BASIC PRINCIPLES FOR UNDERSTANDING ARS MECHANISMS
For a particular prefix, it is possible to define several ranges
36123 dialed -> selection of the first entry (123 belonging to the range 0-1).
368899 dialed -> selection of the second entry (8899 belonging to the range 87-97).
3699 dialed -> selection of the third entry (99 not belonging to any range defined for the prefix 36).
If a range covers other prefixes for outgoing calls, the first range corresponding to the digits
dialed is selected
3655 dialed -> selection of the first entry (55-66 included in 5-6).
36889 dialed -> selection of the first entry (888-999 included in 88-99).
Different ranges cannot be defined between the fields "Prefix" and "Substitute"
36 [01-03] cannot be replaced by 03886777[51-53] -> 3 entries have to be created in the ARS table.
