Restriction Filter Issues with BCM 400

[rax3691]

Hello guys, I'm having a hard time understanding the way the restriction filters should be applied to our user's passwords making calls thru a Nortel BCM 400.

I need to restrict/avoid international calls and calls to cell phones. Calls to local phones are the ONLY ONES, that WILL BE ALLOWED.

Here in this country all cell phone numbers begins with "7", and our carrier to overseas calls is "158". All users after have entered their password need to dial "90" to make LOCAL CALLS. Again, those will be the only calls allowed in our company.

Hence the correct order to dial a cell phone would be:
Function 68 + PASSWORD + 90 + 7...

And to make an international call:
Function 68 + PASSWORD + 90 + 158 + 00 + ...

So I have created the restricton filter like this:

"90A" with exception "902A", to allow local phone calls.

But once I have applied the filter into any password at:
Configuration/Telephony/Call Security/Class of Service

either into the "Set Restriction Filter" or "Line Restriction Filter" or in both, it indeed is avoiding to make calls to cell or international phones. The problem is that it is also blocking my local phone calls. I CANN'T EVEN MAKE LOCAL PHONE CALLS! WHY ???

The steps to make local calls would be:
Function 68 + PASSWORD + 90 + 2...

So if have not blocked the digit "2" after "90", but by the contrary, I have allowed it (with the exception "902A"), WHY IS BLOCKING MY LOCAL PHONE CALLS ???

I will really appreciate the solution to my problem.

TIA!

try making it 902 instead of 902A

If I make it like that, shouldn't I be allowing to the dial just "902" ????

Users need to dial 90 + 2 + [local phone number]

Ok I made it as you said and it didn't work. That's still allowing me to make calls to cell phones and overseas calls.

Check the above example, to understand the way users make local phone calls.

They need to dial 90, followed by the local number which always begins with "2". Got it?

Is "90" a pool access code or a destination digit in routing? Why not restrict everything with "902" as the override?

Well, let me tell you something...

This is my 1st. time working with a device like this, (well in fact is my 1st. job in the communications field) so I'm sure if that's a pool access or a destination digit, what is and for what is a "pool access" ?

AFAIK "90" is the number we dial/pick to make local calls, that's why we after typing 90, we dial the local phone numbers.

I received this device being a total mess in its configuration, and since I'm not expert in this, the situation gets harder.

So since I'm not sure I better provide you with the images like they are so you can check them:

Now I don't understand why you said:
Why not restrict everything with "902" as the override?

I'm not wishing to restrict local calls (all of them begins with "902") ???

Let me tell what additional information can I provide, so you can help me with this.

TIA

Looks like you are using COS passwords.
First thing you need to do is to create a filter with the barring numbers you require,
EG. set up filter 07 (Call security-restriction filters)
then add the barred digits folloxed by the exception digits(calls allowed).
EG..filter 07--barr(add) A =(all digits).
then select(Highlite)A the exception tab opens.
Enter the allowed digits 2 (for local calls).
This now will create a filter called 07 that barrs all calls except those that begin with 2.

Now you assign this filter either to the extn directly or to the COS password fillter replacing the default filter.

So when the user uses f68-password 90-(the filter 07 is applied)to the password.

I am assuming 90 is the external dialing code for external lines.

The COS password is used to override restrictions on the extn the person is dialing from.

Normally in your case the extn would be barred all calls then you have to use a password to bypass this.

My advice would be to replace the extn filter with the new one created (07) and not use passwords.
this way the user only needs to dial 90 for external line and the filter does the rest of the barring.
You can then assigned this filter to all the extns that requirethe same level of barring.

To add to snowman the restriction should not start with 90 that is the route you use the digit to restrict.
