Hello, We’ve been running Kamailio 5.5.0 for a while now and recently ran into an issue where the application buffer would get full and Kamailio has a lot of difficulty keeping up with REG requests. This severely impacted Kamailio’s ability to perform and resulted in many REG timeouts. Running ‘watch netstat -ulpn’ revealed the buffer issue. We usually run the production system at log level INFO (2) and had not ran into any issues in the past. When the buffer issue occurred and after some testing, we discovered that changing the log level to NOTICE (1) was sufficient to bring the system back into operational status. For example, at log level INFO (2) we seem to achieve ~150-200 REG/s while at log level NOTICE (1) we reach ~500-700 REG/s. I did find this article in the wiki and tried using the “-“ in front of the log path but this didn’t seem to help. http://www.kamailio.org/wiki/tutorials/3.2.x/syslog Even writing the logs directly to our external log server and preventing them from being written to the local disk doesn’t seem to alleviate the issue when the log level is set to INFO (2). Does anyone have any experience with this or have any suggestions? We are finding it difficult to scale as a result of this issue. Thank you in advance. Amit

TM Module, avp not present during handling of ack, prack and cancel?

by Benoît Panizzon

Hi List If I'm correctly reading the documentation, all avp variables should exist during a transaction until it's final ACK. ACK, PRACK and CANCEL are part of that transaction. But I seem not to be able to access the content of avp during those messages. Strangely during MANAGE_REPLY of the 487 following a cancel, the avp are present so that 487 clearly is part of the transaction. What am I missing? (Yes, I am still working on mirroring al username (phone number) translations and filtering unwanted header to prevent information leakage, any hints welcome if there is a simpler way to achieve this) -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Kamailio v5.4.9 Released

by Daniel-Constantin Mierla

Hello, Kamailio SIP Server v5.4.9 stable release is out. This is a maintenance release of the old stable branch, 5.4, that includes fixes since the release of v5.4.8. There is no change to database schema or configuration language structure that you have to do on previous installations of v5.4.x. Deployments running previous v5.4.x versions are strongly recommended to be upgraded to v5.4.9 or even better to v5.5.x or 5.6.x series. For more details about version 5.4.9 (including links and guidelines to download the tarball or from GIT repository), visit: * https://www.kamailio.org/w/2022/09/kamailio-v5-4-9-released/ RPM, Debian/Ubuntu packages will be available soon as well. Note: the branch 5.4 is an old stable branch, v5.4.9 being the last planned release out of it, to mark the end of official maintenance. The maintained stable branches are now 5.5 and 5.6, at this time with v5.6.1 being the latest stable release. Many thanks to all contributing and using Kamailio!

Hello, I am planning to release a new version from branch 5.4, respectively 5.4.9, sometime soon, maybe on Friday or Monday. Unless a major regression comes out with this release, this is going to be the last official packaged version from branch 5.4. The latest two stable branches 5.5 and 5.6 will be maintained further. As usual, if anyone is aware of issues not yet reported to bug tracker or missing backports, report them in order to try to get the fixes in this release.

ndb_redis value substitution or escaping spaces

by Brooks Bridges

I am aware of, and have used sucessfully, the %s substitution option in redis_cmd, however when trying to do 4 values I'm getting a parse error about too many arguments. A review of the module's source appears to indicate that there is a hard limit of 3 substitution values when using this method. Is there a suitable workaround anyone has for this to enable insertion of values with spaces in them that won't get interpreted by Kamailio itself? Escaping the value, even by using $_s to eval a dynamic string, ends up with Kamailio itself apparently trying to parse the escape and breaking things further. Thanks!

New feature: #!ifexp - conditional preprocessor blocks

by Daniel-Constantin Mierla

Hello, a new feature has landed to Kamailio devel version, bringing in more flexibility for preprocessing of the kamailio.cfg file. It is about #!ifexp, which allows to evaluate an expression created with defined IDs, string and number values. Based on evaluation result, being true or false, parts of the config file can be enabled or disabled. An extensive number of operators can be used in expressions, such as: +, -, *, /, ==, !=, <, >, <=, >=, ||, &&, etc. The evaluation is done using snexpr (https://github.com/miconda/snexpr), which was embedded inside Kamailio code. Here are some simple kamailio.cfg examples: #!ifexp KAMAILIO_VERSION >= 5006000 loadmodule "tlsa.so" #!else loadmodule "tls.so" #!endif #!ifexp MOD_xlog && (OS_NAME == "darwin") xlog("running on MacOS\n"); #!endif Documentation and more examples can be found on the wiki portal at: - https://www.kamailio.org/wikidocs/cookbooks/devel/core/#ifexp Testing would be appreciated, feedback can be addressed to sr-users mailing list!

evapi_async_relay() and workers

by Alex Balashov

Hi, When a transaction suspended by evapi_async_relay() is resumed, in which child processes is it resumed? Is it in the dedicated “EVAPI RELAY” workers defined by the ‘workers’ modparam to ‘evapi’? If this is so, just trying to work out the concurrency implications and the optimal size for the worker pool for maximal throughput. It sounds, at first glance, like it should be roughly similar to the sizing considerations for listener children. Thoughts welcome!

Kamailio + RTPEngine SIP Proxy...

by Jerry Kendall

Hi There, It's been a few years since I joind the group and I have watched and learnt and played but, I am stuck... I have searched hi & low but I can't seem to find what I am looking for. Is is do-able to have SIP Phones proxy through Kamailio/RTPengine and have the connection relayed to a freeswitch system where all the work is done. I need to have Kamailio act as proxy ONLY - no need to do AUTH, and I need Kamilio to have the RTPEngine have the media but only as proxy. I have FreeSWITCH doing all the IVR/VM/CONF/etc.... So: 1) The SIP Phone sends everything to the Kamailio system, the Kamailio system will relay everything to the FreeSWITCH system (requests and replies) 2) The FreeSWITCH system will send everything to the Kamailio system which will relay everything back to the SIP Phone (requests and replies) 3) The SIP phones are behind NAT 4) The Kamailio and FreeSWITCH systems are on the public internet with public IP addresses I have found a few sample kamailio.cfg files but, I can get REG to make it through but no SUBCRIBE wont get NOTIFYs back, etc... I seem to get parts but not all the way. If this is doable, and I assume it is, is there a config file someone can share with me? or point me to? Jerry
