DUNDi Lookup and Extension Registry Proxy
This module provides a proxy for the extension registry feature in FreePBX. If you have a DUNDi trunk configured in FreePBX to other branch offices, and a route defined to access it, then this module will proxy and check for extension number duplication in other branch offices when creating new extensions, ringgroups or any other extension that can be dialed.
The module does not consider the outbound dialing rules. It simply checks the DUNDi cloud down all configured DUNDi routes, and if another system indicates they have that extension, then it will consider this a conflict and report it back as such since a change in routing rules would easily expose this conflict.
As a secondary function, the module allows you to easily check for numbers present within the configured DUNDi routes in a simple GUI page.
