Hi,

I've been struggling with this problem very long time and I am starting to be quite desperate.

I'm trying to implement voicemail redirection after 15 secs of ringing. So I set fr_inv_timer, set the event handler with t_on_failure. But after 15secs of ringing the failture_route block does not execute at all, the transaction is lost and after these 15 secs it has strange behaviour (the phone is still ringing, even after the other side has cancelled the call).

I'm attaching the configuration without sensitive data. Please tell me whether problem is in the configuration or somewhere outside of kamailio. Thanks for any suggestion.
