Info: Issue and PR automatic management
by Daniel-Constantin Mierla 27 Nov '23

27 Nov '23

Hello, during the Kamailio Development Meeting that took place in Dusseldorf earlier this month, one topic was related to administrative tasks related to project development and management, how to simplify/automatize such tasks. To reduce the work load on volunteering contributors, GitHub Actions were already used for various tasks related to project development and management (e.g., automatic builds on commits and pull requests to detect compile errors or code formatting mistakes). In Dusseldorf another task was configured to be managed with GitHub Actions, respectively the check of open issues and pull requests to evaluate the interest of submitters, developers and community users to pursue them. If there is no activity on an issue (potential bug or feature request) or a pull request, after 6 weeks it is marked with the label `stale`. After two more weeks of no activity, the issue or the pull request is marked with the label `expired` and closed. Note that any comment postpones the expire timeline, being considered that there is interest in pursuing the issue or the pull request. Requests for features were already treated in this way: if nobody commits to implement it, it can be closed after one month, but it needed manual work and many were still kept open. Potential bug reports that become very old are hard to tackle if the source code changes or new major releases are out, they might even not be valid anymore. Anyhow, this automatic operations can be reverted if there is still interest in pursuing the specific issues or pull requests. A registered developer can remove labels and reopen a closed issue or pull request. The non-registered-developer contributors have to make a comment that includes the token `/notstale` to remove the label `stale` or includes the token `/notexpired` to reopen a closed item. This new kind of automatic task management might add a little inconvenience because one has to restate the interest from time to time for those items that could not be addressed. However, considering that Kamailio is an open source collaborative project, in order to be fair for those that volunteer to spend time and resources for development of Kamailio, also the users/submitters have to stay engaged, not just report and forget about. The process to automatize tasks related to Kamailio development and administration is work in progress. Everything can be adjusted based on feedback (e.g., time lines), feel free to suggest improvements or new solutions to make things easier for everyone within the project ecosystem.

How to remove record-route and via from a forwarded call?
by Benoit Panizzon 27 Nov '23

27 Nov '23

Hi List Two Kamailio Nodes situation. Node A: Routing Instance. Node B: Registrar Instance. An invite is sent from Node A to B. Customer registered on B is 'busy' as example. B initiates Call Forwarding by adding a Diversion Header and sending the Invite back to A with a new R-URI towards the CFB destination. The Invite sent from B to A still has Node B in it's Record-Route. So all subsequent SIP messages pass via B, which is not needed and cause issue with rtpengine running on B. I attempted to remove_record_route(); when sending the call back to A, but this causes: parse_headers(): bad header field [;lr;ftag=3910078620-883101371> It looks like only the beginning of the RR header is removed leaving back a competely broken line. What is the propper was to remove a node from RR and Via routing?

Re: RADIUS - Can't use extra attributes
by Duarte Rocha 24 Nov '23

24 Nov '23

Hello Daniel, Thanks for the reply. The extra dictionary is already included otherwise an error is thrown and Kamailio doesn't start. However, i realized my mistake now and you were right. I was checking for the extra attributes in a tcpdump and on radius server and i didn't had the dictionary configured on both of them. The extra attributes are in the packet but weren't being listed. One more question. Kamailio doesn't have a way to do a totally custom RADIUS access-request packet right? (Sorry if this opens another thread. I usually just hit reply on the mailing list and let Outlook create the e-mail, but it usually creates another thread and i'm not sure why). Thanks again. Cheers, Duarte

Max-Forwards header missing in OPTIONS keep-alive messages
by Christian Schnell 24 Nov '23

24 Nov '23

Hello, in RFC 3261 (sec. 8.1.1.6) it states about the Max-Forwards header field: > A UAC MUST insert a Max-Forwards header field into each request it originates with a value that SHOULD be 70. > > Source: https://datatracker.ietf.org/doc/html/rfc3261#section-8.1.1.6 When Kamailio sends its OPTIONS keep-alive requests (from the nathelper module I believe), Max-Forwards is missing: > OPTIONS sip:alice@example.com:61266 SIP/2.0 > Via: SIP/2.0/UDP aa.bb.cc.dd:5060;branch=z9hG4bK5124450 > From: sip:pinger@sip.example.com;tag=uloc-6550aa14-7456-2461-6390f173-5fdb4667 > To: sip:alice@example.com:61266 > Call-ID: aba25282-2ca72be1-9d1fd53(a)aa.bb.cc.dd > CSeq: 1 OPTIONS > Content-Length: 0 The user agent library I'm using (libre from baresip) rejects these requests with a "400 Bad Request" response, I looked at the sources and it denies these requests because of the missing Max-Forwards header. Of course this suffices for the keep-alive logic because all that's needed is any traffic in both directions to keep both (potential) NATs open. However you might agree that it does look a bit confusing at first, and the RFC is clear about that. So it's not a bug, but is this behavior intended? Thanks, also thanks for all the great work that has been put into Kamailio. Christian

RADIUS - Can't use extra attributes
by duarterocha91＠gmail.com 24 Nov '23

24 Nov '23

Hello all, I'm currently implementing a Kamailio with RADIUS. I want to send an Access-Request to my RADIUS server and in order to do that i'm using misc_radius module and radius_does_uri_exist() function without any arguments : "if (radius_does_uri_exist()) {" For my module configuration I have the following configurations : "modparam("misc_radius", "radius_config", "/etc/radcli/radiusclient.conf") modparam("misc_radius", "uri_extra", "Sip-Method=$rm")" From what i understand, with this config my access-request should contain the default attributes and Sip-Method Attribute but that is not happening. Only defaults attributes are included. I've tried to run Kamailio with "-ddd" flag for better debug and i only get this error : "1(176) DEBUG: misc_radius [functions.c:615]: radius_does_uri_user_host_exist(): failure". Is there any other configuration that i must do? Thanks for the help. Cheers, Duarte
