[asterisk-users] How to limit extension to allow only internal calls

[Rizwan Hisham]

There is another easier and interesting thing you can do in extensions.conf
to restrict specific dialinmg codes for specific users.

suppose your internal extensions are 4 digits long. your service phones have
did 1111, 1112, 1113.here is the dialplan for all of your phones including
service phones:

[hotel]
;for all other phones
exten=> _1XXXXXXXXXX,1,Dial(${external})
exten=> _011.,1,Dial(${internaltional})
exten=> _XXXX,1,Dial(${internal})

;for service phones
exten=> _1XXXXXXXXXX/1111,1,hangup
exten=> _1XXXXXXXXXX/1112,1,hangup
exten=> _1XXXXXXXXXX/1113,1,hangup
exten=> _1XXXXXXXXXX/1114,1,hangup

exten=> _011./1111,1,hangup
exten=> _011./1112,1,hangup
exten=> _011./1113,1,hangup
exten=> _011./1114,1,hangup

if you dont want to define separate context for every person you can match
his did just like above. This way whenever service phones try to dial a
local or international number they will hangup instead and all other phones
will be able to dialout. try it
