Maybe cnxcc module can help you [1].

If you need to set a time limit you could use cnxcc_set_max_time() and when the call times out, an event route is called.

Hi Daniel,
thank you for your answer.
I tried to catch the BYE with event_route[dialog:end] but I'm facing another problem.
When the timeout for the dialog is reached Kamailio correctly sends a BYE to the caller and to the callee but in the logs I see this:

The parser error problem seems to be related to the To and From headers of FAKED_SIP_MSG, defined in lib/kcore/faked_msg.c. 
If I change those URIs adding "sip: " the pv error disappears but once entered the event_route[dialog:end] 

INFO: <script>: event_route[dialog:end]: call-id=123 from=you to=you : (method= OPTIONS) :: dlg flag: 18446744073709551615 :: DLG_lifetime: <null>
WARNING: dialog [dlg_req_within.c:177]: inconsitent dlg timer data on dlg 0x7fa07e0c6fe0 [2950:12062] with clid '1518225741' and tags '717826890' '1348505040'

As you can see,  the $DLG_lifetime is <null> and we also have the message on the inconsistent dlg timer.

Probably there is something that I'm not understanding but why the event_route in this case is processing a "fake" OPTIONS message?
Another thing I noticed is that event_route[dialog:end] is not executed when a dialog is terminated by dlg_end_dlg or dlg_terminate_dlg fifo commands.
We really need to access the DLG_lifetime value in both cases (internal timeout or external command), any hint on how to do it?

Thank you in advance.

Regards,

Federico

Hello,

there is an event route for dialog timeout, I guess there is available. tm:local is executed by tm, so you may need to call the function that lookups the dialog.

Cheers,
Daniel

Hello ,


Is the $DLG_lifetime supposed to be accessed in the event_route[tm:local-request] ?

We are trying to access it and it always reports null with kamailio 4.0.0 .

We found a reference about this here: 

.....
  dialog(k): run event route after setting cfg dlg vars
    
    - in this way they (e.g., $DLG_lifetime) should be accessible in event
      route
    (cherry picked from commit 2cdded28d9968a0b78f5ec8329ae6983d9ea77a9)
.....

Apparently it should have been possible.
Any hints on this ?

Thank you!

Regards,
Dragos & Federico
