Re: [SR-Users] nat_uac_test not recognized command in onreply_route

Yup.  The default configuaration already have the nathelper.so loaded.  Plus, there are other places in the config where nat_uac_test was called but never error out.

So I'm following the instructions in the Kamailio 5.1.x wiki module page for websocket configuration and it specifically mention to set this block: onreply_route[WS_REPLY] {         xlog("L_INFO", "[CSeq $cs] Is in WS_REPLY.");         xlog("L_INFO", "[CSeq $cs] Sending $rs $rr to $sel(via[2].host) via $sel(via[2].transport) len: $ml");         xlog("L_INFO", "[CSeq $cs] \n$mb \n");         if(nat_uac_test("64")) {                 # Do NAT traversal stuff for replies to a WebSocket connection                 # - even if it is not behind a NAT!                 # This won't be needed in the future if Kamailio and the                 # WebSocket client support Outbound and Path.                 add_contact_alias();         } } When I did this and started up Kamailio, it gave me an error: Jan  3 22:19:43 sjomainkama55 kamailio: ERROR: <core> [core/cfg.y:3309]: yyparse(): cfg. parser: failed to find command nat_uac_test (params 1) I moved that if statement to a route block and I was able to start it up. The wiki page for nathelper module specify this function can be run in onreply_route as well: 5.5.  nat_uac_test(flags) Tries to guess if client's request originated behind a nat. The parameter determines what heuristics is used. Meaning of the flags is as follows: * 1 - The “Contact” header field is searched for occurrence of RFC1918 or RFC6598 addresses. * 2 - the "received" test is used: address in the “Via” header is compared against source IP address of signaling * 4 - The Top Most “Via” is searched for occurrence of RFC1918 or RFC6598 addresses * 8 - The SDP is searched for occurrence of RFC1918 or RFC6598 addresses * 16 - Test if the source port is different from the port in the “Via” header * 32 - Test if the source IP address of signaling is a RFC1918 or RFC6598 address * 64 - Test if the source connection of signaling is a WebSocket * 128 - Test if the “Contact” header URI port differs from the source port of the request (Warning: this is might be legal or even intended combination in non NATted scenarios) All flags can be bitwise combined, the test returns true if any of the tests identified a NAT. This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE. is this some known bug in 5.1.x?
