Hello!
Call flow: FreeSWITCH --> SBC --> Edge Proxy
In my case, the problem is related to the fact that the SBC deletes the Reason header from FreeSWITCH and I am trying to recover it on the Kamailio side (Edge Proxy).
It is especially important to recover the message: "Call completed elsewhere" because this disables the missed call notification on the destination phone in case of hunt-groups.
The option to forward the call through the stateless loop works well but it complicates the logic unnecessarily.
So would be great to have a tm function to setup custom Reason, like below:...t_cancel_reason("Reason: SIP ;cause=200 ;text=\"Call completed elsewhere\"\r\n");
t_relay();....
iirc, the Reason header should be propagated if it is in incoming CANCEL, so for this particular case, it should work if you do:
if(is_method("CANCEL")) {
append_hf("Reason: ...\r\n");
msg_apply_changes();
t_realy();
exit;
}
Cheers,
Daniel

How do you expect to fill the value of the header?

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.

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?
