I would love to have the ability to both search for extensions and create new user extensions via some form of regex or wildcard extension format. For example when creating a new user, we are asked to choose an extension number. We have specific roles in our organization we like to keep within the 7000 range of extensions. Currently, I have to go searching for the next availabe extension in that pattern.

1. It would be great if I did not have to go searching at all and could just enter something like 7*** or 7### and the system would assign the next sequentially available extension in that pattern. Would be awesome if this were implemened on the API side too.

2. Within the search functionality it would be great to have the capability to search within the same pattern framework. For example, if I am looking for all extensions in the 7100 range, I could type 71##. My problem currently is that the best search I can do when searching for 7000 range numbers is "7". Since most of our company numbers include "7" in the area code and number, this doesn't really eliminate much.
