Kamailio not listening to proper ipv6 address
by selak Dev 23 Apr '18

23 Apr '18

Hi, I need to enable Kamailio to work with ipv6 also, and I enabled auto_bind_ipv6=1 and when restarted I can see that it is listening to ipv6 ip addresses also. The problem is that it stripped the ip address at the end and it is listening to the wrong one. When I try to register I get timeout, since it is not listening the correct address. ip address of the server is 2604:a880:400:d0::yyyy:xxxx and when I execute "sudo netstat -plnt" too see which app is listening to which address/port I can see: .... tcp6 0 0 2604:a880:400:d0:::5085 :::* LISTEN 17748/kamailio tcp6 0 0 2604:a880:400:d0:::5061 :::* LISTEN 17748/kamailio It somehow stripped the last part of the address (yyyy:xxxx). I dont know if it is related to :: which would be all zeros, but it doesn't work even if i explicitly specify which address to listen with listen=[2604:a880:400:d0:0000:0000:yyyy:xxxx] or listen=tcp:[2604:a880:400:d0:0000:0000:yyyy:xxxx]:5061 or listen=tcp:[2604:a880:400:d0::yyyy:xxxx]:5061 I tried all combinations and the results are always the same... Have anybody had this problem before? Do you know how to fix this? Best regards, Marko Selakovic

select outgoing interface
by Laurent Schweizer 23 Apr '18

23 Apr '18

Dear all, I have a config with multiple interface( multiple IP in same subnet) and want to know how I can select the interface used to send a request (UDP). The best is the possibility to choose for each request the outgoing interface but if it's not possible I think I can also work with a solution where the outgoing interface is defined globally ? I need this because one provider request one IP for inbound call and one IP for outbound call . Thanks Laurent

Variables in database
by Nelson Migliaro 22 Apr '18

22 Apr '18

Hello, I am palnning to set variables to limit the number of channels but I would like to set up them in database in order to upload them without needing to restart the service. I also would like to have that db information to be loaded in memory. So far I only thought in dialplan module but i am looking for a more "fancy" way. Can someone recommend me a module? thank you

Kamailio relays ACK itself
by Volkan Oransoy 22 Apr '18

22 Apr '18

Hi all, I have a Kamailio box which I use as a uac_client. We register a bunch of accounts to remote providers. The box relays incoming calls to a FreeSwitch box. We encountered a strange problem on one account. Kamailio relays the call to my FreeSwitch box successfully but routes the ACK itself which is the reply of 200Ok. I believe this is a provider related issue but I need a technical explanation. Does anyone have any idea? Here is the packet capture: https://pastebin.com/PA8StiWY Thanks, -- Volkan Oransoy

TCP core parameters and TLS
by Alex Balashov 22 Apr '18

22 Apr '18

Hi, Is it reasonable to assume that the various tcp_* core parameters (keepalive behaviour, connection limits, buffer sizes, etc.) also regulate the behaviour of TLS connections, since TLS is encapsulated in TCP? -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

CLID blacklist
by Nelson Migliaro 21 Apr '18

21 Apr '18

Hello, I am looking for a module to block number based on CLID. If the module allows REG expresions it would really make my day. I need to block some callers and I would like to use a module and database to avoid restarting kamailio service everytime a new number appears. Thank you Nelson.-

Kamailio doesn't start with db_mongodb and usrloc.
by Konstantin Polyakov 21 Apr '18

21 Apr '18

Hello! Similar issue but with different symptoms. kamailio 4.4.7 (tried to use db_mongodb module from 5.1.2) usrloc is configured to use db_mode=1 and db_insert_null=1. MongoDB 3.6.3 mongo-c-driver was tested 1.9.2 and 1.9.4. location table contains 300 records. The issue was not reproduced since February when we started a new feature. Now it is reproduced constantly, but on some machines.

question on TM transaction matching
by Kelvin Chua 19 Apr '18

19 Apr '18

i am monitoring an issue with 5.1.2 where a cancel is not being propagated after a 183 is received the packet dump doesn't show anything anomalous. some notes: 1. the invite went out through t_relay(), transaction is tracked 2. cancel is handled this way if (is_method("CANCEL")) { xlog("CANCEL received"); if (t_check_trans()) { route(RELAY); } exit; } 3. if the UAC who is sending the call to kamailio is configured to send invite with RURI without a port i.e. 14087654321(a)w.x.y.z instead of 14087654321@w.x.y.z:6050, then this does not happen 4. can be argued that this is not an issue, and that the client should just be configured properly with outbound proxy and ruri without port. but i am just being difficult here and wanted to understand what is going on with the matching algo.

Info: Kamailio Unit Testing Framework using Docker
by Daniel-Constantin Mierla 19 Apr '18

19 Apr '18

Hello, a while ago, I started to put together a unit testing framework for Kamailio. It was more or less inspired from the old shell-based testing framework added by Henning Westerholt many years ago (which still resides in source tree path test/unit/), but now leveraging docker to have an isolated environment for running the tests. The new testing framework is available on github at: * https://github.com/kamailio/kamailio-tests Giacomo Vacca helped a bit so far, he is actually going to present more about it at Kamailio World 2018 (https://www.kamailioworld.com/k06/schedule/). But we want now to get more feedback from community, eventually to adjust the framework to become something easy to use and even more important, to be easy to contribute to. One of the main benefits from my point of view it would be to have the reports of the issues that can be reproduced submitted along with a unit test. It would make it easier to troubleshoot and then after fixing it, would be tested always before releases in order to avoid regressions. Right now, a good help from community would represent converting the old unit tests to the new framework, afterwards we can decommission test/unit. The conversion should be rather easy, as we still rely on shell and the sip tools like sipp/sipsak ... If you want to help here by you need clarifications or get stuck somewhere, just write to mailing list and I would be more than happy to assist. Such contributions should be submitted as pull requests in order to be easy to review: * https://github.com/kamailio/kamailio-tests/pulls Looking forward to your feedback, comments or contributions! Cheers, Daniel -- Daniel-Constantin Mierla www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio World Conference - May 14-16, 2018 - www.kamailioworld.com
