Prefix
The prefix specifies a series of digit sequences. When you dial a
series of digits, each sequence in the prefix is tested as a possible
match. The matching sequences form a set of candidate digit
sequences. The phone number set here is used to add, strip, or
replace the OP number.
Mode
None: No action.
Add: When you choose this mode, the OP number will be added
with the prefix number for calling out through the specific phone
interface.
Replace: If you select this mode, the OP number will be replaced by
the prefix number for calling out through the specific phone interface.
Delete: If you select this mode, the OP number will be deleted by the
prefix number for calling out through the specific phone interface.
Restrict: If you select this mode, the OP number will be restricted by
the prefix number for calling out through the specific phone interface.
OP
Number
The front number you type here is the first part of the account
number that you want to execute a special function (according to the
chosen mode) by using the prefix (number). If you selected the mode
"Add", “Replace”, or "Delete", the OP number will be applied in this
rule.
Min Len
Set the minimal length of the dial number for applying the prefix
number settings.
Max Len
Set the maximum length of the dial number for applying the prefix
number settings.
Interface
You can apply the prefix number settings to the PHONE port (Phone
1).
Example:
z The first rule accepts calls using 03 as the prefix number. For example, if
you dial "038993765", it matches this rule and the VoIP Adapter will make
the phone call "886038993765".
z The second rule accepts calls using 06 as the prefix number. For example,
if you dial "065991234", it matches this rule, and its length (not including the
length of the prefix) is 7, between 6 (Min Len) and 8 (Max Len), therefore
the VoIP Adapter will make the phone call "065991234".
z The third rule accepts calls using 9 as the prefix number. For example, if
you dial "93652400", it matches the third rule and the VoIP Adapter will
make a phone call "08003652400".
