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 -… [View More]

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 … [View More]

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.… [View More]

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 ？

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/… [View More]
