Hi JR. I'm dying to know... where'd you find your DUNDi documentation? Has something new appeared since I looked at it 2-3 months ago? The O'Reilly book's DUNDi section was impossible to follow, and the examples in the Asterisk DUNDi config files are no better. You do a search online and get almost no results (still wondering when Digium is going to realease some docs for what they call their protocol). I spent a few weeks working on it, tearing my hair out, and gave up. So did my boss.

Hello All,
Ive been doing more and more research on trying to setup a cluster/load
balancer for Asterisk. All the Asterisk boxes would be using a config that
is the same between them all (via a DB), but we want one location to point
the phones to, and from there that machine/device will send it to a Asterisk
server so the call can be processed. I know you cant balance the whole call,
ie: once the call is started the RTP stream has to go to the same server,
but a new call could go to a different server if perhaps the 1st server was
unreachable.
Has anyone tried this, or got this to work? Ive been looking at using a
Juniper Session Border Controller, but not sure if thats gonna do the trick,
and then we also have SER..
Any comments would be great!
Thanks
Ron

Ron,
I'm doing something similar with clustering. I haven't gotten the total design down yet but so far I have 1 * server holding all the routes to several child/registration * servers where my iax and sip clients actually register to. I'm using the 1 * server running dundi to peer with all the registration servers and all the registration servers only peer with the 1 * server, I call this the Registration Presence Server or RPS. When a child/registration server does a lookup request to the RPS, the RPS does a lookup on all the other registration servers and knows who is registered where and relays that info back to the original requesting registration server. Use a dundi ttl=1 in the RPS and ttl=2 in each registration server to avoid routing loops. I'm still in the testing phase but it's going well, but I'm running into some cache timeout issues when a client drops off and re-registers to a different registration server, have to flush dundi to pickup the new location. There is a cache timeout parameter I have yet to play with.
I don't have the load balancing session border controller function down yet, but that is on the list of things to do.
Hope this helps.
