Kamailio v5.4 install
by Jewna 21 Jan '21

21 Jan '21

I'm having a problem installing kamailio 5.4 using the following guide https://kamailio.org/docs/tutorials/5.4.x/kamailio-install-guide-git/ . I have a debian 10.7 machine where I install default-mysql-server package for the database. After that I follow the install guide and everything goes smoothly until I have to install the init.d scripts. 1. I do "cd /usr/local/src/kamailio-5.4/kamailio' 2. I do "make install-initd-debian" Then make fails with the following error " root@kamServ:/usr/local/src/kamailio-5.4/kamailio# make install-initd-debian make -C src/ install-initd-debian make[1]: Entering directory '/usr/local/src/kamailio-5.4/kamailio/src' sed -e "s#DAEMON=/usr/sbin/kamailio#DAEMON=/usr/local/sbin/kamailio#g" \ -e "s#NAME=kamailio#NAME=kamailio#g" \ -e "s#DESC=Kamailio#DESC=kamailio#g" \ -e "s#HOMEDIR=/run/kamailio#HOMEDIR=/run/kamailio#g" \ -e "s#DEFAULTS=/etc/default/kamailio#DEFAULTS=/etc/default/kamailio#g" \ -e "s#CFGFILE=/etc/kamailio/kamailio.cfg#CFGFILE=/usr/local/etc/kamailio/kamailio.cfg#g" \ < pkg/kamailio/deb/debian/kamailio.init \ > /etc/init.d/kamailio /bin/sh: 1: cannot open pkg/kamailio/deb/debian/kamailio.init: No such file make[1]: *** [Makefile:982: install-initd-debian] Error 2 make[1]: Leaving directory '/usr/local/src/kamailio-5.4/kamailio/src' make: *** [Makefile:34: install-initd-debian] Error 2 " Am I doing something wrong? Possibly in the wrong directory? If you need any more information please don't hesitate to ask. Sincerely, Matthew Sherwood

[kamailio 5.4.3] xavp_rm_by_index removes (N+1) first indexes instead of index N
by Chaigneau, Nicolas 20 Jan '21

20 Jan '21

Hello I’m trying to use function xavp_rm_by_index to remove a specific index from a given xavp. I’m observing an unexpected behaviour, I think it might be a bug : Instead of just removing the index, the function removes the index and all others before it. E.g : if called with « idx = 1 », it removes indexes 0 and 1. Reading the code of xavp_rm_internal (which is called by xavp_rm_by_index), I don’t think it behaves at it should : /* Remove xavps * idx: <0 remove all xavps with the same name * >=0 remove only the specified index xavp * Returns number of xavps that were deleted */ For example when I do this : LM_ERR("COUNT BEFORE: %d\n", xavp_count(rname, NULL)); int rm_count = xavp_rm_by_index(rname, 1, NULL); // TEST LM_ERR("REMOVED: %d\n", rm_count); LM_ERR("COUNT AFTER: %d\n", xavp_count(rname, NULL)); « rm_count » returned is 1 (which is expected). However, « count after » is decremented by 2. And when I look at the contents of my xavp, I notice that the first two elements have been removed. Likewise if xavp_rm_by_index is invoked with idx = 2 => the first 3 elements are removed. So… do you think this is a bug ? or something I didn’t understand ? Thanks for your help ! Regards, Nicolas.

Dialog Tracking with Inconsistent RR
by Charles Phillips 20 Jan '21

20 Jan '21

I am working to track concurrent channels with the dialog module, but I have run in to an issue. Due to the nature of my required configuration, I have a need to strip the record route headers from packets that are sent to the upstream proxy. This leaves no way for the dialog module to track the state of the call. I was hoping that DID_FALLBACK or DID_NONE modes would track by call id or some other constant, but it does not appear to. So, before I start down the path of using htable to store and reinsert the did when a packet returns, is there something I am missing with dialog? Is there some more efficient way to do this? - Charles

Header Manipulation with returned REST data
by Mark Lawrence 19 Jan '21

19 Jan '21

Hi All, Sorry for the intrusion and asking directly, but there’s so much information out there that I would spend years looking for the answer myself and spending equal amount of time in a lab playing. I do like the last idea but time is a little short. I’m thinking of using Kamailio to overcome a few downfalls in the main SBC/PBX commercial product space that I’ve typically deployed and wanted to ask if it is possible to use as a stateful proxy and carry out the following header manipulation type scenario with a bit more dynamassium: Use the FROM and TO header to create two value pairs that would be sent via a REST request to an external application, which will return two corresponding values to (a) supply a different value to update the original FROM header and (b) a full PAI sting to add on to the outgoing message. If you have experience of this or if it’s a nonstarter I’d love to know. There’s so many modules and great stuff that you have in your toy chest it is amazing and kudos to all you developers being so inventive out there: it leaves me to think I’ve been deploying SIP wrong all these years. Thanks and keep safe and well, Mark

Count the rows in a xavp from script
by Chaigneau, Nicolas 19 Jan '21

19 Jan '21

Hello, I'm looking for a way to retrieve the number of rows stored in a xavp. (Something better than manually iterating over the xavp) Basically, I'd like to call xavp_count from the script. Is that possible ? Regards, Nicolas. This message contains information that may be privileged or confidential and is the property of the Capgemini Group.

Kamailio High Availability questions
by Andriano 17 Jan '21

17 Jan '21

Hello have some questions about Kamailio HA + loadbalancers (dispatcher modules) 1. is posible to make HA for RTP media? maybe RTPEngine +redis? is not possible to do this with RTProxy? where is some examples? 2. What do Kamailio db cluster module? it can replicate every DB query record like normal DB cluster? or better is to use native MySQL cluster mode? 3. How is working dispatcher modules in HA? how call is handled and htable in memory between loadbalancers endpoint nodes etc... IS it posible to do only with DMQ ? Just need understand how to do basic Kamailio setup with HA and load balancers in general, for example if will be 2 phisical servers, in every server is virtualisation and every server has 2 VPS. 1 VPS for frontend Kamailio loadbanancer, 1 VPS backend Kamailio app with accounts, routing logic, LCR, RTP media app etc... between load balancers i know maybe is possible to do floating ip, dns round robinetc... and if one VPs server down, call will be dropet in every situation? or call will not be droped and how to prevent it. Just need to know in general schema and architecture how to do this real HA in Kamailio and avoind sinlge point of failure and where to read and learn it ho to make HA in real. In the internet no many docs about it, many conference video how good it is, but no good examples with config, i did not founded, so will be very glad for any help in these newbie questions ;) with single kamailio is many answers, but is realy difficult to understand how to do voip HA with Kamailio without single point of failure. Thanks for any answers...

http_client module not found
by Joli Martinez 15 Jan '21

15 Jan '21

Hello, I am running kamailio 5.3.8 on Debian 9. Kamailio is installed via apt package manager. I am trying to get apiban.org to work and it seems to be having a problem with the http_client module. I have searched for the kamailio modules and I am unable to find anything that resembles http. I have also installed the extra module and no luck. What would be the correct module to install? kamailio: ERROR: <core> [core/sr_module.c:500]: load_module(): could not find module <http_client> in </usr/lib/x86_64-linux-gnu/kamailio/modules/>

Stubs for KEMI Javascript
by Nicki Otte 15 Jan '21

15 Jan '21

Hi everyone. I wanted all of you to know, that I have made JavaScript stubs, for autocompletion in IDE’s, for those of you that use KEMI JavaScript. Specifically tested on Jetbrains PHPStorm/Webstorm. The stubs are available for free at my GitHub page. The link is https://github.com/captainDuckay/Kamailio-javascript-stubs My main language isn't typescript or JavaScript, and this is one of my first public releases. With that said though, I am open for critics, or even guidance. I hope it's usable for you. // Nicki Bo Otte
