Hi Joe,
I too am using asterisk & dundi on VMs. I use static ip
& hostnames for all of my dundi members so I am curious
as how you keep your dundi.conf files in order.
As far as getting more deterministic/smart routing out of
DUNDi going, you've only got three things you can pick
from:
-The dundi community you're peering with/searching
against (you can make up your own private ones, maybe one
per app) (TX)
-The uri you are looking up/broadcasting (maybe you
should just use the CID number as EXTEN instead of the PSTN
nmber of your application?) (TX)
-The weight you are assigning to your broadcasted URI's
(RX)
There's no built in channel for communicating variables, but
you can try using the three above to approximate it.
You can use special DNIS/CID-depending logic on your master
box at lookup time to select a specific community to search
against using FUNC(DUNDILOOKUP), but the only way to get the
peered members to give a variable dundi reponse is to use
the variable-weight-patch (http://www.aste
riskpbx.com/node/48321 - http://svn.digium.com/view/asterisk?view=rev&
revision=58304 ). Perhaps on all your virtual machine
peers you can assign a SHELL() command that will do an
out-of-channel communication between your master box and vms
to share the DNIS/CID and the vm's SHELL program could then
perform it's own logic and answer by returning the DUNDi
weight for that particular lookup accordingly.
Even when making the weight variable, the best you can do
using either FUNC(DUNDILOOKUP) or switch => dundi is to
pick the unconditional winner. I don't know if this will be
a problem for your application "mesh" or not.
Asterisk 1.6 seems like it will have more ability to browse
through several dundi matches and let your dialplan pick the
winner - I have not tested the preview release yet.
