inhibit reception of external calls

[bubucatrame]

Hello
I bought a ring-detector that i use to
grant access to the parking with a bar.
The detector is attached to a analogic
line of my md-110 system. I would have
this bar actioned ONLY from internal
numbers.How can I exclude EXTERNAL calls
to ring in this line?
How can I implement this feature without
creating a category or a customer?
(in other words, only acting on that number...)
Any idea?

Sorry for my bad english,
best regards

If it is a Analogue extension you can set SERV D5 to block it for traffic from a public exchange. From a Tie Line the number will still be reachble though.

Another way would be to give this extension a seperate Traffic Matrix class which only can be dialed from internal extensions.

I've modified SERV D5 and it worked very fine.
Thank you very much.

Probably the most simple way would be to give the extension a number from a non DDI EX number range.
