Remove a Line from SDP
by egemen ulus 18 Jun '20

18 Jun '20

Hi all, I am trying to remove a line from the SDP body of INVITE on kamailio 4.4 via SDPOPS module but it does not work even though there is no any error message. This is how I configure kamailio.cfg, it matches with if condition and executes "sdp_remove_line_by_prefix" function, but when I check sended INVITE, I still see the line that beginning with "a=rtpmap". I thought, in the RELAY function, the sdp body might not prepared yet? Is there any suggestion to remove a line from the SDP body? route[RELAY] { ... ... if(is_method("INVITE")) { if( $ct =~ "0553847<tel:+10553847>aaaa"){ xlog("L_WARN", "$ct check_this \n"); sdp_remove_line_by_prefix("a=rtpmap"); } } } /path/kamailio[10332]: exec: *** cfgtrace:request_route=[RELAY] c=[/path/kamailio.cfg] l=614 a=16 n=if /path/kamailio[10332]: exec: *** cfgtrace:request_route=[RELAY] c=[/path/kamailio.cfg] l=611 a=26 n=xlog /path/kamailio[10332]: WARNING: <script>: <sip:0553847<tel:+10553847>aaaa@x.x.x.x:5060> check_this /path/kamailio[10332]: exec: *** cfgtrace:request_route=[RELAY] c=[/path/kamailio.cfg] l=612 a=25 n=sdp_remove_line_by_prefix /path/kamailio[10332]: exec: *** cfgtrace:request_route=[RELAY] c=[/path/kamailio.cfg] l=622 a=16 n=if Regards Egemen U.

Dispatcher module and hash algorithm
by Luis Rojas G. 13 Jun '20

13 Jun '20

Hello, I noticed a couple of strange behaviors, using this version : kamailio-5.3.3-4.1.x86_64 I am using algorithm "0". Hash over Call-ID. The reason for that is that I am just re-sending the message, using send_udp(), to a destination in a group from file dispatcher.list. Kamailio is completely stateless, it does not need to remember anything. And using a hash over Call-ID I can be sure that any other message related to the same call will be sent to the same destination : retransmissions of the INVITE, CANCEL, ACK, BYE, etc. I general, it works, but I detected two problems. I have a group of 5 destinations, where every server is running at 80% of the nominal load. It's a 4 + 1 configuration, for redundancy. I know it's not 100% evenly distributed using hash over Call-ID, but in practice it's almost perfectly even. However, if one node is down, instead of having the four alive running at 100%, I get three running still at 80% capacity, and one is sent 160% of the load (which of course can't process). it seems, all traffic that was supposed to be sent to the failed node is transferred to the same unique destination. That implementation makes my solution for redundancy worthless. Why didn't the implementation use, for instance, a re-hash over the hash? That would allow to redistribute "evenly" over the remaining servers. I tried to solve this by repeating the entries in dispatcher.list, as I noticed that kamailio doesn't check if different lines contain duplicated uris. For instance, if I have two lines with "destination A", and one line with "destination B", like this: 0 sip:server_A 0 sip:server_A 0 sip:server_B I see that "destination A" receives twice the amount of SIP OPTIONS that "destination B" receives. And so, I used this dispatcher.list : 0 sip:server_1 0 sip:server_2 0 sip:server_3 0 sip:server_4 0 sip:server_5 0 sip:server_1 0 sip:server_3 0 sip:server_5 0 sip:server_2 0 sip:server_4 0 sip:server_1 0 sip:server_4 0 sip:server_2 0 sip:server_5 0 sip:server_3 0 sip:server_1 0 sip:server_5 0 sip:server_4 0 sip:server_3 0 sip:server_2 (it's not a random order. It follows a sequence) I thought : "what a genius I am. This way, if any node fails, and kamailio select the "next" to send the traffic to, it will distribute evenly over the rest". It doesn't work. I detected something that looks like a bug. If one entry is repeated at least once, for instance : 0 sip:server_1 0 sip:server_1 0 sip:server_2 0 sip:server_3 0 sip:server_4 0 sip:server_5 if server_1 is down, kamailio still sends some of the INVITEs to it. Not all of them, but many. I can see the SIP OPTIONS been sent to it, and the response "ICMP Destination Unreachable", so Kamailio knows that server_down. However, still sends INVITE requests to that failed node. Look at this trace : You can see all the failed SIP OPTIONS. Still, kamailio sends traffic to that server. It does not send traffic to a failed destination if it's listed only once in dispatcher.list Any ideas?

RPC Command tm.clean

Unfortunately, I don’t understand what this command is for, because in my view, expired transactions are automatically deleted. This is all I could find: pc command tm.clean to clean long time expired transactions (for troubleshooting purposes) [1] <https://www.kamailio.org/wiki/features/new-in-5.1.x> So, can you give an example when a transaction can remain in memory? Thanks!

I am trying to setup kamailio in such a way that kamailio acts as a load balancer for 2 or more asterisk systems. i have following queries. 1. As i understand , all the SIP registration will be done with Kamailio and the Media of the calls will be routed to Asterisks in a round robin fashion. In such a case , is it required that all the extension numbers to be used are to be configured in all the asterisk systems included in the setup ? 2. If extension 1000 is in asterisk1 and extension 1001 is in asterisk2 , then is it possible to make internal calls between these extensions ? 3. Is it possible to have TLS based registrations to Kamailio 4. My plan is to build a system which can handle 10000s of extensions . So the system is supposed to be scaled up by adding more asterisk servers in order to accommodate more and more extensions as required . THanks and Regards Abdul Rasheed

Prometheus module stat
by David Villasmil 12 Jun '20

12 Jun '20

Hello all, Anyone here uses the prometheus module? There’s a core stat that includes a hyphen (“-“) and Prometheus doesn’t support that, only underscores are allowed kamailio_usrloc_location-contacts I’m thinking maybe I can create a custom counter and set it to that stat but with the correct name, is that possible? -- Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

facing Call Connection and Disconnection issue in Kamailio SIP Server
by Rajkumar Samikkannu 12 Jun '20

12 Jun '20

Hi There, This is Raj. We have successfully installed Kamailio SIP Server by following this documentation link https://kamailio.org/docs/tutorials/5.3.x/kamailio-install-guide-git/#insta… We created some users and those users are in the Subscription Table. We registered(logged in) some users on our client side. We could get Acknowledgement while we registered(logged in). We couldn't get any acknowledgement while we tried to make a call or send a message. We got a "Request Timeout" Error in Client Side. If anyone knows about this issue, please guide us what we should do. Thanks in advance.

Which mode to capture "written to network" traffic with homer and topos
by Karsten Horsmann 12 Jun '20

12 Jun '20

Hi Mailinglist, some of my kamailio-version is 5.3.4 with topos. During the last discussion about sip_trace_mode("t") i found new behaivor. With this tracingmode i see the "internal" before topos writing. Here my questions: Can i change it to "whats on the wire" (topos rewritten mode)? I didnt checked all modes. And if so, can i switch that on-the-fly with $var for example? For topos debugging its fine with sip_trace_mode("t") - not for "hey carrier, you made some mistakes". #!ifdef WITH_HOMER #Siptrace modparam("siptrace", "force_send_sock", "MY_LOCAL_SENDSOCK") # local interface from where to send the duplicated traffic modparam("siptrace", "duplicate_uri", "MY_HOMER_CAPTURE") modparam("siptrace", "hep_mode_on", 1) # enable/disable Homer encapsulate mode modparam("siptrace", "hep_version", 3) # HEPv3 the timestamp and capture agent ID will be included in the HEP header modparam("siptrace", "trace_to_database", 0) # trace to database modparam("siptrace", "trace_on", 1) # enable/disable trace modparam("siptrace", "trace_mode", 0) # default 0, if 1 then you dont need call siptrace flag or sip_trace() modparam("siptrace", "hep_capture_id", 8) # capture agent id Limitation: 32-bit for HEPv3. #!endif #!ifdef WITH_HOMER # Set the tracing mode: message, transaction or dialog.

Does DMQ auto-discover cluster members + how?
by George Diamantopoulos 09 Jun '20

09 Jun '20

Hello all (again), When running dmq.list_nodes on one of my production kamailio servers, I get several entries corresponding to staging instances of kamailio. These staging instances are located on separate broadcast domains (different VLANs), and none of them are configured in the notification_address parameter for the dmq module. How do they end up there, and how do I get rid of them? Thanks! George

RTPProxy Traversal for all Calls

All, Hopefully a quick answer on this one. I am looking for away to have all traffic traverse the RTP relay, not only NAT. Thinking there should be an easy way to do this with RTPPROXY but haven't been able to figure it out. Using Kamailio 5.3 with RTPProxy 2.2 Thanks, Mike
