"Re: TOPOS (5.1.[23]) breaks PRACK"
by Simone de Blasiis 20 Apr '22

20 Apr '22

Hello, we noticed the exact behaviour on Kamailio 5.5.4 and topos. If we disable topos the UPDATE messages are being recognized as loose in the WITHINDLG route and everything works. When topos is enabled the UPDATE messages fail the loose_route() check and even if we force the record_route() the message is still not being forwarded. I had just posted my own thread here <https://lists.kamailio.org/pipermail/sr-users/2022-April/114710.html> because I didn't see this one. I'll proceed opening an issue on GitHub so we can track this. Best regards Simone

Problems with topos and UPDATE messages
by Simone de Blasiis 20 Apr '22

20 Apr '22

Hello to everyone, we are experiencing some issues with UPDATE messages being sent by the PSTN after an early media announcement. To reproduce the issue I have to call a specific number that has an early media announcement, since it's a paid phone number it has to announce how much it would cost before picking up the call. In this initial part the call is being negotiated in g711a. As soon as the announcement ends, the PSTN sends an UPDATE message containing the new desidered codec from the callee which is g729. At this moment Kamailio doesn't route the UPDATE message to the destination and it actually replies with a 404 message. I've attached a pcap with anonymized IPs to make it harder for bots. Here is a legend for the IPs: - - 12.34.123.123 is Kamailio - 62.23.19.74 is the PSTN - 1.2.130.40 is the client making the call I found a similar report <https://github.com/kamailio/kamailio/issues/2659> in the GitHub issues of the repository and we tried forcing the record_route() as suggested but, as the OP reported in his last message, it's not working. As soon as we disable topos, the UPDATE message is correctly relayed to the caller. In the documentation we can't find anything that could give us a hint on what's happening. Does anyone have any idea on what could be happening? Thanks in advance Simone

rcd using secspid
by Jon Bonilla (Manwe) 20 Apr '22

20 Apr '22

Hi all I've been checking for adding rcd info to te stir/shaken stuff using secspid module. I've only found this thread: https://lists.kamailio.org/pipermail/sr-dev/2021-June/063156.html I'd like to know if someone has working code snippet using this function to create/sign the json containing the rcd and creating the Identity header instead of calling the all_in_one secsipid_add_identity function I'm using now. cheers, Jon -- PekePBX, the multitenant PBX solution https://pekepbx.com

PostgreSQL - module sqlops - working with prepared statements ?
by Chaigneau, Nicolas 20 Apr '22

20 Apr '22

Hello, I'm using sql_xquery from sqlops module to execute requests on a PostgreSQL database. This work fine. Now, for performance reasons, I would like to use prepared statements. I'm wondering if this is possible using sql_xquery. I've looked at the code and documentation, it seems it is not supported. Can you confirm ? If not possible with sql_xquery, is it possible with another existing function ? In the code, I've searched for < PQprepare > / < PQexecPrepared >. These can be found only in < modules/db_postgres/pg_cmd.c >, in function < pg_cmd_exec > which is exported from < modules/db_postgres/pg_mod.c > (see below). I have no idea how to use these though... :/ Any ideas ? /* * Postgres module interface */ static cmd_export_t cmds[] = { {"db_ctx", (cmd_function)NULL, 0, 0, 0, 0}, {"db_con", (cmd_function)pg_con, 0, 0, 0, 0}, {"db_uri", (cmd_function)pg_uri, 0, 0, 0, 0}, {"db_cmd", (cmd_function)pg_cmd, 0, 0, 0, 0}, {"db_put", (cmd_function)pg_cmd_exec, 0, 0, 0, 0}, {"db_del", (cmd_function)pg_cmd_exec, 0, 0, 0, 0}, {"db_get", (cmd_function)pg_cmd_exec, 0, 0, 0, 0}, {"db_upd", (cmd_function)pg_cmd_exec, 0, 0, 0, 0}, {"db_sql", (cmd_function)pg_cmd_exec, 0, 0, 0, 0}, {"db_res", (cmd_function)pg_res, 0, 0, 0, 0}, {"db_fld", (cmd_function)pg_fld, 0, 0, 0, 0}, {"db_first", (cmd_function)pg_cmd_first, 0, 0, 0, 0}, {"db_next", (cmd_function)pg_cmd_next, 0, 0, 0, 0}, {"db_setopt", (cmd_function)pg_setopt, 0, 0, 0, 0}, {"db_getopt", (cmd_function)pg_getopt, 0, 0, 0, 0}, {"db_bind_api", (cmd_function)db_postgres_bind_api, 0, 0, 0, 0}, {0, 0, 0, 0, 0, 0} }; Regards, Nicolas.

Issue when Kamailio is running as a Docker container and the Docker network=overlay
by Steve Wilkins 16 Apr '22

16 Apr '22

Hello, I am attempting to get Kamailio to run as a docker container using a docker network of type network=overlay (everything works great if network=host). The issue is that incoming calls are rejected because of 'connection refused'. I noticed that when running on an overlay network, netstat shows the following => tcp6 0 0 :::5060 :::* LISTEN 10001/docker-proxy-current (Note that I have tcp6 disabled on the server and must leave it disabled) I was attempting to find a workaround for this issue, but have not been successful. Does any one on the board have experience with Docker overlay networks and Kamailio? If so, I would appreciate any suggestions on how to resolve this issue. Thank you,

BLF: modules parameters for specific SIP phones
by Liviu Andron 14 Apr '22

14 Apr '22

Hello, I am working on a BLF (Busy Lamp Field, dialog presence) integration using Kamailio. I am not sure how certain settings can be used on a single generic (any phone) Kamailio instance. * https://www.kamailio.org/docs/modules/devel/modules/presence_dialoginfo.htm… "If the phone does not support this, you can activate this parameter." modparam("presence_dialoginfo", "force_single_dialog", 1) * https://kamailio.org/docs/modules/devel/modules/pua_dialoginfo.html#idm152 "This is a workaround for the buggy Linksys SPA962 phones. SNOM phones work well with the default setting." modparam("pua_dialoginfo", "caller_confirmed", 1) How can I activate these settings only for the phones that have problems? Do I need a different Kamailio instance for each buggy phone that appears from a client ? For example, a Kamailio instance with modparam("pua_dialoginfo", "caller_confirmed", 1) for some (like Linksys SPA962) and the opposite for all the others (like SNOM) ? Thank you,

append new a= in SDP (without rtpengine)
by Lewis Hutchinson 14 Apr '22

14 Apr '22

version: kamailio 5.5.3 Using KEMI Python I have read several posts on this and tried several approaches but can not seem to get it to work. As it stands I am trying to add a=record:on | a=record:off | a=record:pause In the SDP because FreeSWITCH creating the INVITE isn't able to do this in the way required. When it is sent from FreeSWITCH a=record:on is send a=record I have looked at SDPOPS, TEXTOPS and a few others but non of the offer the option to just inject and a= into the SDP body. So as a result I tried a couple of options where the INVITE is created with a=record (unsure why FreeSWITCH wont let us just add :off etc to the end but that's another point that if anyone know would be helpful) and then using replace_body or search_append_body but the result is TEXTOPS is unable to action the request because of a SDP parse error DEBUG: <core> [core/parser/sdp/sdp.c:599]: parse_sdp_session(): ignoring unknown type in a= line: `a=record#015#012a=ptime:20...' Does anyone have any thoughts or tricks on this to give me a few options at ways to handle this? Lewis
