[Dialog Module] questions about early_timeout param
by Abdoul Osséni 08 Oct '23

08 Oct '23

Hello all, Can you please clarify part of the following doc for me? -- 6.7. early_timeout (integer) The timeout (in seconds) after which the dialogs in unconfirmed or early state (no final response received) are destroyed. * Default value is “300 (5 minutes)”. * *Example 1.7. Set early_timeout parameter* ... modparam("dialog", "early_timeout", 180) --- In the case where Kamailio acts as an SBC, will kamailio send a SIP BYE message to both devices (UAC and UAC)? Or Can Kamailio send a BYE message to both parties when timer b has expired? If yes, how to do it? Regards Abdoul

kamailio Behind nat. How Record-Route should be added ？
by 城门虾米 08 Oct '23

UA(192.168.0.11) received 183, find Record-Route(36.140.122.12) then send ACK to 36.140.122.12(Kamialio public ip) not 192.168.0.2(kamailio internal ip), so Kamailio can't receive ACK. this is my config，192.168.0.11 -> Kamailio -> Other SBC(public ip) function ksr_request_route() if KSR.is_INVITE() then KSR.rr.record_route(); KSR.nathelper.fix_nated_contact() end end This question has been bothering me for a long time, help me [cid:d1ec74be-1c33-406e-80d5-68663d1cd21f] [cid:bda00d0d-e6e6-4dc9-9462-141ad42b09b8]

uac_req_send + evroute + crash
by Dr. Barabás Péter 06 Oct '23

06 Oct '23

Hi All, I use kamailio In front of Asterisk and kamailio needs to refresh registrations periodically towards Asterisk to ensure the availability of users from Asterisk side. I use uac module and call uac_req_send() for sending REGISTER requests. I set $uac_req(evroute)=1 The event_route[uac:reply] is called fine, but in kamailio logs I see the next lines: CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f114995ada8), called from uac: uac_send.c: uac_send_tm_callback(860), first free uac: uac_send.c: uac_resend_tm_callback(732) - ignoring After some time, kamailio has crashed. CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f114995ada8), called from uac: uac_send.c: uac_send_tm_callback(860), first free uac: uac_send.c: uac_resend_tm_callback(732) – ignoring CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 34 ALERT: <core> [main.c:774]: handle_sigs(): child process 1407950 exited by a signal 6 Any idea that is it a bug or I use something wrong in config? Thanks in advance! Péter Barabás

Crypto module AES algorithm details
by Jayesh Nambiar 04 Oct '23

04 Oct '23

*Hello,* I am running kamailio-5.3.4 on one of my setup and I intend to use the crypto module in the same. I wanted to understand the following details when the module is used: I understand it uses the AES algorithm, is that correct? Does it use AES 128, 192 or 256 bit algorithms? Does it use CBC or ECB mode for AES? The 5.3 version does not have an parameter for init-vector, so does kamailio use any init vector internally in this case? When i compared the encrypted text that kamailio produces and the ones available online, they were producing different outputs even when same shared secret was used. Hence asking for more clarification PS: Upgrading kamailio is my very last option as this is one af an old setup which only needs this feature without much changes. Thanks for any valuable response. *-- Jayesh*

error in parsing HTTP messages
by sigxcpu＠gmail.com 02 Oct '23

02 Oct '23

Hello, In reference to this issue https://github.com/kamailio/kamailio/issues/3081 I've been advised to set http_reply_parse to "no" which I did (and it is the default value anyways). # grep http_reply_parse /etc/kamailio/kamailio.cfg http_reply_parse=no After setting this, I still get these parsing errors: { "idx": 23, "pid": 102, "level": "ERROR", "module": "core", "file": "core/parser/msg_parser.c", "line": 748, "function": "parse_msg", "logprefix": "", "message": "ERROR: parse_msg: message=<HTTP/1.1 100 Continue\r\n\r\nHTTP/1.1 200 OK\r\ndate: Wed, 26 Jul 2023 16:43:19 GMT\r\ncontent-length: 224\r\ncontent-type: text/plain; charset=utf-8\r\n\r\n{\"result\": {\"ruri\":\"\",\"fU\":\"\",\"tU\":\"\",\"privacy\":\"\",\"identity\":\"\",\"error\":{\"code\":0,\"message\":\"\"},\"mb\":\"\",\"Headers\":null,\"encrypted\":\"\",\"sipsScheme\":\"\",\"attestation\":\"\",\"authUser\":\"\",\"authPassword\":\"\",\"disableStirShaken\":\"\"}}>" } Is there anything that I am missing beyond setting that parameter? Thank you, Alexandru
