Permissive dialing

Permissive dialing refers to a telecommunication feature that allows users to place calls using a broader range of dialing patterns or prefixes without strictly adhering to standard dialing protocols. This can include dialing from different formats (like including or omitting area codes), using alternative numbers or prefixes, and sometimes allows for the use of non-standard sequences to complete calls. The intent behind permissive dialing is to enhance flexibility and convenience for users, making it easier to place calls without needing to remember exact dialing sequences.
