nat_uac_test not recognized command in onreply_route

by Andrew Chen

Hey it's me again. 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?

Unable to start Kamailio with acc_json

Dispatcher probing

by Duarte Rocha

Hey. I have another question regarding the Dispatcher Probing. In my SBC, a Gateway is defined by it's IP, Port and SAP (Kamailio's IP used for signaling). Those 3 parameters are defined in the Gateway table. In this case ( using Options for probing), i only have access to the destination IP ($dd) and Port ($dp). I need to know the SAP associated to the gateway that is currently being probed, in order to force the correct socket in the OPTIONS request. Is there any way to get more info about the db line that is being read by dispatcher for the probing? If that's not possible i was thinking about querying my db for the Ip:Port pair and if i got more than one result, do forking using the the SAPs in the results, sending multiple OPTIONS through the multiple sockets. In this case, if only one of the OPTIONS is answered, will the gateway still appear as "Active" ? Best Regards, Duarte Rocha

Kami, rtpproxy, T38 fax - anyone?

by yu＠yu-boot.ru

Yet again, fighting against strange fax behavior on Kamailio. When call is routed from device behind Kami and uplink is plain old Mediant2000 gateway to E1, T.38 always correctly established via reinvite and fax works perfectly. When call is routed to anything else including local Asterisk or Freeswitch, seems called don't hear fax noises and quickly throw BYE to me. Asterisk just don't see anything about UDPTL. Even more confusing, "near" device drops a call when detects fax tones from Asterisk or Yate. What can it be? SDP seem to be all transformed as they should be, I cant see anything wrong or different on SIP dumps. Rtpproxy is on bridge mode. Local device is Audiocodes MP118 and on private addressing, another end of Kami is on static IP. Voice calls work perfectly on this configuration. I can provide anything configs dumps etc, if it will help to solve this issue. Anyone using rtpproxy bridge and working T.38? Help me please. -- sent from myMail for Android

Sipt redirection number

by Duarte Rocha

Greetings, Regarding the module sipt and $sipt(redirection_number). Does this PV can show non digits correctly? I have a redirection number that has one char in the middle, like this "12C34567899". However, when i print the PV, i get "12<34567899". How can i fix this? Thanks, Best Regards, Duarte Rocha

Best place to change mem settings

by Duarte Rocha

Greetings, As far as i can tell, i have 3 ways to permanently change the memory settings in Kamailio : /etc/init.d/kamailio , /etc/default/kamailio and src/core/config.h. What's the priority between them? If i have different values in all 3 of them, which one will be used? Which is one is the best to use reliably? I recently upgraded my Kamailio from 5.0 to 5.2 and i need 12Mb of PKG. Before starting the new version for the first time i changed the values in /etc/default and the memory error didn't go away. It only worked after i changed it in core/config.h and recompilled. After that, i started Kamailio and i could do the changes in /etc/default without any problem. Does this happen for a reason? Best Regards, Duarte Rocha

rtpengine in stateless kamailio

by Yuriy Gorlichenko

Hi! Happy new year to all!!! Look like I am first in this year wit hthe questions in this list :-). I'm using stateless kamailio and RTPengnine to build some kind of the stateless cluster I found that kamailio keeps some data in the SHMEM in case of using RTPengine module even if it is not a rtpengine_manage function but offer/answer/delete In this case if INVITE (offer) handled by 1-st kamailio in my cluster, and BYE/CANCEL handled by second kamailio in the cluster - 1-st kamailio (which has been used for offer) will hase kinda internal "memory leak" (in SHMEM it never decrased) At the rtpengine module source I found some transation dependencies for the rtpengine_manage function but did not find for the offer/answer/delete I supposed these 3 functions just sending requests to the rtpnegine with keys and not storing anything So my question - is it possible to use RTPengine module in stateless way to avoid internal "memory leak" because in my scenario I have big chance never receive BYE/CANCEL on the machine that started handle particular call
