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

Morning What have you got your listen / advertise address / port set as? See this link > https://www.kamailio.org/wiki/cookbooks/5.5.x/core#advertised_address I'd probably start by looking at that.

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

kamailio Behind nat. How Record-Route should be added ？
by 城门虾米 08 Oct '23

UA(192.168.0.11) received 183, find Record-Route(36.140.122.12) then send ACK to 36.140.122.12(Kamialio public ip) not 192.168.0.2(kamailio internal ip), so Kamailio can't receive ACK. this is my config，192.168.0.11 -> Kamailio -> Other SBC(public ip) function ksr_request_route() if KSR.is_INVITE() then KSR.rr.record_route(); KSR.nathelper.fix_nated_contact() end end This question has been bothering me for a long time, help me [cid:d1ec74be-1c33-406e-80d5-68663d1cd21f] [cid:bda00d0d-e6e6-4dc9-9462-141ad42b09b8]
