HI Guys,
I have used the following method to block 800(8xx) numbers and it works good
so far. I was wondering whether we can use dial pattern to simplify it. I
was trying to define some "constant variables" in "globals", like A=800,
B=866, etc. Then, use "exten =>647xxxxxxx/_[${A}${B}${C}].,1,Hangup." The
goal is to use this one config and it represent all 800, 866, 877, etc
numbers. I tried to use my two cellular phone (which has middle number of
648 and 474) to test out, it seems not successful. Does anyone know how to
do this ?
[globals]
;Ring time
RT=60
;Toll-free numbers
A=800
B=866
C=877
D=888
E=648
F=474
[default]
exten => _X.,1,Hangup(3)
[sipdefault]
exten => _X.,1,Hangup(3)
[unlimitel-inbound]
;exten => 6477226968/_416[${E}${F}].,1,NoOp(20)
;exten => 6477226968/_416[${E}${F}].,n,Hangup
;/_[${A}${B}${C}].
exten => 6471234567/_800.,1,Hangup
exten => 6471234567/_866.,1,Hangup
exten => 6471234567/_877.,1,Hangup
exten => 6471234567/_888.,1,Hangup
exten => 6471234567/_1800.,1,Hangup
exten => 6471234567/_1866.,1,Hangup
exten => 6471234567/_1877.,1,Hangup
exten => 6471234567/_1888.,1,Hangup
Thanks in advance.
