Hello Christoph, Kamailio is providing a lot of different functions. Some of these functions could be used to implement a network element with features which are forbidden in the RFC 3261 and/or other relevant RFCs. One of the most prominent examples is e.g., rewriting of From and To headers. I

[SR-Users] Re: RADIUS ACC - Interim Updates

Hello, not exactly what you are looking for, but you could switch to diameter and use ims_charging, which supports this kind of interim updates. Cheers, Henning > -Original Message- > From: Duarte Rocha via sr-users > Sent: Montag, 4. März 2024 18:20 > To: sr-users@lists.kamailio.org

[SR-Users] Re: Clarification on pv_www_authenticate

Hello, For details obviously one need to check in the code. But the error code -1 is usually the default error code and used for topics related to the execution of the service (problems in IO, problems allocating memory and so on). It’s also used as a catch-all error when no more specific error

[SR-Users] Re: [sr-dev] Re: Roadmap to next major Kamailio release series v5.8.x

Hello Richard, thank you, really helpful. Regarding the cdp module, we could provide some access to a test setup. A colleague will contact you about that. Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ Kamailio services – https://gilawa.com From: Richa

[SR-Users] Re: How to keep SIP messages small, possibly below fragmentation limit?

Hello, one really effective way is the topos module. If you can not use this, you could switch to compact sip header. This way you save some bytes per header-field. But this is something that needs to be supported from the user agent as well. You could remove not needed headers and SDP inside t

[SR-Users] rpm kamailio git master version

Hello, just a question about the https://rpm.kamailio.org/ repository, especially regarding git master builds. It seems that the git master build there was updated last autumn. It would be great if it could be updated, now as we want to test for the coming release. Thank you, Henning Westerho

[SR-Users] Re: Dispatcher ping: "binding to source address X.X.X.X:XXXX failed: Address already in use" for TCP and TLS destinations

Hello, we also observed this going from an older release to 5.7.x this week. It seems to be harmless, but its generating indeed a lot of warnings. Cheers, Henning > -Original Message- > From: Jardar Leira via sr-users > Sent: Donnerstag, 15. Februar 2024 22:30 > To: sr-users@lists.kam

[SR-Users] Re: Kamailio as a Presence server only

Hello, you can find the tables and their mapping to the modules e.g. here: https://kamailio.org/docs/db-tables/kamailio-db-5.6.x.html The subscriber table is usually used for authentication purposes in kamailio. Cheers, Henning > -Original Message- > From: djcsalvador--- via sr-users

[SR-Users] Re: Kamailio as a Presence server only

Hello, regarding your questions: 1. Besides from the Kamailio core, you only need to use the modules that are actually necessary for your configuration. There are over 220 modules, so they are of course not always used. 2. Can't comment with too much detail here, but generally speaking, Kamail

[SR-Users] Re: Reject TCP SYN

Hello, what about e.g. just using something like iptables, nftables etc..? iptables -A INPUT -p tcp --syn --destination-port -j REJECT --reject-with icmp-host-prohibited Cheers, Henning From: David Villasmil via sr-users Sent: Donnerstag, 8. Februar 2024 14:28 To: Kamailio (SER) - Users Mai

[SR-Users] Re: usrloc database duplicate keys issue

Hello Benoit, somehow the usrloc internal record id got duplicated. Are you seeing this error frequently or just on some occasions, like the restart you mentioned? You can try to activate this parameter: https://kamailio.org/docs/modules/5.7.x/modules/usrloc.html#usrloc.p.db_insert_update Cheers

[SR-Users] Re: usrloc database duplicate keys issue

Hello, are there more specific errors e.g. from the db_mysql module? Otherwise enable query logging or checkout the DB error log might help you here. If you run Kamailio in debug mode you will also see all the queries on that side. Cheers, Henning -- Henning Westerholt – https://skalatan.d

[SR-Users] Re: How to assign xavp array to htable?

Hello, just for completeness, the htable module also offers the possibility to read values (at startup and/or triggered from a command) from a database. Especially for values that did not change to often this is a good option. Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog
