The VoIP gateway matches the rules starting at the top of the table. 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 VoIP gateway applies rule 1 to numbers that starts 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 VoIP gateway applies rule 1 to all numbers that start with 55 including
numbers that start with 551.
