by Daniel-Constantin Mierla

Hello, Kamailio SIP Server project is organizing another meeting of its developers and community members during November 19-20, 2024 (Tue-Wed), hosted again by sipgate.de in Dusseldorf, Germany. The event is intended to facilitate the interaction between Kamailio developers and contributors in order to offer a convenient environment for working together on several topics of high interest for the project, including writing code for Kamailio and its tools, improving documentation, or discuss about future development. Everyone from the community is welcome to join, developer or user interested in helping the project. Please note we have a limited capacity of seats in the meeting room, the main policy for accepting participants being first come first server. Also, very important to be aware that this is not an event to learn how to use Kamailio. More details about the event, the venue, how to register, are available at: * https://www.kamailio.org/w/developers-meeting/ Looking forward to those two intensive hacking Kamailio days in Dusseldorf!

apt-key deprecation

by tom＠tomlynn.com

When I look at the debian repositories maintained by the project, there are instructions to import the public key of the repository for apt using this command: wget -O http://deb.kamailio.org/kamailiodebkey.gpg | sudo apt-key add - which results in: Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)). gpg: no valid OpenPGP data found. Is there an alternate method that can be posted in the repository that will get better results? Thank you, TL

Setting $du to websocket-secure

by James Browne

How can I set the destination URI for an INVITE to be a websocket-secure destination? Is it possible? Summary I've a proxy with tcp_connection_match=1, but websocket URIs always have transport=ws (never transport=wss) in them, so relaying a call to a WSS connection always fails. I tested running kamailio 6.0.0-dev2 compiled from a commit made this week. This proxy server uses nathelper rather than outbound module. Detail We know that "transport=ws" is used for both WS and WSS. I've a proxy server that receives an INVITE for a WSS destination, and this proxy supports both WS and WSS. This proxy server must have core parameter tcp_connection_match=1 set, and this leads the t_relay() to fail. When an INVITE comes, these are the steps. - The URI is something like sip:user@anonymous.invalid;alias=198.51.100.10~52833~6;transport=ws. - First handle_ruri_alias() removes the alias (which has ~6 in it, for wss) and sets the $du to something like sip:198.51.100.10:52833;transport=ws. - Then loose_route_preloaded() processes the Route header fields and forces the outbound socket to the TLS websocket one. - Then t_relay() fails to relay the INVITE and responds with 477 or 500. If, however, there's a non-TLS websocket connection open to the proxy, the INVITE would be erroneously relayed over that (using the wrong kamailio-side TCP port). I can go deeper with testing if required. I wonder whether this is a bug. James

Suspected memory leak in module ims_registrar_pcscf

by whliu＠citictel.com

Hi, I just tried to send numbers of SIP register to kamailio (release 5.8.2). It is reported that there are some memory leakage in shared memory after the expiry of all the registration sessions. After drill down the code. function save_pending(...) is called. (in ims_registrar_pcscf/save.c). Inside that function, it seems that "sec_verify_params" is not deallocated upon the function completes. Findings: - sec_verify_params uses the result from function cscf_get_security_verify(...) - Function cscf_get_security_verify(...) returns the result of function parse_sec_agree(...) - Function parse_sec_agree(...) returns "params" where "shm_malloc(...)" is called It seems that the memory pointed by 'sec_verify_params' is not further referenced by others. Should shm_free(...) be called when leaving function save_pending(...) in order to free the unused memory of 'sec_verify_params'? Please advice. Thank you. Regards, Hong

Disable topos for a specific peering IP

by Denys Pozniak

Hello! I need to disable topos for one specific SIP trunk (in-out), it looks like it’s enough to use event_route with IP address filtering. But for some reason, the incoming INVITE from the peer still gets processed by topos and I also don’t see a mention of [msg-incoming] in the logs, only this: WARNING: <script>: [msg-outgoing] OPTIONS/you/1.1.1.1 Code snippet: loadmodule "topos.so" modparam("topos", "db_url", DBURL) modparam("topos", "contact_mode", 1) modparam("topos", "header_mode", 1) modparam("topos", "methods_noinitial", "OPTIONS,SUBSCRIBE,PUBLISH") modparam("topos", "dialog_expire", 7210) modparam("topos", "rr_update", 1) modparam("topos", "event_mode", 5) /* 1 - execute event_route[topos:msg-outgoing] 2 - execute event_route[topos:msg-sending] 4 - execute event_route[topos:msg-incoming] 8 - execute event_route[topos:msg-receiving] */ request_route { .... event_route[topos:msg-outgoing] { if ( $sndto(ip) == "1.1.1.1" ) { xlog("L_WARN","[msg-outgoing] $rm/$rU/$sndto(ip) \n"); drop; } } } event_route[topos:msg-incoming] { if ( $si == "1.1.1.1" ) { xlog("L_WARN","[msg-incoming] $rm/$rU/$si \n"); drop; } } # kamailio -v version: kamailio 5.7.1 (x86_64/linux) 1cf389-dirty -- BR, Denys Pozniak

Using a different OpenSSL

by David Cunningham

Hello, We have compiled openssl 3.0.9 from source because it's FIPS validated, and want to use it with Kamailio. The server also has the Ubuntu openssl 3.0.2 package installed. Does anyone know how we can tell Kamailio to use the openssl library in /opt/openssl/lib64, and how we can verify that it really is using it? Thanking you in advance, -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 New Zealand: +64 (0)28 2558 3782
