Re: [SR-Users] Add Reason Header to kamailio generated CANCEL

Hello guys, We have faced almost the same problem adding *Reason: SIP;cause=200;text="Call completed elsewhere"* to the t_relayed CANCEL request. Is there an elegant solution to add this header? PS. Switching to the stateless mode does not look pretty for us...   сб, 1 февр. 2020 г. в 06:04, Alfonso Pinto &lt;alfonso.pinto(a)gmail.com <mailto:alfonso.pinto@gmail.com>>: Hi guys, Thanks for your answers. I did try local_cancel_reason and it’s not doing anything for the CANCELs generated by kamailio. Isn’t that parameter intended for the CANCELs received and then relayed? As Alex and David mentioned, what I need is to add my own reason header. There are some cases that requires to set the Reason header to something specific. IE: terminal supported call waiting in IMS. Thanks for the piece of code, I will check what can be done here.

Just looked briefly, this seems to be the code: t_msgbuilder.c /* Build a local request based on a previous request; main  * customers of this function are local ACK and local CANCEL  */ char *build_local(struct cell *Trans,unsigned int branch,         unsigned int *len, char *method, int method_len, str *to         , struct cancel_reason* reason         ) Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ <https://skalatan.de/blog/> Kamailio services – https://gilawa.com <https://gilawa.com> -----Original Message----- From: sr-users &lt;sr-users-bounces(a)lists.kamailio.org <mailto:sr-users-bounces@lists.kamailio.org>> On Behalf Of Alex Balashov Sent: Friday, January 31, 2020 9:45 PM To: sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org> Subject: Re: [SR-Users] Add Reason Header to kamailio generated CANCEL I understood Alfonso's question to implicitly be: how can I add a dynamic and variable Reason header to outgoing CANCELs? Perhaps I was mistaken. But if I'm not, as far as I know there is no means of doing that. Right?

I've tried to see if I could do it in the onsend_route, but that one is not triggered for the generated CANCEL. I also checked event_route[tm:local-request], but that one isn't triggered either for the generated CANCEL. about where to look in the code so I may try to trigger event_route[tm:local-request] for these generated CANCELs? <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users> -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/ <http://www.evaristesys.com/>, http://www.csrpswitch.com/ <http://www.csrpswitch.com/> _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users> _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users> -- BR, Denys Pozniak _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
