Right now it seems that anyone can dial *93 from any extension, enter any other extension to forward, then enter any number to forward said extension to. This is concerning as a malicious person could forward our Director’s extension to the local bar down the street, or perhaps even their own cell phone.
Is there a way to restrict the usage of *93? Perhaps just to certain extensions, or maybe make it so that only certain extensions can do *93 on certain extensions?
A list of ‘regexes’ that the phone will accept as legitimate dial patterns and pass so to the server ‘1NXXNXXXXXX|*XX|[2-9]XXX|011XXXXXXXXXX.’ for a simple example , here you can 11digit dial NANP numbers, all feature codes that match * and two digits , and all your extensions are between 2000 and 9999 and any international number longer than 10 digits. It is either set on the phone, or provided by your provisioning service
