There are several options here, unfortunately none really simple. Here
is one:
a) after creating the dialog (at initial INVITE time), save the Call-id
into a $dlg_val [1]
$dlg_val(my_callid) = $ci;
b) in event route, use load_dialog_ctx() [2] - do NOT forget to pair it
with the unload function
load_dialog_ctx("$param(id)", "did");
$var(callid) = $dlg_val(my_callid);
load_dialog_ctx();
....
# you have the callid into $var(callid) for further processing

[2]
https://opensips.org/html/docs/modules/3.2.x/dialog.html#func_load_dialog_ctx
Another option may be the usage of local cache to store the SIP callid
under the dialog ID as key, at INVITE time:
https://opensips.org/html/docs/modules/3.2.x/dialog.html#pv_DLG_did
https://www.opensips.org/Documentation/Script-CoreFunctions-3-2#cache_store
And in event route simply use the cache_fetch() with the dialog ID as
key also.

Is there way to obtain the SIP Call ID from the "id" or when is_callid=0?
if I save the callID on a global variable, will it be visible
around all the code?
Sorry I am still learning the ropes.

Hi,
As per docs [1], you have in event_route :
id - represents the identifier of the call for which that event
was received.
is_callid - is 0 if the id parameter represents the Dialog ID, or
1 if it is a callid.

My goal is to close the call as soon as the callee presses
any DTMF
when any DTMF is detected, then I need to access the callID
variable, $ci
but it's nowhere to be found
Also I need $avp(start_time) and $avp(duration)
I am at a loss as to how to retrieve this information. The call
is connected
I need to fire a database query to close the call.
I imagine that when the call got connected, some variable stored
that unix-time .
But it does not seem to be available in this part of the code.
