This attribute, if set to a value of allowed indicates that incoming international reverse charged calls (from the network to the DTE) can be made to this Dna. If set to a value of disallowed, then such calls cannot be made to this Dna - such calls will be cleared by the local DCE. This attribute also currently controls access to/from the E.164 numbering plan, and if set to a value of allowed, then cross- numbering plan calls (also normal charged) are allowed. This attribute is ignored if the corresponding attribute, incCalls is set to a value of disallowed.
