So I work for a school district and am decent at working my way through our cisco phone system. But I have a specific type of search i would like to do if possible. I am looking to see if there is a way to search for external phone number masks. I have a number that was called out, and I know that phone/ext that it is connected to but I would also like to double check and make sure that number is not listed as the external phone number mask of some other extension. (Hopefully that all made sense) And secondly I have done this before but cannot remember how I did it. But how to search for who called out to a specific number, like in this schools sometimes kids will dial 911 as pranks or something. And we will need to track down where it came from. So if anyone has any experience with that let me know or point me in another direction, thanks!
