CO line Allow/Deny Restriction Rules
If there are no entries, no restriction is provided by the table.
If there are entries in the Deny table, then the restriction is on a Deny Only basis.
If there are entries in the Allow table, then the restriction is on an Allow Only basis.
If there are entries in both the Allow and Deny Tables, the Allow Table is searched, if the
dialed number matches an entry in the Allow Table, the call is allowed. If a match is not
found, the Deny Table is searched and if a match is found in the Deny Table the number is
restricted. Otherwise, the number is allowed.
If Incoming CO Call Toll Check is set, the COS rule is applied when the station dials
digits after answering incoming CO calls.
