[db_unixodbc] how to specify the database with unixodbc？

by 17603019528＠163.com

Hi Dear Community, I want to use db_unixodbc to connect to the dm8 database. Although I use Opensips, I found that this module db_unixodbc, Kamailio and Opensips are the same.

Draining TCP/TLS SIP sessions from Kamailio and media sessions from RTPEngine

by Evgenii Buchnev

Hi Dear Community, Would appreciate your input into where to look further to explore my options and would be good to learn your experience with the following. There are many active-active kamailio nodes behind tcp load balancer. On the same VM with each Kamailio there is an instance of RTPEngine to manage Media/Transcoding/Etc for that Kamailio. This scales UP easily - new nodes just added behind tcp load balancer. To be able to scale down and/or update node configuration - I'd like to be able to drain sessions/calls properly and pass any active calls from current Kamailio and RTPEngine to other nodes. DMQ is not yet in place, although it's planned. What would be proper ways of migrating RTP sessions to other RTPEngines? Caveats? Also wonder how properly a tcp/tls based SIP session can be passed to another Kamailio? Thank you in advance for your input. Evgenii Buchnev

Roadmap to v6.0.0 - the next major release

by Daniel-Constantin Mierla

Hello, about 8 months since the last major release v5.8.x, therefore it is the time to plan a bit the next steps for getting v6.0.0 out. The Kamailio Developers Meeting is schedule in Dusseldorf, Germany during November 19-20, 2024, where we expect to push out a consistent number of updates. Then maybe we can wait for another 2 weeks or so to settle down/finish those updates. After that, if no other new features are planned by developers in short term, we can enter the testing phase, so the new major version can be released during the second part of January 2025 or first part of February 2025. Therefore, if you have new features under development that might require more than 1-1.5 months from now, and you want to get them in v6.0.0, let us know to plan properly. Other time lines suggestions to get to v6.0.0 are also welcome!

SNMP setup

by Sergio Charrua

Hi all! I am having difficulties setting up SNMP, and mostly to figure out if what I have setup is correctly configured. This is what I have on Kamailio (5.8.2), which is set as stateless and as a redirect server (simply put, it receives INVITE from SBC, gets a route from routing services, modifies Contact header, and replies to SBC with 300 Multi Choice with new contact header): loadmodule "db_mysql.so" loadmodule "db_cluster.so" loadmodule "http_client.so" loadmodule "jsonrpcs.so" loadmodule "kex.so" loadmodule "corex.so" loadmodule "sl.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "textops.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "jansson.so" loadmodule "snmpstats.so" loadmodule "file_out.so" loadmodule "ctl.so" loadmodule "permissions.so" loadmodule "xhttp.so" loadmodule "xhttp_rpc.so" # ---- SNMP Stats params ---- modparam("snmpstats", "sipEntityType", "proxyServer") modparam("snmpstats", "sipEntityType", "redirectServer") modparam("snmpstats", "sipEntityType", "other") modparam("snmpstats", "snmpgetPath", "/usr/bin/") modparam("snmpstats", "MsgQueueMinorThreshold", 1) modparam("snmpstats", "MsgQueueMajorThreshold", 1) modparam("snmpstats", "dlg_minor_threshold", 1) modparam("snmpstats", "dlg_major_threshold", 1) modparam("snmpstats", "snmpCommunity", "kamailio") I have set the *_minor_threshold values to bear minimum.

Function sdp_get gets extra blank line (when MIME is used)

by James Browne

The sdp_get() function from sdpops returns an extra blank line sometimes, which looks like a bug to me. When I have an SDP that's in MIME, there's an extra newline at the end of the extracted SDP. Here's a sample config. I use 5.8.1 for testing. #################### #!KAMAILIO listen=udp:203.0.113.57:5060 debug=1 loadmodule "sdpops" loadmodule "pv" loadmodule "xlog" request_route{exit;} reply_route { sdp_get("$avp(sdp)"); xlog("L_NOTICE", "[$ci] The SDP is [$avp(sdp)].\n"); } #################### Here are two sample SIP-message bodies. #################### v=0 o=PCD 1730 1730 IN IP4 198.18.114.148 s=PCD c=IN IP4 198.18.114.148 t=0 0 m=audio 29426 RTP/AVP 0 a=rtpmap:0 PCMU/8000 #################### #################### --e61e7a6a-16a2-46c0-adbb-a41ba86d32a2 Content-Type: application/sdp Content-Length: 130 v=0 o=PCD 1730 1730 IN IP4 198.18.114.148 s=PCD c=IN IP4 198.18.114.148 t=0 0 m=audio 29426 RTP/AVP 0 a=rtpmap:0 PCMU/8000 --e61e7a6a-16a2-46c0-adbb-a41ba86d32a2-- #################### When the first body is received, the xlog correctly ends with this. m=audio 29426 RTP/AVP 0 a=rtpmap:0 PCMU/8000 ] with length 130 When the second body is received, the xlog incorrectly ends with this, which has an extra newline in it. m=audio 29426 RTP/AVP 0 a=rtpmap:0 PCMU/8000 ] with length 132 According to RFC2046, "The CRLF preceding the boundary delimiter line is conceptually attached to the boundary", but it looks like kamailio has a bug that incorrectly processes this.

Simultaneous INVITE responses from multiple branches

by Anton Yabchinskiy

Hello, In our system we've encountered the following situation. There's a Kamailio proxy and a few REGISTER'ed devices behind the proxy. When there's an INVITE to these multiple devices, two of them simultaneously answer the call. Kamailio proxy accepts the first 200 OK from one of the devices and tries to CANCEL all other branches. But the second 200 OK device have already responded OK and doesn't acknowledge the CANCEL. So, there's now one established dialog with media, and another "established" one neither having media nor being correctly terminated. Looks like the similar scenario is described in section 3.1.2 of RFC 5407 (Example Call Flows of Race Conditions in the Session Initiation Protocol (SIP)). Is it possible to mitigate such scenarios in a Kamailio proxy? E.g., is it possible to send an additional BYE to these CANCEL'led branches? In current configuration, Kamailio proxy retrieves contacts with registrar:lookup() and does parallel forking with tm:t_relay().

Re: Dealing with flood of invalid SIP messages

by Juha Heinanen

I gave APIBAN a try. After a few days, no requests were banned by APIBAN, but during the same period, lots of request were banned by other checks in my config. That made me wonder if APIBAN really is effective. -- Juha

Error opening Kamailio's FIFO /run/kamailio/kamailio_rpc.fifo

by matilopi17＠gmail.com

Hello, This is kamailio version 5.8.2 and we`re having this issue every now and then. The error displayed is: ** ERROR: Error opening Kamailio's FIFO /run/kamailio/kamailio_rpc.fifo ** ERROR: Make sure you have loaded the jsonrpcs module and set FIFO transport parameters The problem is that the FIFO file /run/kamailio/kamailio_rpc.fifo doesn't exist, even though the "jsonrpc" module is in the Kamailio configuration, and the file is created when Kamailio service is restarted. But as mentioned, after few days the issue is repeated. I`ll appreciate any suggestion or advice of what I should check. Thank you!
