Hi All
We wan't to prevent our users to make more than one call at time, so we choose to disconnect the previous call. When the previous call is established, we use dlg_bye(), and its ok. But when it is in early state, we use t_cancel_callid() to cancel its INVITE transaction.
We face 2 issues: 1) we use local-request event route to account calls on timeout. Sometimes this route is called for the cancelled call (after default timeout of 1 hour)
what is in the local-request in this case? Is it a BYE?
- t_cancel_callid() cancel previous call, but also _make current
dialog disappear_: call is still ongoing and we can answer and talk to each other, but the dialog does not appear in 'kamctl stats dialog' and 'kamctl mi dlg_list' commands
Is there a known limitation, or do we misuse t_cancel_callid() ?
Can you send the log with debug=3 in kamailio.cfg? It will help to see what happens. Otherwise, if the call id is different for current dialog, it should not happen. The ngrep output in this situation (for both first and second invite) will help.
Cheers, Daniel
Hi Daniel,
local-request is triggered by a BYE I have attached sample log and trace
There is some kind of dialogs mixing. Here is the 1st call dialog as reported by "kamctl mi dlg_list" _before and after_ the 2d call is answered:
