Thank you for the reply, But I need to have the extension inside my DID range for the pots 1 and 2 and have a specific extension off of the DID range. These are for fax machines. Basically what is happening is we have an IPO 406, 2 digital modules 16 port each and an analog module 8 port. The problem is we only have 40 DID's. SO I guess im asking how to move around the extension so I can assign specific extension the we already committed to with the extensions for the fax machines.
