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.
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?

Subject: [SR-Users] Add Reason Header to
kamailio generated CANCEL
Hi everyone,
I've got a specific case: when the inv_fr
times out, I
need to add a Reason header to the
CANCEL generated by kamailio. 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.
Is there any way to do it? Or maybe to have
any pointer about
where to look in the code so I
may try to trigger event_route[tm:local-request]
for these generated CANCELs?
Regards,
Alfonso
