[asterisk-users] how to DUNDi branch office with area code?

[Bruce Reeves]

DUNDi can be used in branch office and I have a similar setup to what
your are referring with 11 sites. One thing that I decided to do, but
did not have to is define site extensions like you did, but I use the
4 digit extension locally and via dundi. Here is the details:

In my case I check for the 4 digit extension in the current site then
do a look up on dundi. Each site send the request to 2 core systems
that keep up with all the peers and forward the request on.Once the
extension is found in the dundi context on a server the call gets
routed to the correct site.By doing it this way I don't have to
remember to dial a specific number for an intra site call. The other
thing is I do I have each site a set of numbers, like 3100 - 3199 is
site B and 3200 - 3299 is C, but with DUNDi I do not have to do it
that way, it will find the extensions since I use regexten=<whatever
extension> in my sip.conf for each phone.

I hope that makes sense, JR has done an excellent job explaining DUNDi
in several white papers, and I have used something from all of them.
