Users] no inbound sound even with RTPproxy

Hello I have Kamailio with Nathelper and RTPproxy running this way: rtpproxy -l xxx.xxx.xxx.xxx -u mysql -s udp:localhost:7722 I think RTPproxy is working fine with NAThelper, because Kamailio logs say: "RTPproxy found - support enabled" X-Lite and SNOM phones behind NAT work fine. But when I try to connect with an Asterisk behind NAT, the sound doesnt pass through the Asterisk client (the Asterisk client doesn't receive sound). I already tried in 2 different NATs, with no firewalls. Kamailio logs show no errors. This is my Asterisk config: [kamailio] type=peer host=xxx.xxx.xxx.xxx disallow=all allow=ulaw allow=alaw allow=gsm allow=g726 qualify=1000 username=my_username fromuser=my_username secret=password sip*CLI> sip show peers Name/username Host Dyn Nat ACL Port Status kamailio/my_username xxx.xxx.xxx.xxx 5060 OK (890 ms) Im not sure if the problem is in Kamailio or Asterisk config. How can I be sure? How can I debug the RTP stream in Kamailio and RTPproxy?
