<DIV><FONT face=Arial size=2>Chris,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Heartbeat failover will usually be your best
mixed approach.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>As always there is a cost benefit to be
considered.</FONT></DIV>
<DIV><FONT face=Arial size=2>Where the call absolutely has to stay up then
Fault-Tolerant software and hardware is the only option that works with
Asterisk to date.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If however you wish to keep costs to a mimimum
then possibly an onsite / hosted model where the back up is available
remotely. This model depends on set up however.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In all cases I would suggest you take a peruse of
PBXware : <A

is our SMB Edition. We will next week launch our Call Center Edition that is

carrier grade redundant solution</DIV>
<DIV><BR></DIV>Hello List -<BR><BR>We are looking add Asterisk to the core
of our voice/data network. Our first application will provide a hosted
call center application for a number of tenants (customers) who will have
between 5-20 agents (seats) answering ingress calls. The calls will
ingress and egress the Asterisk server SIP (all TDM is handled by Sonus
switches). <BR><BR>My goal is to design a redundant solution using a
multiple Asterisk servers with an NFS mounted filesystem.<BR><BR>I've done
some reading regarding Asterisk redundany, and so far it seems the best
approach is running redundant hardware (power supplies etc), matching
servers (with a heart beat ping between them) and a NFS filer for storage
(hot swapable) connected to each box via gigE. <BR><BR>Am I on the right
track? Any other suggestions or resources I might have missed
regarding developing a redundant solution?<BR><BR>Thanks for your
time,<BR><BR>_Chris_<BR>
