In the ser admin guide it says

"You can refer to voicemail example config file to know what your configuration file should include. Note that voicemail uses subsriber database table to determine recepient's email address. Read the README file in the vm module directory for complete description of the functions and variables that are used by voicemail and how they work."

I can't find any complete descriptions of the functions and variables and how they work. The README file is very short and basic.

In the example config file there are many calls to vm(/tmp/am_fifo", "*"); where * is "announcement" or "voicemail" or "echo" or "bye" or "conference." Are these all required in a basic voicemail setup? C

If you want to setup voicemail, use just vm("/tmp/am_fifo", "voicemail"); the second parameter describes behaviour of the media component. You don't want to deploy the other examples.

an anyone point me to more information on how this works and what each of these modules are doing?

If I call a user who isn't logged in I can hear the voicemail default greeting, but then the line goes silent. I don't think there is any voice recording happening. See ser.cfg attached.

Recorder is silent when it records, that's normal behaviour. What matters is whether you then receive a WAV file by email or not. SEMS is running (you hear announcement), so you should.

Also, if a timer is set to send calls to vm (using failure_route) after a certain timeout, is there a way to prevent that timeout from killing calls routed to the PSTN?

If you want failure_route to be evoked only for some calls, then set t_on_failure_route for such. You already do so in your script, don't you?

There is other problem though -- the failure_route logic for VM should be different from that in route block -- you can't create transaction state two times (first time with t_relay, second time with t_newtran). SER will certainly complain with some error message in your logs.

I will introduce some new command which hides details of transaction processing from script writers and can be used from both route[] and failure_route[]. (I didn't think of it before since I used voicemail on some other machine than proxy server.)
