This is all you should need to setup DUNDi between two boxes with IAX.
You can add more boxes to your network in a similar way.
See also: DUNDi Enterprise Configuration SIP
(Based on configurations in the configs directory from the Asterisk source code and documents published by Brian K. West aka bkw_)
On both boxes in your extensions.conf:
; the first three contexts are separated in order to group them by the appropriate dundi priority
; Private DUNDi network
[dundi-priv-canonical]
; Direct numbers (dundi priority 0)
[dundi-priv-customers]
; If you are an ITSP or Reseller, list your customers here. (dundi priority 100)
[dundi-priv-via-pstn]
; If you are freely delivering calls to the PSTN, list them here (dundi priority 400)
; this context is used to group the 3 above and reference in iax.conf for the incoming calls referred by dundi
[dundi-priv-local]
include => dundi-priv-canonical
include => dundi-priv-customers
include => dundi-priv-via-pstn
; the rest of the contexts are used for calls placed locally to go out to our dundi peers
; entry point is macro-dundi-priv
[dundi-priv-switch]
; Just a wrapper for the switch
switch => DUNDi/priv
[dundi-priv-lookup]
include => dundi-priv-local
include => dundi-priv-switch
[macro-dundi-priv]
exten => s,1,Goto(${ARG1},1)
include => dundi-priv-lookup
iax.conf on both boxes:
[priv]
type=user
dbsecret=dundi/secret
context=dundi-priv-local
In this example, “dundi/secret” should be taken literally. It refers to the family/key in astdb that pbx_dundi.so stores a password that is changed every hour. It’s also what pbx_dundi.so substitutes in place of ${SECRET} below when replying to queries.
dundi.conf on both boxes under [mappings]:
In many cases you will need to replace ${IPADDR} with your local IP address
priv => dundi-priv-canonical,0,IAX,priv:${SECRET}@${IPADDR}/${NUMBER},nopartial
priv => dundi-priv-customers,100,IAX,priv:${SECRET}@${IPADDR}/${NUMBER},nopartial
priv => dundi-priv-via-pstn,400,IAX,priv:${SECRET}@${IPADDR}/${NUMBER},nopartial
now on each box cd /var/lib/asterisk/keys
astgenkey -n [BOXNAMEHERE]Press enter do not put a password on the keys unless you want to init keys every time you start asterisk.
Now exchange public keys between the boxes.
Box A dundi.conf:
[DE:AD:BE:EF:DE:AD] <-- EID/MAC from BOX B
model = symmetric
host = boxb.domain.com
inkey = BOXB <- BOX B's public key
outkey = BOXA <- BOX A's private key
include = priv
permit = priv
qualify = yes
order = primary
Box B dundi.conf:
[BE:EF:DE:AD:BE:EF] <-- EID/MAC from BOX A
model = symmetric
host = boxa.domain.com
inkey = BOXA <- BOX A's public key
outkey = BOXB <- BOX B's private key
include = priv
permit = priv
qualify = yes
order = primary
Now you can do this in the context which your devices dialout:
exten => _91NXXNXXXXXX,1,Macro(dundi-priv,${EXTEN:1})
exten => _91NXXNXXXXXX,2,Dial(Zap/g1/${EXTEN:1}) ; This is fall through example to a PSTN such a as PRI
And find numbers in your enterprise DUNDi network.
These same things apply to the e164 DUNDi network too.
