How to modify INVITE Request Line string
by Jose Figueroa 09 Nov '20

09 Nov '20

Hello everybody, Today I received a request from a carrier which needs us to send the calls using a prefix in the INVITE header. I am reading the documentation for kamailio 4.3.x but I havent found anything I can use in order to modify the Request Line (INVITE) string. I need to change from this: INVITE sip:123456789@IP:5060 to this: INVITE sip:PREFIX123456789@IP:5060 If you can guide me to the right direction would be more than great. Thanks -- Jose Figueroa Senior Software Engineer

Hi, How to do git clone of kamailio source code with minor version. I could only do git checkout of 5.3 version and it is automatically taking latest stable version. I don't need in this way. I need to do git clone of exact version of kamailio source code . Example - if I need 5.3.6 version.. exact version source code has to be git checked out from kamailio website. How to do that .. kindly let me know.. Thanks, Pavithra

Re: [SR-Users] Proxy configuration that exit dialog afer INVITE -> OK
by Yufei Tao 07 Nov '20

07 Nov '20

Hi, Here's an example kamailio.cfg that uses record_route so in-dialog requests will go through the Kamailio proxy: https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg There are many other example cfg files: https://github.com/kamailio/kamailio/tree/master/misc/examples Any server that wants to see the in-dialog messages needs to add itself to the record route list when receiving the initial INVITE for example. If a server is not in the list of record routes, then in-dialog requests will not be sent to the server. Headers that are most important in terms of routing are R-URI, Route, Record-Route, Contact, Via. Via header is for routing responses, while Record-Route is for in-dialog requests. I've put a few tips and some resources here about starting with Kamailio, which hopefully may help you a bit: http://tao-communications-ltd.simplesite.com/447576389 Cheers, Yufei >* Message: 7 *>* Date: Thu, 5 Nov 2020 12:26:16 +0200 *>* From: "Adrian Tabacioiu" <Adi.Tabacioiu at c-s.ro <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users>> *>* To: sr-users at lists.kamailio.org <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users> *>* Subject: [SR-Users] Proxy configuration that exit dialog afer INVITE *>* -> OK *>* Message-ID: <7449102a9f3dbe38b6dba753d1cffcd8.squirrel at mail.c-s.ro <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users>> *>* Content-Type: text/plain;charset=iso-8859-1 *>>>* Hello all, *>>* Am I new in the usage of kamailio, sorry if I ask somehow something simple *>* or terribly wrong . *>>* I need to test a configuration of Kamailio which exit the dialog between *>* UA after the first OK (that means it will not receive the following ACK, *>* BYE). *>>* I understand that in theory this is possible in two configuration types: *>* - no Record Route header *>* - or stateless proxy *>>* First question: *>* Am I correct with the choices above? *>* Can I find example configuration for this two modes ? *>>* Question 2: *>* two or more proxy should be inter-connected, removing the Record Route *>* header would interfere with proxy routing ?

Kamailio dump configuration and exit?
by Brandon Armstead 07 Nov '20

07 Nov '20

Is there a similar hook to make kamailio dump its current configuration it is reading including ... included files, i.e. similar to nginx -T root@main:/home/brandon# nginx -h nginx version: nginx/1.14.2 Usage: nginx [-?hvVtTq] [-s signal] [-c filename] [-p prefix] [-g directives] Options: -?,-h : this help -v : show version and exit -V : show version and configure options then exit -t : test configuration and exit -T : test configuration, dump it and exit -q : suppress non-error messages during configuration testing -s signal : send signal to a master process: stop, quit, reopen, reload -p prefix : set prefix path (default: /usr/share/nginx/) -c filename : set configuration file (default: /etc/nginx/nginx.conf) -g directives : set global directives out of configuration file Thanks for your time in advance!

send_reply() related feature request
by Juha Heinanen 06 Nov '20

06 Nov '20

Many times (especially when there is a hacking attempt) I want to close TCP or TLS session after sending reply. So, for example, I write: set_reply_close(); send_reply("403", "Forbidden"); It would be more convenient if these two calls could be combined into one, for example: send_reply_and_close("403", "Forbidden"); -- Juha

tsilo - failure to add branches (-1)
by Jurijs Ivolga 05 Nov '20

05 Nov '20

Hi, I have several Kamailio proxies - loadbalancer which is used as TLS offload and Authorization server and behind registrar servers. In this case I can't make tsilo work on the registrar server. I'm always getting: "tm [t_append_branches.c:172]: t_append_branches(): failure to add branches (-1)" If I use just one Kamailio which is used as Authorization and Registrar server then tsilo works as expected. Looks like kamailio where I run ts_append tries to connect to UAC directly and not through Loadbalancer. Any ideas? How can I troubleshoot this? Thank you! Jurijs

Proxy configuration that exit dialog afer INVITE -> OK
by Adrian Tabacioiu 05 Nov '20

05 Nov '20

Hello all, Am I new in the usage of kamailio, sorry if I ask somehow something simple or terribly wrong . I need to test a configuration of Kamailio which exit the dialog between UA after the first OK (that means it will not receive the following ACK, BYE). I understand that in theory this is possible in two configuration types: - no Record Route header - or stateless proxy First question: Am I correct with the choices above? Can I find example configuration for this two modes ? Question 2: two or more proxy should be inter-connected, removing the Record Route header would interfere with proxy routing ? (should not the "Via" information be sufficient?) Thank you in advance for help. Best regards, Adrian Tabacioiu
