[asterisk-users] Voicemail personalised greetings using DB/IMAP backend?

[Ray Jackson]

Hi all,

I am attempting to build a horizontally scalable Asterisk deployment and 
am getting very close to achieving that goal.  With Asterisk 1.4 I now 
have an IMAP backend for Voicemail messages which is great as users can 
check the same messages either through the voice portal or using 
Webmail.  However, I'm not sure the best way of dealing with 
personalised greetings such as a user's unavailable/busy message etc. 
Despite the IMAP backend these greetings appear to be stored on the 
local file system under /var/spool/asterisk/voicemail/default, which 
means if I build a farm of Asterisk servers - each will have it's own 
spool directory.  My aim is to have *nothing* stored locally at all...

If there a way of storing these greetings in a database table or using 
IMAP?  I saw the ODBC voicemail storage module, but I would prefer to 
stick with a REALTIME/IMAP backend?  If I mount the 
/var/spool/asterisk/voicemail directory remotely using a shared NFS 
mount on a NAS device will this work okay or lead to problems/race 
conditions etc.?  Any advice would be welcome!

Regards,
Ray
