Hi Daniel,

Thanks for reply.

kamailio-1.5.3
mediaproxy-2.3.8 + nathelper

do you need this combination? nathelper is better integrated with rtpproxy. If you look at default kamailio config for 1.5.3 you will see nat traversal logic with nathelper+rtpproxy. You just ahve to run a sed command to enable it. Try with it to see if same issue happens. If not, compare with your config logic and try to addapt.

Cheers,
Daniel
kamailio.cfg

loadmodule "mediaproxy.so"
modparam("mediaproxy", "mediaproxy_socket", "/var/run/mediaproxy/dispatcher.sock")

modparam("mediaproxy", "signaling_ip_avp", "$avp(s:nat_ip)")
modparam("mediaproxy", "media_relay_avp", "$avp(s:media_relay)")

loadmodule "nathelper.so"
modparam("nathelper", "natping_interval", 60)

Hi Friends,

Outbound calling works fine.
When I receive an inbound call, the phone rings, but when I pick up the phone, the conversation does not get established.

I have call from inside NAT extension number to Outside NAT extension ( Outboud call ) then call get established and two-way audio work fine

but when I have call from Outside NAT extension to Inside NAT extension (Inbound call ) then phone rings,

but when pickup the phone, audio is not present.

During inboud call RTP packets are not transmit whereas Outboud call RTP packets transmit successful.

Sometimes, Inbound and Outbound call only one-way audio present.

Can anybody help me, or point me to a previous thread where this issue was discussed and solved?

what are you using for nat traversal? nathelper + rtpproxy? What is the kamailio version you run?

Cheers,
Daniel
