Hello, Arjun!

Are you sure rtpproxy is running and listening on that port? Have you checked rtpproxy log for errors?

Hi All,

Greeting to All!!

I have opensips and rtp proxy in the same machine with a public IP. When I start the opensips with rtp proxy I get the below error.

/usr/local/sbin/opensips[1691]: WARNING:nathelper:rtpp_test: can't get version of the RTP proxy /usr/local/sbin/opensips[1691]: WARNING:nathelper:rtpp_test: support for RTP proxy <udp:127.0.0.1:7890> has been disabled temporarily /usr/local/sbin/opensips[1683]: ERROR:nathelper:send_rtpp_command: can't send command to a RTP proxy /usr/local/sbin/opensips[1683]: ERROR:nathelper:send_rtpp_command: proxy <udp:127.0.0.1:7890> does not respond, disable it

I started the rtp proxy with the below command,

./rtpproxy -l my_public_ip -s udp:127.0.0.1:7890 -F

My opensip.cfg file has the following additions for NAT Traversal,

#------Nat Params-------------
modparam("usrloc","nat_bflag", 6)
modparam("nathelper","rtpproxy_sock", "udp:127.0.0.1:7890")
modparam("nathelper","natping_interval", 30)
modparam("nathelper","ping_nated_only", 0)
modparam("nathelper","sipping_bflag", 7)
modparam("nathelper","sipping_from", "sip:pinger@PROXY_IP")
modparam("registrar","received_avp", "$avp(i:42)")
modparam("nathelper","received_avp", "$avp(i:42)")

Please let me know where is the mistake. Any help is deeply appreciated.

Thanks,
Arjun
