Table 3-41: Npi/Ton Values For Isdn Etsi - AudioCodes Mediant 2000 User Manual

SIP User's Manual
The device matches the rules starting at the top of the table (i.e., top rules take precedence
over lower rules). For this reason, enter more specific rules above more generic rules. For
example, if you enter 551 in entry 1 and 55 in entry 2, the device applies rule 1 to numbers
that start with 551 and applies rule 2 to numbers that start with 550, 552, 553, 554, 555,
556, 557, 558 and 559. However, if you enter 55 in entry 1 and 551 in entry 2, the device
applies rule 1 to all numbers that start with 55 including numbers that start with 551.
