[Asterisk-Users] RE: DUNDi .... Halfway and CLUSTERING

[Watkins, Bradley]

At the moment I'm out of the office, but when I return I'll be certain to do
that.  Note that my solution is different from what you are working on with
regexten, though I suspect some of the challenges that I've faced and
overcome are not.  I'm actually using UltraMonkey for load-balancing and
failover of the Asterisk boxes, and my dialplan is set up so that it need
not be changed when extensions are added or removed.  I've been meaning for
some time to do a write-up of how it all works, both in the hopes of giving
my knowledge back to the community as well as learning some things that may
help me improve the solution.

I've had to make a couple of (minor) tweaks to both app_voicemail.c (to
ensure proper password synchronization) and pbx_dundi.c.  The latter is for
larger sites(more than one cluster since my clusters are designed as
"buliding blocks" of two Asterisk systems), adding a count flag to return
the number of matching records and the ability to return a specific record.
The former, I suspect, would be unnecessary if I were using Realtime for
voicemail.  But I'm not using Realtime for anything at the moment.

Anyway, I apologize for not being able to answer you fully right now, but
I've got this set to remind me to follow up on Monday.

Regards,
- Brad

Doug,

I feel your pain.  I have, since 3 days ago, all but giving up on dundi in a
enterprise/carrier core scalable environment, mostly due to no ability to
summarize dial plan routes across several servers that may or may not have
contiguous extensions registered across the cluster.

Example server 1 has exten 1234, 1235, 1001, 1002 registered and server 2
has 1236, 1237, 1003, 1004. But also in a failure or load balancing event,
server 1 could have 1236, 1001, 1235, 1004 and server 2 could have 1237,
1234, 1002 and 1003 registered.

The dynamic nature on maintaining extension state across many registration
servers in real time, is not something dundi, realtime or
regcontext/regexten can handle right now.  At least I haven't figured it out
yet.

Brad,

Please be so kind to publish your dundi.conf configs and also dundi snips
from extension.conf for server 1, server 2, server3......

Thanks Guys.

JR

Could you perhaps post your dundi.conf for both boxes?  I'm afraid this
message doesn't mean anything to me, but I have about a dozen boxes doing
DUNDi peering so I know what the config should look like.  But it's
basically always worked for me.

Regards,
