Using DMQ to sync the TM module.
by Michel Pelletier 11 Oct '23

11 Oct '23

Hi, I have 2 kamailio instances behind a load balancer. The problem I have is that the load balancer can only track TCP connections, but not UDP. So one Kamailio instance might send a request using UDP, while the corresponding UDP reply arrives on the other. This doesn't play well with the (stateful) TM module. Is there a way to synchronize the TM module accross Kamailio instances using DMQ? Cheers, Michel Pelletier

rtpproxy -- timeout_socket
by James Lipski 11 Oct '23

11 Oct '23

Hello, I'm a bit confused about a piece of the documentation. I'm using rtpproxy 3.0.1 + rtpproxy module on kamailio 5.6.4. On the rtpproxy module, I'm trying to get the "timeout_socket" param working. From the documentation, I have modparam("rtpproxy", "timeout_socket", "xmlrpc:http://192.168.155.64:8888/XMLRPC") modparam("xmlrpc", "route", "XMLRPC_ROUTE") modparam("xmlrpc", "mode", 1) modparam("xmlrpc", "url_match", "^/XMLRPC") /usr/bin/rtpproxy -i -u rtpproxy -n tcp:192.168.155.64:8888 -l 192.168.155.64 -s udp:127.0.0.1:7333 -m 29152 -M 49150 -d DBUG However when purposely trying to timeout RTP, I'm seeing the following in my rtpproxy logs: Oct 10 00:31:22 localhost rtpproxy[3802129]: DBUG:GLOBAL:rtpp_command_split:401: received command "3801518_4 USc9,0,8,18,101 219b2465decc-n7al36xva4lw 192.168.155.168 2266 C60D788E-8E14A9FA;1 w6p2ke9ttk;1 xmlrpc:http://192.168.155.64:8888/XMLHTTP" Oct 10 00:31:22 localhost rtpproxy[3802129]: ERR:219b2465decc-n7al36xva4lw:rtpp_command_ul_handle:603: invalid socket name w6p2ke9ttk;1 I'm just wondering if I'm missing anything, do I need to define "listen=tcp:192.168.155.64:8888" in my configs? I know that rtpengine is recommended/ I would like to experiement with rtpproxy. Do I need a specific version of rtpproxy in order for this to work -- I did try it with 2.1.1 however that didn't work. Thanks.

Error reporting when developing a custom module to link to a third-party library
by bikq＠163.com 11 Oct '23

11 Oct '23

Dear friends, I have a question: When adding a custom module in kamailio, I referenced a third-party library. There was no problem with compilation, but when I ran it, it reported that the third-party library could not be found. What is the reason? The current Makefile is as follows： ``` # WARNING: do not run this directly, it should be run by the main Makefile include ../../Makefile.defs auto_gen= NAME=rocketmq.so THIRDPARTY=/mnt/vdd/kqbi2/3rdparty ROCKETMQ_ROOT_PATH=${THIRDPARTY}/rocketmq CXX?=g++ LD?=g++ LIBS+=-L$(LOCALBASE)/lib -L$(ROCKETMQ_ROOT_PATH)/lib/linux/x64 crocketmq.o -lstdc++ -lrocketmq DEFS+=-I$(LOCALBASE)/include -I${ROCKETMQ_ROOT_PATH}/include CXXFLAGS=$(CFLAGS:-Wno-deprecated option=) CXXFLAGS+=-Wno-write-strings -Wno-deprecated -Wno-unused-function -Wno-sign-compare -Wno-strict-aliasing include ../../Makefile.modules crocketmq.o: crocketmq.cpp crocketmq.h @echo "Compiling $<" $(CXX) -std=c++11 $(CXXFLAGS) $(CFLAGS) $(C_DEFS) $(DEFS) -c $< -o $@ rocketmq.so: crocketmq.o modclean: -@rm -f crocketmq.o crocketmq.d rocketmq_mod.o rocketmq_mod.d clean clean-modules: modclean proper realclean distclean maintainer-clean: modclean ``` There is no problem in compiling, but when running, the third-party librocketmq.so library cannot be found, and various export LD_LIBRARY_LIBRARY also does not work. ``` 0(13229) DEBUG: <core> [core/cfg.y:2053]: yyparse(): loading module rocketmq.so 0(13229) DEBUG: <core> [core/sr_module.c:516]: ksr_locate_module(): found module to load <lib64/kamailio/modules/rocketmq.so> 0(13229) DEBUG: <core> [core/sr_module.c:573]: ksr_load_module(): trying to load <lib64/kamailio/modules/rocketmq.so> 0(13229) ERROR: <core> [core/sr_module.c:591]: ksr_load_module(): could not open module <lib64/kamailio/modules/rocketmq.so>: librocketmq.so: cannot open shared object file: No such file or directory 0(13229) CRITICAL: <core> [core/cfg.y:3900]: yyerror_at(): parse error in config file /mnt/vdd/kqbi2/install/kamailio/etc/kamailio/kamailio.cfg, line 380, column 12-24: failed to load module ```

Serial Forking with differing next hop for each branch?
by Barry Flanagan 10 Oct '23

10 Oct '23

Hi I have a scenario where I need to implement serial forking but each destination has also a next hop proxy. I can do the forking using append_branch, but how can I set the destination URI for each branch? In some cases the R-URI does not change, only the next hop proxy. Example: R-URI Next Hop user1(a)domain.com XXX.XXX.XXX.XXX user1(a)domain.com YYY.YYY.YYY.YYY user2(a)domain.com XXX.XXX.XXX.XXX I was thinking I could use a htable to store the next hop using the R-URI as the key, but as can be seen above there are possibly duplicate R-URIs with only the next hop changing. Thanks. -- -Barry

0.0.0.0 in VIA header
by Ali Taher 10 Oct '23

10 Oct '23

Hello, I'm using Kamailio as SIP proxy to receive INVITE packets, randomize A-number and then relay it to a certain gateway. I noticed that a Via header is added to the INVITE sent by Kamailio to the gateway with 0.0.0.0 as address as shown below: Via: SIP/2.0/UDP 0.0.0.0;branch=z9hG4bK2d97.61de75dd58fa7ca7450cc8b9b01db62f.0 As far as I know, the IP that should be used in the new added VIA header must be Kamailio IP, but it's not the case here, knowing that Kamailio is not behind NAT. Regards, Ali Taher

CANCEL first, then INVITE.
by James Lipski 09 Oct '23

09 Oct '23

Hello, Is there a way to change the transaction order when a failure fork occurs -- to explain, endpoint 1 calls endpoint 2. Call towards endpoint 2 goes unanswered, and so the call forks to voicemail, I see that an INVITE is sent towards my voicemail server first, followed by a CANCEL towards the endpoint; can I send the CANCEL first to the endpoint and then INVITE towards my voicemail server. I'm essentially using the bundled/sample configurations for testing. Thank you.

kamailio Behind nat. How Record-Route should be added ？
by codenot＠msn.com 09 Oct '23

09 Oct '23

UA1(192.168.0.1) --> kamailio (internal:192.168.0.2 public:1.1.1.1) --> UA2(2.2.2.2) if in UA1 INVITE, I write KSR.rr.record_route(). so UA2(2.2.2.2) received sip msg (Record-Route: <sip:1.1.1.1:7080>), so Kamailio can received BYE/ACK from UA2. but，Kamailio can't received BYE/ACK from UA1. if in UA1 INVITE, i write KSR.rr.record_route_advertised_address("192.168.0.2"), then Kamailio can received BYE/ACK from UA1, but not from UA2. what can i do, let Kamailio receive BYE/ACK from both sides ？

[Dialog Module] questions about early_timeout param
by Abdoul Osséni 08 Oct '23

08 Oct '23

Hello all, Can you please clarify part of the following doc for me? -- 6.7. early_timeout (integer) The timeout (in seconds) after which the dialogs in unconfirmed or early state (no final response received) are destroyed. * Default value is “300 (5 minutes)”. * *Example 1.7. Set early_timeout parameter* ... modparam("dialog", "early_timeout", 180) --- In the case where Kamailio acts as an SBC, will kamailio send a SIP BYE message to both devices (UAC and UAC)? Or Can Kamailio send a BYE message to both parties when timer b has expired? If yes, how to do it? Regards Abdoul

uac_req_send + evroute + crash
by Dr. Barabás Péter 06 Oct '23

06 Oct '23

Hi All, I use kamailio In front of Asterisk and kamailio needs to refresh registrations periodically towards Asterisk to ensure the availability of users from Asterisk side. I use uac module and call uac_req_send() for sending REGISTER requests. I set $uac_req(evroute)=1 The event_route[uac:reply] is called fine, but in kamailio logs I see the next lines: CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f114995ada8), called from uac: uac_send.c: uac_send_tm_callback(860), first free uac: uac_send.c: uac_resend_tm_callback(732) - ignoring After some time, kamailio has crashed.

Crypto module AES algorithm details
by Jayesh Nambiar 04 Oct '23

04 Oct '23

*Hello,* I am running kamailio-5.3.4 on one of my setup and I intend to use the crypto module in the same. I wanted to understand the following details when the module is used: I understand it uses the AES algorithm, is that correct? Does it use AES 128, 192 or 256 bit algorithms? Does it use CBC or ECB mode for AES? The 5.3 version does not have an parameter for init-vector, so does kamailio use any init vector internally in this case? When i compared the encrypted text that kamailio produces and the ones available online, they were producing different outputs even when same shared secret was used. Hence asking for more clarification PS: Upgrading kamailio is my very last option as this is one af an old setup which only needs this feature without much changes. Thanks for any valuable response. *-- Jayesh*

Hello, In reference to this issue https://github.com/kamailio/kamailio/issues/3081 I've been advised to set http_reply_parse to "no" which I did (and it is the default value anyways). # grep http_reply_parse /etc/kamailio/kamailio.cfg http_reply_parse=no After setting this, I still get these parsing errors: { "idx": 23, "pid": 102, "level": "ERROR", "module": "core", "file": "core/parser/msg_parser.c", "line": 748, "function": "parse_msg", "logprefix": "", "message": "ERROR: parse_msg: message=<HTTP/1.1 100 Continue\r\n\r\nHTTP/1.1 200 OK\r\ndate: Wed, 26 Jul 2023 16:43:19 GMT\r\ncontent-length: 224\r\ncontent-type: text/plain; charset=utf-8\r\n\r\n{\"result\": {\"ruri\":\"\",\"fU\":\"\",\"tU\":\"\",\"privacy\":\"\",\"identity\":\"\",\"error\":{\"code\":0,\"message\":\"\"},\"mb\":\"\",\"Headers\":null,\"encrypted\":\"\",\"sipsScheme\":\"\",\"attestation\":\"\",\"authUser\":\"\",\"authPassword\":\"\",\"disableStirShaken\":\"\"}}>" } Is there anything that I am missing beyond setting that parameter?

What is the expected behavior for dispatcher's ds_next_dst?
by geoff.goas＠interoptechnologies.com 28 Sep '23

28 Sep '23

Hello, I have some questions about dispatcher's behavior. I noticed that when I first ds_select_dst() a specific dispatcher group ID, ds_next_dst() will cycle through the active destinations in that group. When it reaches the end of the destinations in the group, it does not return "false", instead it starts to return destinations that are not a part of that group, ie. those destinations which are listed prior to the selected group in the dispatcher.list file. Is this the expected behavior? I've observed it on kamailio 5.3 and 5.5 releases. My dispatcher.list: # Group 1 1 sip:127.0.0.1:5071;transport=udp 8 0 # Group 2 2 sip:127.0.0.1:5072;transport=udp 8 0 # Group 3 3 sip:127.0.0.1:7010;transport=udp 8 0 3 sip:127.0.0.1:7011;transport=udp 8 0 3 sip:127.0.0.1:7012;transport=udp 8 0 # Group 4 4 sip:127.0.0.1:5071;transport=udp 8 0 4 sip:127.0.0.1:5072;transport=udp 8 0 I have the following in failure_route (excerpt): $var(dsFoundDestination) = 0; if (t_any_replied()) { xavp_params_implode("_dsdst_", "$var(dsDestinations)"); xlog("L_INFO", "FAILURE ROUTE: Already have replies on this transaction. Selecting next destination from: [$var(dsDestinations)]"); if (ds_next_dst()) { xavp_params_implode("_dsdst_", "$var(dsDestinations)"); xlog("L_INFO", "FAILURE ROUTE: Next destination selected: [$du] from [$var(dsDestinations)]"); $var(dsFoundDestination) = 1; } } else if (ds_select_dst("3", "8")) // Dispatcher Group 3 { xlog("L_INFO", "FAILURE ROUTE: Did not find any replies on this transaction. Selected destination: [$du]"); $var(dsFoundDestination) = 1; } if ($var(dsFoundDestination)) { $var(logString) = "FAILURE ROUTE: Relayed to [" + $du + "]"; if (t_relay()) { xlog("L_INFO", "$var(logString)"); } } Produces the following logs: FAILURE ROUTE: Did not find any replies on this transaction. Selected destination: [sip:127.0.0.1:7012;transport=udp] FAILURE ROUTE: Relayed to [sip:127.0.0.1:7012;transport=udp] FAILURE ROUTE: Already have replies on this transaction.

Is the solution simply to check that the selected destination is part of the desired group and stop processing if it is not? Thanks for your time.

failure_route, change_reply_status, and append_hf: Not Working as Expected
by sadik.oualla.mohamed＠gmail.com 26 Sep '23

26 Sep '23

Hello Kamailio Community, I'm currently working on a project that involves complex SIP routing and handling. I've encountered some difficulties while using change_reply_status, and append_hf functions in failure_route route in Kamailio. Although the documentation does provide guidance, the behaviors I am experiencing aren't aligning with the expected outcomes. Issue 1: failure_route I've set up a failure_route to handle specific SIP response codes (>4xx). However, I've observed that it get trigered and lunched, but I can't use change_reply_status or append_hf, I was using this first in onreply_route. Issue 2: change_reply_status I tried to use the change_reply_status function to modify the status of SIP replies, but it raises an error that this command cannot be executed here. Issue 3: append_hf I've also attempted to use append_hf in my failure_route block to add headers to replies, but the headers are not being added as expected. As a workaround, I've been using send_reply and append_to_reply for adding custom headers, and they seem to be working as expected. However, I found some old messages in kamailio mailing list, I can summerize what I learned like this ``` #Functions and Context - append_hf(): Adds a header to the currently processed SIP message. If you are in a route {...} block, then this adds the header to the request. If you are in an onreply_route, it adds the header to the reply. This function always acts on the message currently under scrutiny. - append_to_reply(): This function is used to add a header to a reply that will be generated by Kamailio at a later time. This function only affects replies generated by Kamailio itself and is not applicable for messages that are simply being forwarded. #Contexts - route {...}: This is typically where the incoming SIP request gets processed. Here, append_hf() will add headers to that request, and append_to_reply() will add headers to any replies that Kamailio might generate for this request. - onreply_route: This is where incoming SIP replies are processed. Here, append_hf() will act on the reply, not the request. ``` I'd like to know if there is a way to handle sip replies in failure_route, because send_reply make a new reply from kamailio, instead I want to keep some important headers from the original reply. I'd appreciate any insights or guidance the community can offer. Best regards,

RTPengine use single port for all calls
by Mahmood Alkhalil 26 Sep '23

26 Sep '23

Hello Kamailio, Is it possible to use RTPengine with a single UDP port for all calls instead of a range of ports? For example, when an invite is received or sent, the offered SDP for RTPengine is to receive RTP packets on a single port that is the same for all other calls, so that on firewalls only one port is to be opened.
