[OpenSER-Users] Issue calling use_media_proxy() at on_reply_route.

by Sergio Gutierrez

Hello all. We are facing some problems in our deployment of OpenSER, related to NAT Traversal solution using MediaProxy. In our scenario, using the the sample configuration NAT detection works right for REGISTER method, and for INVITE's sent from clients behind NAT, but, incoming calls originated from transparent clients, directed to clients behind NAT do not work, and do not pass through MediaProxy. Services based on re-INVITES do not work either. To solve that issue, we tried to intercept the 200 OK answer coming from NAT client, so that we could call use_media_proxy(), but, we get the error: "Empty Response from media_proxy()" Our configuration is more or less like this: # In the beginning of the main route if(client_nat_test("7")) { setflag(2); fix_contact(); }; ..... if(is_method("INVITE")) { if(isflagset(2)) { use_media_proxy(); }; t_on_reply("1"); } .... on_reply_route[1] { if (status =~ "(18[0-3])|(2[0-9][0-9])|(1[0-9][0-9])") { if (client_nat_test("3")) { fix_contact(); use_media_proxy(); } } } That is a very brief configuration fragment, but it is more or less the schema of configuration we are using. So far, our solution to be able to have the whole services working is marking all the calls so that they pass through the mediaproxy, but we are not sure if that is a good solution. Thanks in advance for every hint or suggestion.

[OpenSER-Users] RE: NAT question

by Papadopoulos Georgios

Hi Inaki, Why would you leave out the "4" flag test in nat_uac_test() for the replies? Of course if I leave out the "2" test then my example works (I have tested it) but I am afraid that this will break some other NATed senario. And if leave out the "2" test, should I also leave out the "16" test?

RE: [OpenSER-Users] NAT question

by Papadopoulos Georgios

Hi Bogdan, I understand that 200 OK should not be fixed by proxyA. Maybe what I don't understand is what nat_uac_test("2") does and when to use it. Following is an example where clientA = demo1(a)altecnet.gr clientB = sip_test_1(a)i-call.gr proxyA = 213.5.43.4 proxyB = 213.5.43.134 When proxyA goes in the onreply_route for the 200 OK, nat_uac_test("23") returns true (I guess because of the "2" flag) and proxyA fixes the contact again which is wrong. So, would it be safe to use nat_uac_test("23") for the requests and nat_uac_test("21") for the replies? I am afraid this would break the simple case with 2 NATed clients and only one proxy: clientA ------> proxyA ------> clientC thank you for your help George # U 2007/08/08 10:11:34.233164 213.5.43.134:5060 -> 213.5.43.4:5060 SIP/2.0 200 Ok.
