Hello!

We need to append our own Reason header for the "relayed" CANCEL message, if it is not on the input.
Like below:

if ( is_method("CANCEL") && !is_present_hf("Reason") ) {
append_hf("Reason: ....);
t_relay();
...

Hello,

what is exactly the problem? The header is not added if you enable:

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...

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.

Regards,

Alfonso

Hi Alex,

ok, I was reading that he wants to get just one reason header, not one dynamic generated.

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

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.
