Info: Donating To Kamailio Project
by Daniel-Constantin Mierla 07 Apr '25

07 Apr '25

Hello! Over the years, there have been discussions about what options could be made available to donate to Kamailio project in order to support its required infrastructure, administrative or development of complex components. Creating a foundation or using a crowdfunding platform have been explored, trying to take in consideration the needed man power and overhead, the transparency and accountability. To move forward on this matter, the Kamailio management team has decided to use Open Collective, with the fiscal host Open Collective Europe, as the platform for accepting and managing donations, more details, including the link where donations can be made, are published at: - https://www.kamailio.org/w/donations/ The donations should target either the support of project administration or the development of new feature, therefore before donating it is recommend to email to <management [at] lists.kamailio.org> providing some details about the scope of your donation. We also plan to discuss about it at the next Kamailio World Conference: May 12-13, 2025, organized again in Berlin, Germany, where many developers and members of the management board and our community get together, being a good opportunity to clarify and decide how to use the donations. More details about the event at: - https://www.kamailioworld.com Thanks for flying Kamailio! Cheers, Daniel -- Daniel-Constantin Mierla (@ asipto.com) twitter.com/miconda -- linkedin.com/in/miconda Kamailio Consultancy, Training and Development Services -- asipto.com Kamailio World Conference, May 12-13, 2025, Berlin -- kamailioworld.com

[kamailio/kamailio] Problems with ims_ipsec_pcscf and closed tcp connections (Issue #4138)
by Atanas Bakalov 05 Apr '25

05 Apr '25

### Description Let's assume we have a MO call from UE to P-CSCF that's over ipsec. Let's assume the picked ports are like UE(6101) -> P-CSCF(6100) We have also set tcp_connection_lifetime to be 20 sec. 20 sec after INVITE connection is RST from Kamailio as expected. Then ( > 20sec later) an INVITE response comes from B side, and must be delivered to the UE. Kamailio opens a new connection and tries to establish a connection from 5060 (standard port)->6101 instead of 6100(P-CSCF) -> 6101(UE). IPSEC associations are not engaged and UE does not handle the request properly. ### Troubleshooting #### Reproduction #### Debugging Data #### Log Messages #### SIP Traffic ### Possible Solutions The IPSEC module should re-open the tcp connection if it sees it's been dropped as core module has no awareness of IPSEC. * **Operating System**: All -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4138 You are receiving this because you are subscribed to this thread.
