asterisk users - Jun 2008 - How to limit extension to allow only internal calls

Hi all,

I'm playing with asterisk and I try to make system for my sister hotel 
with aprox. 40 extensions (30 rooms, 1 reception, 2 office, 4 services 
phones on each floor). I.ve installed latest version of trixbox (for 
GUI) but I made manual modifications.
This is actual server:
- n.1 Pci card with 2 x FXO + 2 x FXS
- n. 2 Trunk to outside (my local Voip provider + 1 PSTN)
I've buyed also 50 telephones from ATCOM (IP530), make all 
configurations and now seems all work fine, I can make calls (outside, 
inside) make transfer, ecc.

My problem:
I have 4 services phones (each per floor) which must be able to make 
only internal calls (not external - no PSTN nor VOiP provider), I've 
just look about solution in Google, mailing list, I can't find solution, 
please can someone give me an idea ?
NB: sorry for my english ... ;)

One option would be to reference a more restricted context in sip.conf for 
these phones.

Thanks in advance,

Context create the devices in contexts that don't have access to
outbound dialing. For example:

sip.conf
[phonewithoutbounddialing]
othersettingsgohere
context=all
[phoneinternal]
othersettingsgohere
context=internal

extensions.conf
[all]
exten => _1XXXXXXXXXX,1,Dial(whatever)
include => internal
[internal]
exten => _6XX,1,Dial(Sip/${EXTEN})

the above will work that any device starting in the internal context
will only be able to dial 6XX.

Hope this helps.

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
