I would like to forward all incoming calls that are not answered from kamailio, to my
asterisk voicemail server. - I have not setup any Realtime Integration.
I am using the "Redirected Dialed Number Information Service" header and calling
"554(a)192.168.1.134" which is my voicemail server.
Forwarding succeeds when the subscriber is not registered to kamailio:
Nov 7 16:19:45 spock /usr/sbin/kamailio[17606]: ERROR: <script>: =============User
sip:6297@192.168.1.131 not found here, going to voicemail=============
Nov 7 16:19:45 spock /usr/sbin/kamailio[17606]: ERROR: <script>: #012 RDNIS =
sip:297@192.168.1.134

=============forwarding to voicemail1, RDNIS: sip:297@192.168.1.134 ===========
I tried to modify the failure route in order to also forward not answered (failed?) calls
to asterisk mailbox but i get the following error and the call is never forwarded:
