Hello,
have you enabled the nat traversal in kamailio's config file? From the
respective tutorial, the config file should contain:
#!KAMAILIO
#!define WITH_MYSQL
#!define WITH_AUTH
#!define WITH_USRLOCDB
#!define WITH_NAT
#!define WITH_TLS
plus update to rtpproxy module parameter:
modparam("rtpproxy", "rtpproxy_sock", "unix:/var/run/rtpproxy/rtpproxy.sock")
If you did all above, can you use tcp instead of tls for sip and send
the output of ngrep taken on kamailio server for a call that does not work:
ngrep -d any -qt -W byline port 5060
Cheers,
Daniel
