Door Phone on BCM 400 google 03-09-09

Hi

We have a door phone setup on a BCM400. For security reasons we have
it setup so that it's not possible to dial in from an outside line and
open the door. However is there anyway of restricting which extensions
can dial the door phone extension and thus prevent everyone who has a
handset from opening the door. In our case we actually have the door
opening controller opening a lorry gate, but that's beside the point.

Any suggestions/comments welcome.

Jeremy/Bullfrog

What about creating a restriction filter with the door phone dn and
assign it to the extensions not allowed to access the door phone?
Those allowed to open the door would have an unrestricted filter.

Hi

Sorry for the long delay - misplaced my login/password. And thanks for
the suggestion.

Apparently we have tried this and either the filter is being ignored
or the exact words of the phone administrator was the extension is
being overridden. Perhaps we are doing it wrong, do you know for a
fact that this should work with extension numbers?

Thanks again

Jeremy

I tried this on our BCM and the filter is only valid on outside calls,
not intercom calls.  Are all phones in the paging group assigned to
the doorphone?  Couldn't you just unassign the phones from the paging
group that you don't want opening the gate?  As I understand any phone
that is signalled by the doorphone will see an unlock button on their
softkey.  If a phone isn't signalled it won't see this softkey.  Or
can the gate be opened another way?

This is the reason I have usually selected doorphones that are NOT
manufactured by Nortel.  They link to the system through a standard
POTS interface, allowing dialing restrictions to be applied, and most
of them allow for DTMF to open the door.
