Description: This attribute, together with the forceNpiTon attribute, controls Numbering Plan Identifier (NPI) and Type Of Number (TON) values to be used by the SigChan component for egress calls (if applicable). The combination of NPI and TON values defined by the defaultNpiTon attribute is used for an egress call whenever: - the call setup message received from subnet indicates that NPI or TON information is not supplied or doesn't make sense, or - attribute forceNpiTon is set to yes Mapping between values of the defaultNpiTon attribute and associated combinations of NPI and TON values follows: casUnknown: NPI=unknown (0) TON=unknown (0) unknown: NPI=E.164 (1) TON=unknown (0) international: NPI=E.164 (1) TON=international (1) national: NPI=E.164 (1) TON=national (2) subscriber: NPI=E.164 (1) TON=subscriber (4) p0: NPI=private(9) TON=0 p1: NPI=private(9) TON=1 p2: NPI=private(9) TON=2 p3: NPI=private(9) TON=3 p4: NPI=private(9) TON=4 p5: NPI=private(9) TON=5 p6: NPI=private(9) TON=6 p7: NPI=private(9) TON=7
