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 FXO1 line 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, which change
the callee number to 8888 )
2.
Redirect the caller '13910122334' from FXO1~4 line 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, which
change the callee number to 8888 )
3.
Redirect all calls from GSM1~2 line during off-work time to 9999 of IP-PBX. (Redirect to
IP-PBX is routing, 9999 is the result of number transform, which change the callee number
to 9999)

Filter
Call filtration determines what kind of calls is allowed to get through the gateway. It looks like
some black and white lists. There are some parameters and strategies. There are created filter
rules based on the created time. In process, the system will match this rule list with current call
information until find the perfect one. There is at least one rule which is the default one that can
be changed but not removed.
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.
