-+; should someone else in your peer group need to contact you.
-+;
-+;department=Your Department

-+;locality=Your City

-+;
-+;bindaddr=0.0.0.0
-+;port=4520
-+;
-+; Our entity identifier (Should generally be the MAC address of the
-+; machine it's running on. Defaults to the first eth address, but you
-+; can override it here, as long as you set it to the MAC of *something*
-+; you own!)
-+;
-+;entityid=00:07:E9:3B:76:60

-+; Define the max depth in which to search the DUNDi system (also max # of
-+; seconds to wait for a reply)
-+;
-+ttl=32
-+;
-+; If we don't get ACK to our DPREQUEST within 2000ms, and autokill is set
-+; to yes, then we cancel the whole thing (that's enough time for one
-+; retransmission only). This is used to keep things from stalling for a long
-+; time for a host that is not available, but would be ill advised for bad
-+; connections. In addition to 'yes' or 'no' you can also specify a number
-+; of milliseconds. See 'qualify' for individual peers to turn on for just
-+; a specific peer.
-+;
-+autokill=yes
-+;
-+; pbx_dundi creates a rotating key called "secret", under the family
-+; 'secretpath'. The default family is dundi (resulting in
-+; the key being held at dundi/secret).
-+;
-+;secretpath=dundi
-+;
-+; The 'storehistory' option (also changeable at runtime with
-+; 'dundi store history' and 'dundi no store history') will
-+; cause the DUNDi engine to keep track of the last several
-+; queries and the amount of time each query took to execute
-+; for the purpose of tracking slow nodes. This option is
-+; off by default due to performance impacts.
-+;
-+;storehistory=yes
-+
-+[mappings]
-+;
-+; The "mappings" section maps DUNDi contexts
-+; to contexts on the local asterisk system. Remember
-+; that numbers that are made available under the e164
-+; DUNDi context are regulated by the DUNDi General Peering
-+; Agreement (GPA) if you are a member of the DUNDi E.164
-+; Peering System.
-+;
-+; dundi_context => local_context,weight,tech,dest[,options]]
-+;
-+; dundi_context is the name of the context being requested
-+; within the DUNDi request
-+;
-+; local_context is the name of the context on the local system
-+; in which numbers can be looked up for which responses shall be given.
-+;
-+; tech is the technology to use (IAX, SIP, H323)
-+;
-+; dest is the destination to supply for reaching that number. The
-+; following variables can be used in the destination string and will
-+; be automatically substituted:
-+; ${NUMBER}: The number being requested
-+; ${IPADDR}: The IP address to connect to
-+; ${SECRET}: The current rotating secret key to be used
-+;
-+; Further options may include:
-+;
-+; nounsolicited: No unsolicited calls of any type permitted via this

-+; nocomunsolicit: No commercial unsolicited calls permitted via
-+; this route
-+; residential: This number is known to be a residence
-+; commercial: This number is known to be a business
-+; mobile: This number is known to be a mobile phone
-+; nocomunsolicit: No commercial unsolicited calls permitted via

-+; to any request, although it may be empty.

-+; that we fundamentally trust. The section name
-+; represents the name and optionally at a specific
-+; DUNDi context if you want the trust to be established
-+; for only a specific DUNDi context.
-+;
-+; inkey - What key they will be authenticating to us with
-+;
-+; outkey - What key we use to authenticate to them
-+;
-+; host - What their host is
-+;
-+; order - What search order to use. May be 'primary', 'secondary',
-+; 'tertiary' or 'quartiary'. In large systems, it is beneficial
-+; to only query one up-stream host in order to maximize caching
-+; value. Adding one with primary and one with secondary gives you
-+; redundancy without sacraficing performance.
-+;
-+; 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.
-+;
-+; noinclude - Disincludes this peer when searching a particular context
-+; for lookup (set "all" to perform no lookups with that
-+; host.
-+;
-+; 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.
-+;
-+; deny - Denies this peer to search a given DUNDi context on
-+; the local system. Set "all" to deny this host to
-+; lookup all contexts.
-+;
-+; 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.
