Alter Rules
The rules are:
•
Strip caller or callee number from head:
strip
N
digits from the head of caller or callee
number. N must be equal to or more than 1 (
N
>=1). If
N
is more than the length of the caller
or callee number, give up this operation. For example: strip 3 digits from the head,
01082356031becomes 82356031.
•
Strip caller or callee number from tail:
strip
N
digits from the tail of caller or callee number.
N must be equal to or more than 1 (
N
>=1). If
N
is more then the length of the caller or callee
number, give up this operation. For example: strip 3 digits from the tail, 95588123 becomes
95588. But this function is seldom used.
•
Add a prefix to caller or callee number:
add a
N
digits prefix on the head of caller or callee
number and make a new number. N must be equal to or more than 1. For example: pre-pend
'17909' to '02088786688', so the final number is '1790902088786688'.
•
Add a postfix to caller or callee number:
add a
N
digits postfix on the tail of caller or callee
number and make a new number.
N
must be equal to or more than 1. For example: append
'.7788' to '02088786688', so the final number is '02088786688,7788'.
•
Keep N digits from the head of caller or callee number:
keep
N
digits from the head of
caller or callee number. N must be equal to or more than 1. If
N
is more than the length of
number, keep it completely. For example: keep 5 digits from the head of
'9558823423453451311', it should be '95588'
•
Keep N digits from the tail of caller or callee number:
keep
N
digits from the tail of caller
or callee number.
N
must be equal to or more than 1. If

'7007'.
•
Replace caller or callee number:
replace caller or callee number with a completely defferent
number. For example: replace 10086' with '10088'.
