KAMI python3 and python3s not working / reloading

Hello, I've started testing/learning KEMI and decide to use python3(s). I'm using default config with kamailio-basic-kemi-python3s.py (just deleted a couple of routes for simplicity). First thing I noticed is that reloading is not working. I've changed simple log line and did kamcmd app_python3s.reload. I'm compiling from source (inside Docker container, Debian bookworm as base), and have noticed it stopped working after thees commits for python3s: 62b4ee4a0d0b62b35c8bdf67e5daf9cbe9a28499 … [View More]

nethelper module - need clarification on how to handle uri alias on location contacts.
by Benoît Panizzon 20 Dec '24

Hi Gang When a CPE behind nat registers, I have the alias added to the AOR contact. It has format ip~port~transport Let's say: bob@1.2.3.4:5060;alias=5.6.7.8~7777~1 On an invite to that CPE behind nat, the contact is retrieved from the location record and I assumed I could call handle_ruri_alias in the branch route to that CPE and this would sent the call to that ip port via transport in the alias. I observe that the port is not taken into account. The INVITE to bob is sent to ip 5.6.7.8 … [View More]

Multiple Branches and 3xx Status Codes
by Christian Berger 17 Dec '24

17 Dec '24

Hi, we have the following situation: Multiple UAs are subscribed to the proxy and get INVITEd via parallel forking. Now one of the UAs sends us a 302 status, we would like to handle this like a failure. So we'd like to CANCEL all the other branches, and forward the 302 status to the original INVITE. We have tried t_reply("302", "$T(reply_reason)") in the response, which almost solves this, however we cannot pass the required headers form the 302 response in it. BTW, could there have … [View More]

Hello, I propose to aim freezing the development for 6.0.x series at the end of the 16th of December 2024 (Monday). New features that one wants to get in this release series have to be pushed to git repository or pull requests made for them. Afterwards usually follows a 4-6 weeks of testing till the first release 6.0.0. Unfreezing will happen earlier, after the first weeks of testing when the 6.0 branch will be created.

How to remove rr param on a reply?
by Benoît Panizzon 13 Dec '24

Hi Is there a way to remove an param from the top most rr header? I add a rr param towards the B CPE to store some information which is sent back on the rr header of the reply from B. So far this is what is intended and I also get this param in subsequent route headers from messages created by B and as the route header are remove towards A, this works fine. Unfortunately, in a case of a reply, the parameter is passed to A which is then sending back the param in the route header which would … [View More]

registrar / usrloc / tm => 'load balanced' serial forking?
by Benoit Panizzon 13 Dec '24

Hi List With the dispatcher module, you can use different ways of load balanced and weighted serial or parallel forking. Is there a corresponding way to achieve load balanced serial forking to a destination set loaded from registered locations? Use case: Customer with a high availability set-up has two redundant PBX registered to the same AoR. Calls can not be sent in parallel as this would generate two concurrent calls to the end device but call should be distributed evenly between the … [View More]

HTTP_CLIENT timeout
by Sergio Charrua 13 Dec '24

Hello all! For a STSH project, kamailio is making HTTP requests to a middleware (REST API) using HTTP_CLIENT module. I have set the parameter "timeout" to 2 second, but this increases PDD to too high levels, so I have set it to 1 second. Problem is that 1sec is also too high! The parameter only accepts integer values, so no way to set this to 0.5sec. I thought of having a way for kamailio to be aware that HTTP node #1 is down, so next request it will use HTTP node #2 instead. And once in a … [View More]

uneven load distribution after gw goes down?

Hello guys, I'm seeing the dispatcher module used with ds_select_dst($avp(dsdst), "0") is distributing the calls to a failing gw, to the next available gw instead of distributing it. When a gw fails and has been marked as inactive, shouldn't it be taken out of the list and the list recomputed? is this not the case?

WS and rtpengine_manage
by Knserbrave 09 Dec '24

09 Dec '24

Hi Kamailio Community, When testing rtpengine_manage and websockets, I noticed that if the rtpengine table in the database is not used, a new websocket is created for every call for a given dialog. That is, when an INVITE is received, an offer is sent to rtpengine. When the 200 OK or 18[3|0] is received, an answer is sent. However, the WS identifier often changes and as a result the request is not sent over the same websocket. This is problematic particularly when using FQDNs in the Kamailio … [View More]

Potential Bug in Kamailio: Base64 Decode Transformation Not Working in Lua but Works in kamailio.cfg
by Dirk Brouwers | CM.com 28 Nov '24

Dear Kamailio Developers, I am writing to report a potential bug in Kamailio's handling of base64 decoding when using the Lua scripting interface (app_lua). It appears that base64 decoding behaves inconsistently between Lua scripts and kamailio.cfg. When using `$(var(encoded_json){s.decode.base64t})` in kamailio.cfg, where $var(encoded_json) contains the encoded base64 string: `eyJmb28iOiJiYXIifQ` it decodes to the correct `{"foo":"bar"}`.

"Intermittent Issue: Kamailio Presence Server Not Generating NOTIFY Packets"

Hi We have FreeSWITCH and Kamailio presence servers set up. FreeSWITCH sends XML RPC messages to the Kamailio presence servers for PUBLISH operations, and we receive 200 OK responses in return. These responses include the SIP-ETag and Expires headers. However, the Kamailio presence server is not consistently generating NOTIFY packets. This issue seems to occur randomly. Can you please suggest this for presence servers. Thank you in advance.

TM-Module, ignoring

Hi, we would like to replicate a SIP-message ("REGISTER" in our case) to a set of nodes for further asynchronous processing. The message is already processed on the local Kamailio. We thought about using the tm-module in conjunction with the dispatcher module so we can reliably forward the message. This seems to work, however we get a new problem: Kamailio forwards the response it gets from those nodes. When we drop the response in the reply_route, it gets dropped before TM can see it. … [View More]

Hi, I have recently migrated from Kamailio 5.2.5 to Kamailio 5.5.7. After a migration, the Kamailio crashed. Also, there were a lot of errors and warnings. Can someone help me to understand why this happened and what could be the solution?

SIP NOTIFY over TLS fails
by dries＠degendt.com 15 Nov '24

15 Nov '24

Hi all I've installed a custom presence_dkfs module (https://github.com/tombeard/presence_dfks) in an effort to make our Grandstream devices (connected over TLS) display a server set callforward using Broadsoft's Device Feature Key Sync. The module was installed succesfully, but it appears that the NOTIFY upon SUBSCRIBE cannot be sent over TLS. This part seems to use the default presence module however so I'm taking my chances here to ask for some advice. I have already disabled … [View More]

dlq_req_within() usage for 3pcc-style reinvite media setup
by Alex Balashov 14 Nov '24

14 Nov '24

Hi, I am trying to use dlg_req_within() for a 3pcc-style call setup, to set up media via a reinvite: 1. Store original SDP offer from caller in $dlg_var()s; 2. Later, after e2e ACK is processed for initial INVITE transaction, send reinvite to callee using dlg_req_within(). I call rtpengine_offer() and feed it the original SDP offer (via read_sdp_pv modparam), and take the RTPEngine-transformed SDP and feed that to dlg_req_within(): dlg_req_within("callee", "INVITE", "application/sdp", "$… [View More]

Function sdp_get gets extra blank line (when MIME is used)
by James Browne 05 Nov '24

05 Nov '24

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.

Re: Dealing with flood of invalid SIP messages

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
