[asterisk-users] 1.8.1: playing imaginary sound files

[sean darcy]

............
     -- Executing [s at incoming-pstn-line:5] VoiceMail("DAHDI/4-1", 
"100 at default,u") in new stack
     -- <DAHDI/4-1> Playing 
'/var/spool/asterisk/voicemail/default/100/unavail.gsm' (language 'en')
..........

But there is no /var/spool/asterisk/voicemail/default/100/unavail.gsm', 
indeed no unavail.gsm on the machine.

[asterisk at asterisk ~]$ find /var/spool/asterisk -name unavail.gsm
[asterisk at asterisk ~]$

There is a wav file:

[asterisk at asterisk ~]$ ls /var/spool/asterisk/voicemail/default/100/
INBOX  Old  tmp  unavail.WAV  Urgent

puzzled.
