The source tree includes an example of how to do this:

https://github.com/kamailio/kamailio/blob/master/examples/vm_proxy.cfg

After fr_inv_timer expires, Kamailio will generate a 408 and call your failure_route, which is where you can redirect to your voicemail server.

I would like to send a call to voicemail server after simple timeout.

Called client replies with prov response (183 with SDP) but doesn't answer, so no 200OK message.

Is it possible to route call to voicemail server? How?

Many thanks
