Description: When setting up the dundi pre-cache in an inbound / outbound model->

PEER-A <----Pre Cache--------< PEER B

PEER-A <-----Lookups---------< PEER B

I see a noauth error referring to the context, which from my configs I'll include you'll see is clearly not the case.

****** ADDITIONAL INFORMATION ******

Config on PEER A:
;PEERB
[00:00:00:00:00:0B]
model = outbound
precache = outbound
host = #.#.#.#
inkey = voip-internal
outkey = (OMIT)
register = yes

Additionally I get the same problem when both PEERS use "all" for the permit and include options.

Assigning this issue to myself as I will attempt to confirm the issue.

Aha!

This is a configuration issue. And the nuances are subtle because I got caught by it too.

You need to read these two sections a bit more carefully (as I did too!) from dundi.conf:

; include - Includes this peer when searching a particular context
; for lookup (set "all" to perform all lookups with that
; host. This is also the context in which peers are permitted
; to precache.

; permit - Permits this peer to search a given DUNDi context on
; the local system. Set "all" to permit this host to
; lookup all contexts. This is also a context for which
; we will create/forward PRECACHE commands.

; model - inbound, outbound, or symmetric for whether we receive
; requests only, transmit requests only, or do both.
;

; precache - Utilize/Permit precaching with this peer (to pre
; cache means to provide an answer when no request
; was made and is used so that machines with few
; routes can push those routes up a to a higher level).
; outgoing means we send precache routes to this peer,
; incoming means we permit this peer to send us
; precache routes. symmetric means we do both.
;
; Note: You cannot mix symmetric/outbound model with symmetric/inbound
; precache, nor can you mix symmetric/inbound model with symmetric/outbound
; precache.

Here is a working configuration for pre-caching in one direction. I will leave it as an exercise for the original reporter to get it working bi-directionally (I think you just need to change the model and precache to symmetric and configure out permits and includes appropriately):

(NOTE: as writing this, I learned that permit is what you SEND via precache, and include is what you RECEIVE via precache.)

; This peer will receive pre-caching from the other peer
[00:00:00:00:00:02]
model = inbound
precache = inbound
host = 192.168.128.52
inkey = ClusterTestTwo
outkey = ClusterTestOne
include = private-pstn
qualify = yes

; This peer will sent pre-caching to the other peer
[00:00:00:00:00:01]
model = outbound
precache = outbound
host = 192.168.128.51
inkey = ClusterTestOne
outkey = ClusterTestTwo
permit = private-pstn
qualify = yes

On this same server that is sending the pre-cache, I configured this mapping:

private-pstn => private-pstn,0,SIP,remote_server/${NUMBER},nopartial

Then in the dialplan (extensions.conf), I setup these numbers for precaching:

[private-pstn]
exten => 5195915119,1,NoOp()
exten => 4166289921,1,NoOp()

Then when I had both servers up and running, and reloaded the DUNDi module (pbx_dundi.so), I get this in my database on the other server:

*CLI> database show
/dundi/cache/000000000002/4166289921/private-pstn/e00000000: 1228994035|1/0/2/remote_server/4166289921/000000000002|
/dundi/cache/000000000002/4166289921/private-pstn/r000000000000: 1228994035|1/0/2/remote_server/4166289921/000000000002|
/dundi/cache/000000000002/5195915119/private-pstn/e00000000: 1228994035|1/0/2/remote_server/5195915119/000000000002|
/dundi/cache/000000000002/5195915119/private-pstn/r000000000000: 1228994035|1/0/2/remote_server/5195915119/000000000002|

This shows the precaching being done successfully.

You can verify this with 'dundi debug' on the CLI (or dundi set debug {on|off} in Asterisk trunk and Asterisk 1.6.2 and beyond):

Closing issue as this was a configuration issue.
