named account with multiple numbers
by beer Ll 03 May '21

03 May '21

Hi I have a configuration with sip accounts which authenticate with the real name of the customers ex: customer1(a)sip.myvoip.dev customer2(a)sip.myvoip.dev ... INBOUND call of multiple numbers are connected with alias_db to the accounts ex: +331234567890 | sip.myvoip.dev | customer1 | sip.myvoip.dev | +331234567891 | sip.myvoip.dev | customer1 | sip.myvoip.dev | +341234567893 | sip.myvoip.dev | customer2 | sip.myvoip.dev | +341234567894 | sip.myvoip.dev | customer2 | sip.myvoip.dev | ... and all works perfectly. OUTBOUND call after authentication with the username kamailio change the caller id and the ip of my ISP-SIP-TRUNK to relay the call with the correct CID for the ISP using the variable $fn (display name in the From header) [SIP-GW-ISP] { #out with ISP route(CID); $ru = "sip:" + $rU + "@" + "IP_ADDRESS_MY-ISP"; route(RELAY); exit; } ROUTE[CID] { $var(caller) = $(fn{re.subst,/"//g}); uac_replace_from("$var(caller)","sip:$var(caller)@$fd"); } Is possible do it with a different approach for example using Remote-Party-ID , PPI P-Preferred-Identity ? Is possible to check if the customer uses the correct outbound number present in the alias_db table ? ex for customer1 only +331234567890 or +331234567891 numbers many thanks Luca

by Henning Westerholt 03 May '21

03 May '21

Hello, the "new in Kamailio 5.5.x" document has been updated. Again, a really impressive set of changes that lead to this release: Over 1350 commits have been done in the last development period from over 70 individual contributors. You find the document at the usual place in our wiki: https://www.kamailio.org/wiki/features/new-in-5.5.x Many thanks to everybody who contributed to Kamailio. Help in updating the documentation (e.g. core cookbook, pseudo-variable and transformation section) in the wiki is really welcome, as some content is probably still missing there.

Dialog server behind proxy and ka_timer/ka_interval
by David Villasmil 30 Apr '21

30 Apr '21

Hello guys, So i have a setup where client | V (WS) [proxy (no dialog tracking)] | V [dialog server] | V [proxy (no dialog tracking)] (WS) | V client I'd like to know when any of the clients are not available (i.e.: crashed, shutdown unexpectedly. etc), so i enabled on the dialog server ka_timer/ka_interval. I see the OPTIONS going to the proxy when the call starts, and the proxy replying with 200 OK. If i shutdown the client, i see the OPTIONS still going, but the proxy is still responding. I assume the Proxy (kamailio) is simply responding to an OPTIONS message and not actually trying to resend it to the client. Is there anyway of doing this or something better to accomplish the same thing? Thanks! David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Development for v5.5.x is frozen
by Daniel-Constantin Mierla 30 Apr '21

30 Apr '21

Hello, the formal notification that the development for the next major version 5.5.0 is now frozen. The focus has to be on testing the master branch. Also, the master branch should not get commits with new features till the branch 5.5 is created, expected to happen in 2-4 weeks, a matter of how testing goes on. Meanwhile, the commits with new features in the C code can be pushed to personal branches, new pull requests can still be done, but they will be merged after branching 5.5. Can still be done commits with documentation improvements, enhancements to related tools (e.g., kamctl, kamcmd), merging exiting pull requests at this moment, exporting missing KEMI functions and completing the functionality of the new modules added in 5.5. Once the branch 5.5 is created, new features can be pushed again to master branch as usual. From that moment, the v5.5.0 should be out very soon, time used for further testing but also preparing the release of packages. If someone is not sure if a commit brings a new feature, just make a pull request and it can be discussed there on github portal or via sr-dev mailing list. A summary of what is new in upcoming 5.5 is going to be built at: * https://www.kamailio.org/wiki/features/new-in-5.5.x Upgrade guidelines will be collected at: * https://www.kamailio.org/wiki/install/upgrade/5.4.x-to-5.5.0 Everyone is more than welcome to contribute to the above wiki pages, especially to the upgrade guidelines, to help everyone else during the migration process from v5.4.x to 5.4.x.

Hi all, We are using RTPProxy with Kamailio on Amazon EC2. Everything seems to work fine, but once in a while we would get IPs like: 10.3.14.156 and no port. Any idea what is wrong? Thanks.

To-Tag on Register Refresh method
by Duarte Rocha 28 Apr '21

28 Apr '21

Hello all, I'm using Kamailio as a registrar and i have an endpoint that sometimes sends a REGISTER method with a To-Tag when refreshing its regist. My code on this proxy shares many similarities with the default kamailio.cfg configuration file. On that occasion Kamailio answers with a 404 - Not Here since it treats it as a in-dialog request which fails the loose_route check. Why would a CPE send a REGISTER with a To-Tag? Why is a REGISTER with a To-Tag rejected by Kamailio when it could otherwise be a successful REGISTER? Is this behaviour noncompliant with the SIP protocol? I thought about making an exception in the code and having this register following the same path as a register without to-tag, but i don't know if that is unsafe and/or noncompliant with the protocol. Best Regards,

In case of topology: A - P1 - P2 - P1 - B is the idea to use in P1 context "in" when initial request comes to P1 from A or B and context "out" when initial request comes to P1 from P2? Does context need to be set in replies too? If so, is reply context the same as the corresponding request context? And finally, does context need to be set for in-dialog requests/replies the same way as for initial requests? -- Juha

how to turn off memory debug messages?
by Juha Heinanen 26 Apr '21

26 Apr '21

In config file I have: debug=2 mem_summary=0 Still I get 3400+ memory related syslog message when Kamailio terminates due to sqlops not been able to connect to mysql server. According to core cookbook, memdbg and memlog should not be active when their values are greater than debug value (they default to 3) and mem_summary=0 should disable printing of memory debugging info. What is it that I'm still missing? -- Juha

[ANNOUNCE]: sipnagios, a Nagios Plugin to check Call Quality in SIP VoIP (compatible with checkmk, etc)
by Giovanni Maruzzelli 23 Apr '21

23 Apr '21

Hello fellow VoIPers and RTCers, on GitHub there is an early release of sipnagios, opensource. check it out: https://github.com/gmaruzz/sipnagios sipnagios is a Nagios Plugin to check Call Quality in SIP VoIP (compatible with checkmk, etc) sipnagios implements the Nagios plugin API for monitoring and performance data.sipnagios.c is a modification of the original siprtp.c sample in pjproject distribution. Supposedly, it works on Linux, Windows, and anywhere you can compile pjproject on.It makes a call, checks all the various resulting values (mos, rtt, pdd, tta, jitter, packet loss, bytes and packets transferred, and so on). It verifies these values are included into acceptable, warning, or critical ranges.If the call has gone well, sipnagios print performance data for Nagios graphs, and returns 0.If the call fails, or if its measured values are not inside acceptable ranges, it exits with Nagios conventional WARNING or CRITICAL values. mos calculation is scraped from Julien Chavanton work (VoIP Patrol, on GitHub too) I can't even understand :) (merci Julien!) Enjoy! -giovanni -- Sincerely, Giovanni Maruzzelli OpenTelecom.IT cell: +39 347 266 56 18

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.

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

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
