Development is open for future release of v5.6.x series
by Daniel-Constantin Mierla 22 Apr '21

22 Apr '21

Hello, the branch 5.5 was created, therefore the master branch is open for adding new features, to be part of future release series v5.6.x (or whatever version is decided for next series). Any bug fix committed to master that applies to 5.5.x or older stable branches should be backported as usual with "git cherry-pick -x ..." to appropriate branches like 5.5 or 5.4. Expect that v5.5.0 will be released in a few weeks from now. Based on the workflow used during the past years, the next future release v5.6.0 should be out after another 6-10 months of development, plus 1-2 months of testing, so sometime by end of 2021 or in the first part of 2022.

Reminding again about private/direct emails from mailing lists discussions
by Daniel-Constantin Mierla 22 Apr '21

22 Apr '21

A lot of emails are still sent directly to me after a discussion started on public mailing lists (subject with mailing lists prefix, but the sender header is not the mailing list daemon), I would like to remind that, at least in my case, writing emails directly without cc-ing the mailing list is highly not recommended and there is practically 0 chance to get an answer from myself. The rule is also suggested in the mailing lists presentation page: - https://www.kamailio.org/w/mailing-lists/ Unless I asked explicitly for a private email with some specific details, the message will not be noticed in decent time and therefore not replied. I use this email address for many public mailing lists and it is intended only for that usage, I am reacting based on the filters I created, unmatched messages getting the lowest priority. Therefore if you wrote me and expect a response, re-send the message to the appropriate public mailing list. Checking and answering the messages on Kamailio mailing lists are among the top of priorities on my daily activity, so it is high chance you get the response faster when you write there. Note that you can always mask sensitive data (e.g., replace passwords, IP addresses) before sending logs or config file. There are several common sense as well as technical reasons for keeping the discussion on public mailing lists. Here are some along with other suggestions to improve the likeliness of getting an answer: - we are not answering questions on mailing lists to help only one person, but also other people that may have similar issues in the future -- they can find the answers in the archive with a search engine. Also, other people subscribed to the list can learn from conversation or contribute to the discussion, resulting in better outcome - the amount of unexpected messages is very high -- it is practically a zero chance to get to the folder with messages that didn't match any filter (thus your message is not going to be replied) - whenever I find time, the first emails I answer are those coming on mailing lists. There might be many unanswered as well, people are travelling or having other personal or business projects, so sometime is good to send a reminder if a question does not get an answer - starting with negative approach or no technical content, like you are going to use something else if you don't get a reply instantly, or this application not good or is missing what so ever tutorial giving exactly the solution you need, or simply asking for full config of complex requirements, is not helping at all, but actually making people to ignore your messages. Start with what you tried and where you got stuck. Everything you get is for free, have appropriate expectation and behavior.

Branching 5.5 on git repo for 5.5.x releases
by Daniel-Constantin Mierla 21 Apr '21

21 Apr '21

Hello, since freezing the development for 5.5 series, I did quite a lot of code analyzing with a bunch of tools as well as run various tests, no major issue being in my list at this moment, therefore I think we can plan branching 5.5 on git repo in the near future. If there is no other suggestion or argument against it, I propose to create the branch 5.5 on Thursday next week (April 22, 2021). After that, master branch will be open for new features (to become part of 5.6 or what ever version will be decided to be next), testing will continue for branch 5.5 for another 1-2 weeks, then we will release 5.5.0 as first stable version in the 5.5.x series.

Dialog - Profile cleanup before event_route[dialog:end]

Hi guys, I was trying to read the profile of a dialog on the event_route[dialog:end] and noticed that dialog profiles are not available at this point. My cfg code that doesn't work: event_route[dialog:end] { if (is_in_profile("orig")) { xinfo("this dialog belongs to a orig call\n"); route(EMIT_ORIG_CALL_ENDED); } } Log: | 3(12) INFO: <script>: Managing dialog... for BYE | 3(12) ERROR: *** cfgtrace:dbg_cfg_trace(): request_route=[DEFAULT_ROUTE] c=[/etc/kamailio/kamailio.cfg] l=263 a=24 n=dlg_manage | 3(12) DEBUG: dialog [dlg_hash.c:887]: internal_get_dlg(): ref dlg 0x7f8edda138e0 with 1 -> 3 | 3(12) DEBUG: dialog [dlg_hash.c:891]: internal_get_dlg(): dialog callid='96af5356-4663-4f5d-b6ca-c0d2381c992a' found on entry 16097, dir=1 to-tag='5' | 3(12) DEBUG: dialog [dlg_profile.c:536]: set_current_dialog(): setting current dialog [16097:1304] | 3(12) DEBUG: dialog [dlg_hash.c:1290]: next_state_dlg(): dialog 0x7f8edda138e0 changed from state 4 to state 5, due event 7 (ref 3) | 3(12) DEBUG: dialog [dlg_hash.c:1071]: dlg_ref_helper(): ref op on 0x7f8edda138e0 with 1 from dlg_handlers.c:1799 | 3(12) DEBUG: dialog [dlg_hash.c:1075]: dlg_ref_helper(): ref dlg 0x7f8edda138e0 with 1 -> 4 | 3(12) DEBUG: dialog [dlg_handlers.c:1803]: dlg_run_event_route(): executing event_route 3 on state 5 | 3(12) ERROR: *** cfgtrace:dbg_cfg_trace(): local_route=[dialog:end] c=[/etc/kamailio/kamailio.cfg] l=453 a=16 n=if | 3(12) ERROR: *** cfgtrace:dbg_cfg_trace(): local_route=[dialog:end] c=[/etc/kamailio/kamailio.cfg] l=448 a=25 n=is_in_profile Looking at code I can see that dialog profiles are cleaned on next_state_dlg() when the dialog moves from state 4 to state 5 /* remove the dialog from profiles when is not no longer active */ if(*new_state==DLG_STATE_DELETED && dlg->profile_links!=NULL && *old_state!=*new_state) { destroy_linkers(dlg->profile_links); dlg->profile_links = NULL; } My question for the more experienced guys: is this behaviour by design? Can we change it to only clean profiles at same time we clean dlg_vars for example? Thanks! Andre Barbosa

Hello guys !!! i'm a beginner in kamailio technology and i want to use kamailio http_client module to get data from API, but i got : Access error : Unauthorized Access Denied Wrong Password My user IDs are correct. API's encryption is MD5 (digest Auth ). So i use: modparam("http_client", "authmethod", 2) ... modparam("http_client", "cipher_suites", "ecdhe_ecdsa_aes_128_gcm_sha_256, rsa_aes_128_gcm_sha_256") then modparam("http_client", "cipher_suites", "rc4-md5") Can someone help me please ?

Kamailio 5.4.4 and Siptrace
by pwerspire 20 Apr '21

20 Apr '21

Hi list, I have the following configuration for siptrace: #################### modparam("siptrace", "duplicate_uri", "{{ homer_uri }}") modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_flag", 22) modparam("siptrace", "trace_on", 1) modparam("siptrace", "trace_mode", 1) modparam("siptrace", "hep_version", 3) modparam("siptrace", "hep_capture_id", 2070) ####################### But we saw that local replies from Kamailio in some cases would not appear. For example, Invite is sent to Kamailio and Kamailio replies with a Forbidden, in homer only the Invite and the ACK would appear. So any scenario that the Invite has the final answer locally on Kamailio would not appear the reply in Homer. I tried to use the following modified config: #################### modparam("siptrace", "duplicate_uri", "{{ homer_uri }}") modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_on", 1) modparam("siptrace", "trace_mode", 0) modparam("siptrace", "hep_version", 3) modparam("siptrace", "hep_capture_id", 2070) and in the Request Route: request_route { sip_trace_mode("t"); .... } ####################### With this last configuration, I can see now all the messages (for example the forbidden appears) but we found out a problem with this configuration. In a normal scenario if we have some mapping for example from 487 to 480 in the onreply_route { .... change_reply_status(480,"Temporary unavailable"); ..... } in homer it will appear that Kamailio received the 480 instead of the 487, so basically siptrace is reporting the message after being change instead of the original message received. Any ideas what I need to change on the siptrace to have this correctly working? Thanks for the help, Regards, Tiago

Has anyone got it work with Zoiper and Bria? Thanks and regards Markus
