I try to send keepalive requests (options) to clients at usrloc
I tried 4 mechanisms
1) nathelper
modparam("nathelper", "sipping_method", "OPTIONS")
modparam("nathelper", "natping_interval", 15)
modparam("nathelper", "ping_nated_only", 0)
modparam("nathelper", "sipping_bflag", 7)
modparam("nathelper", "sipping_from", "sip:pinger@mydomain")
but it didn't send keepalives to noone client
2)nat_traversal
I tried to trigger keepalives with nat_keepalive() when REGISTER coming to
my service
It works fine with UDP packets
modparam("nat_traversal", "keepalive_interval", 15)
modparam("nat_traversal", "keepalive_method", "OPTIONS")
modparam("nat_traversal", "keepalive_from", "sip:pinger@mydomain")
modparam("nat_traversal", "keepalive_state_file",
"/var/run/keepalive_state")
3)So I also tried to do it with WebSocket keepalive mechanism, but it still
not work for (off course I checked only WS devices)
modparam("websocket", "keepalive_mechanism", 15)
modparam("websocket", "keepalive_timeout", 15)
modparam("websocket", "keepalive_interval", 15)
4) I tried to do it with tcpops
Only for ws and tcp (WS is use TCP as i know)
tcp_keepalive_enable("15", "5", "15");
same result...
So I need mechanism to check all devices for keepalive. I think nathelper
works with all protos (As I read at docs)
Can somebody explain to me what I doing wrong?
