Replace N digits from the head of caller or callee number:
replace
N
(
N
>=1) digits from
the head of caller or callee number with another number. If
N
is more than the length of caller
or callee number, replace the number with another defferent number completely. For example:
replace 3 digits from the head of '10086' with '200', it should be '20086'.
•
Replace N digits from the tail of caller or callee number:
replace
N
(
N
>=1) digits from the
tail of caller or callee number with another number. If
N
is more than the length of caller or
callee number, replace the number with another defferent number completely. For example:
replace 2 digits from the tail of '10086' with '68', it should be '10068'.
•
Calculate the last N digits of caller or callee number with an integer I:
add an integer
I
to
the last
N
digits of caller or callee number and gain a new number.
I
should be equal to or more
than negative 9999, and be equal to or less than 9999 (-9999<=
I
<=9999). This action only
works on the last 4 digits of the phone number and does not care the carry. For example: the
old extension numbers are from 7001 to 7050, another system has a segment from 2301 to
2350, you may execute
I
=-4700 to reflect these two segments.
For example:
1.
Redirect all the calls from Slot 1-1(FXO) port to 7777 of IP-PBX 192.168.11.22, the others to
8888 (Redirect calls to IP-PBX is routing, 8888 is the result of number transform).
2.
2.Redirect the caller '13910122334' from Slot 1-4(FXO) port to 8888 of IP-PBX
192.168.11.22. (redirect to IP PBX 192.168.11.2 is routing, 8888 is the result of number
transform).
3.
3.Redirect all calls from Slot2(T1/E1) line during off-work time to 9999 of IP PBX (redirect to
IP PBX is routing, 9999 is the result of number transform).

Filter
Call filtration determines what kind of calls is allowed to get through the gateway based on various
parameters and rules. It looks like some intelligent black and white lists.
The page has two areas: the list area and the edit area:
•
The list area: show the call filtration list.
•
The edit area: set the parameters of call filtration record.
Note:
For register FXS line, you do not need to set alter strategy for numbers, which means
the system will not show your FXS line in the items of
Source Line
,
Destination Line
settting.
