RTP Querys
by Ahmed Marsou 22 Jan '21

22 Jan '21

Hi guys; I have some rtpproxy questions: - When a proxy is in a failed state, what happens to the active sessions / streams? - How many times the module should retry to send and receive after timeout was generated? - *How often are the control messages sent to the rtp proxy’s in the pool?* *- I would like to know the exact nc message that’s used for the control messages* *Thank you.*

tracking usrloc clean
by Michal Popovic 22 Jan '21

22 Jan '21

Hi All, I would like to ask you if there is any way how to track usrloc location cleaning operation with some event route, so I can broadcast the change with for example kafka message. If no, how do you keep track of online/offlice status of the user? I am trying to avoid using change data capture in mysql proxy for location table. Michal

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?

[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.
