DUNDi works by creating a +network of nodes called the "DUNDi E.164 Trust Group" which are bound by +a common peering agreement known as the General Peering Agreement or +GPA. The GPA legally binds the members of the Trust Group to provide +good-faith accurate information to the other nodes on the network, and +provides standards by which the community can insure the integrity of +the information on the nodes themselves. Unlike ENUM or similar +systems, DUNDi is explicitly designed to preclude any necessity for a +single centralized system which could be a source of fees, regulation, +etc. + +Much less dramatically, DUNDi can also be used within a private +enterprise to share a dialplan efficiently between multiple nodes, +without incurring a risk of a single point of failure. In this way, +administrators can locally add extensions which become immediately +available to the other nodes in the system. + +For more information visit \url{http://www.dundi.com} + +\section{DUNDIQUERY and DUNDIRESULT} + +The DUNDIQUERY and DUNDIRESULT dialplan functions will let you initiate +a DUNDi query from the dialplan, see how many results there are, and access +each one. Here is some example usage: +\begin{astlisting} +\begin{verbatim} +exten => 1,1,Set(ID=${DUNDIQUERY(1,dundi_test,b)}) +exten => 1,n,Set(NUM=${DUNDIRESULT(${ID},getnum)}) +exten => 1,n,NoOp(There are ${NUM} results) +exten => 1,n,Set(X=1) +exten => 1,n,While($[${X} <= ${NUM}]) +exten => 1,n,NoOp(Result ${X} is ${DUNDIRESULT(${ID},${X})}) +exten => 1,n,Set(X=$[${X} + 1]) +exten => 1,n,EndWhile +\end{verbatim} +\end{astlisting} |
