A bit trick in msg_translator.c source file
by Mojtaba 29 Dec '18

29 Dec '18

Hello , Does anybody know why the lenght of both ip-address (s and name) in check_via_address function in msg_translator.c source file dose not check first? Actually i think it's better do. For example if via:192.168.122.1 and src:192.168.122.100, the result returned true, as they are not the same! With.Regards. Mojtaba Happy new year --Mojtaba Esfandiari.S

Re: [SR-Users] kamailio does not responde if an rtpengine is unreachable
by David Escartin 29 Dec '18

29 Dec '18

hello Daniel Thanks a lot for the update. We will also test it. It has not 100% relation with this issue, but i only wanted to share the setup we have for cases where a rtpengine fails having high traffic load, to minimize the impact on the kamailio processes. modparam("rtpengine", "queried_nodes_limit", 2) modparam("rtpengine", "rtpengine_retr", 2) modparam("rtpengine", "rtpengine_tout_ms", 350) considering we don't use sets with more than 2 rtpengine instances, at least for retry attempts. And your rtpengine instances are in the same network too. this works quite fine for us, there are some few secs of impact while the rtpengine is marked as disabled, but the system recovers quite ok. best regards david -----Original Message----- From: "Daniel-Constantin Mierla" <miconda(a)gmail.com> Sent: Friday, December 28, 2018 9:15am To: "Juha Heinanen" <jh(a)tutpro.com> Cc: "Kamailio (SER) - Users Mailing List" <sr-users(a)lists.kamailio.org> Subject: Re: [SR-Users] kamailio does not responde if an rtpengine is unreachable I just pushed a series of commits trying to rework how loading (and reloading) of rtpegines list is done, to avoid that sync'ed probing, which can take long if any of the rtpengines is down. Now, building the local (per process) structures/sockets for rtpengines during kamailio start up is done without locking. This is guarded by the fact a reload command can be executed only after all children were initialized (added also with these commits). Moreover, the probing of rtpeningesis done only by child process 1, because the status is stored in shared memory list, so it is visible in all children. Based on my understanding there, doing probing from all processes is useless now, that was probably kept from the time when the list was not stored in shared memory, from the early rtpproxy times. There is also a restriction on how often the rtpengine list can be reloaded, now having a 10 seconds interval guard. I added this because the reload is done over the old list, not building a new list to swap with the old one. So it requires some time to walk through the existing list and update based on the new records. I went this way for now, even building a new list may be better/safer in long term, but it would require more work. I also wanted to avoid being very intrusive right now, given that those patches would need to be backported. The last relevant change was to use a version number to discover when a reload was done. So far, as I understood, it was relying on the number of rtpengines, but one may trigger a reload with same rtpengines, but different attributes (e.g., disabled or not). Having a version number is better in detecting when each worker needs to rebuild its local list of sockets, as well as for troubleshooting, because a value is increased with each reload, so easier to track if it was done or now. I didn't have time for any tests, so it would be good if you can test and report if works as expected. All related commits are in master, if they prove to work fine, we can backport all those patches.

kamailio does not responde if an rtpengine is unreachable
by Juha Heinanen 28 Dec '18

28 Dec '18

I noticed that if one rtpengine in a set is unreachable, kamailio 5.2 does start, but does not process any SIP requests. Is this intentional? -- Juha

Re: [SR-Users] Kamailio 5.2 0IMS configuration documentation
by Woscek, Martin W. 27 Dec '18

27 Dec '18

Hi Yasin, That VM was built with 4.3.4. It did help in fixing the scripts to build the pcsf, scscf and icscf databases. The config files are different and being that I need to understand the configuration and getting it up and running, isn’t helping much more. Being I need an IMS for lab testing, perhaps 4.3.4 does what I need, then maybe 5.2.0 is not required.

Dispatcher Probing
by Duarte Rocha 27 Dec '18

27 Dec '18

Greetings, I have Kamailio with the Dispatcher module and it's probing mechanics set up. I want to be able to access the OPTIONS request generated by Kamailio in the request_route or somewhere else in the configuration file in order to modify it. Is that possible? Best Regards, Duarte Rocha

xlog $mb produces ERROR
by Andrew Chen 27 Dec '18

27 Dec '18

Hey community, I'm currently trying to config our new 5.1.2 kamailio server and I want to xlog $mb. Whenever I do this, I get an ERROR logged to my syslog Dec 26 21:15:58 sjomainkama55 /usr/sbin/kamailio[5954]: {1 1 INVITE <padding>@<padding>} ERROR: <script>: INVITE sip:<padding>@ sjomainkama55.a.fuzemeeting.com:443 Does anyone know why this is? Also, I noticed I can't get rid of #012#015 at all. I modified the rsyslogd.conf file as instructed here: "i need to add the next line to /etc/rsyslog.conf "$EscapeControlCharactersOnReceive off" and when I did this, the control characters disappear but all it printed out was the first line of the SIP message. I also try to assign $mb to a $var() and do a {re.replace} on that string and that didn't work either. I ended up having to create a side script to parse the whole /var/log/syslog and do regex replace the #012#015 with real newline which is not what I really want for me or anyone else who needs to analyze the Kamailio logs.

Re: [SR-Users] [EXT] Re: Using a network STUN Server

Thank you, I just was not sure what else would cause the relayed packets to not be sent out to my fios router. As mentioned, I can pick any other server in my network and I can see, in the pcap file, that the relay is attempted to the selected server. I verified our ACL and it is it open for TCP output to any IP and Port so that is not the issue. -----Original Message----- From: sr-users <sr-users-bounces(a)lists.kamailio.org> On Behalf Of Alex Balashov Sent: Wednesday, December 26, 2018 12:55 PM To: Kamailio (SER) - Users Mailing List <sr-users(a)lists.kamailio.org> Subject: [EXT] Re: [SR-Users] Using a network STUN Server As STUN is a client-side construct, I am not aware of any functionality Kamailio might have to make *use* of a STUN server for its own representations about its reachability.

Hello All, Can I point Kamilio to use a STUN server located on my network? Kamilio will not relay to my fios router but will relay to other Servers on my network. Thank you,
