Explanation
In Cisco Unified Communications Manager (CUCM), digit discard instructions are used in digit manipulation to strip portions of a dialed string before routing. The three valid options are: PreAt (A) - discards all digits before the '@' symbol, commonly used in URI-style dial strings; PreDot (B) - discards all digits before the '.' (dot), which is the most common instruction used to strip an outside access code (e.g., the '9' in '9.XXXXXXXXXX'); and Trailing# (E) - removes a trailing '#' character that a user may dial to signal end-of-dialing. PostAt, Leading#, and PostDot are not standard CUCM digit discard instruction names.
