HI,
I need a little help with nat. UAC register's ok and it is reachable but
after a while it become unreachable due to nat issue. If I use
nat_keepalive on uac deivce everything is ok, but I would like that this
is handled by opensips.
I tried to use nat_keepalive but getting all the time this:
54.820695 opensips -> uac_public_ip SIP 308 Request: NOTIFY
sip:uac_public_ip:13401 |
54.829847 uac_public_ip -> opensips SIP 297 Status: *481 Call
Leg/Transaction Does Not Exis*t |
What is the best way to implement this?
modparam("registrar", "received_avp", "$avp(received_avp)")
modparam("registrar", "tcp_persistent_flag", 10)
modparam("nathelper", "received_avp", "$avp(received_avp)")
modparam("nathelper", "natping_interval", 10)
modparam("nathelper", "ping_nated_only", 1)
if (nat_uac_test("18")) {
xlog("fixing nat");
if (method=="REGISTER") {
nat_keepalive();
fix_nated_register();
} else {
fix_nated_contact();
}
force_rport();
}
tnx!
miha
