We are in a project right now where we have build a single asterisk
switch acting as a master SIP router and delivering service to and
from about 30 xen-based VMs. It is a multi-tenant build. I am not
certain if this is your particular scenario or if I am off-base.
A word of caution, though. Do not run SIP routing functions on Dom0
in a Xen environment and do not use Asterisk 1.4 for these functions
yet. In testing, we encountered routine segmentation faults on both
our Dom0 and our 30 DomUs. We fixed this issue by separating the
core SIP routing functions to a stand-alone server and by downgrading
all DomUs to Asterisk 1.2.14.
Our entire architecture is Fedora 6, by the way. DomU is 32bit and
all DomUs are run on a single, large 64bit server platform.
I hope this is helpful.

Hi Bryan,
I was trying to avoid creating an architecture dedicated to VM, but
have Asterisk handle VM in a horizontally scalable way. I
understand there are some issues with MWI etc. if you separate out
the VM from Asterisk? Could you point me at any good examples of a
VM architecture I could use as a reference?
Cheers,
Ray

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
