COR SET UP 2

[iptuser]

Can someone please explain in simple terms the call barring in SX2000 . I know that a COR is assigned to an extension and a COR is assigend to the route and it is the route which deteremines whether a user can dial a number

Is it that a PSTN numebr is a assigned a COR e.g
9020xxx COR 1 Local
901xxx - COR 2 NATIONAL
900XXX - COR 3 INTERNATIONAL

If you require local access only then you create a group COR 1 which contains only COR 1, for national and local you assign both cor 1 & 2 to COR group2, for local, nat and int. you assign all 3 to COR group 3. Do you then assign the COR groupd to both the user and Routes- if the user has teh same COR as the PSTN and route then it can make a call?

many thanks

Simple answer?, you know not what you ask.

Here goes.

There are 2 elements to COR restrictions.

1) COR assignment - a device is assigned a COR in the Station service assignment, Trunk Service assignment forms that gives it previledges on the system. The system does not have any restrictions by default and the restrictions that apply to COR numbers MUST be designed. Unfortunately this means that almost all systems are different. COR 1 on one system could be no restrictions and COR 1 on another could be fully restricted. It all depends on how the system is designed. The restriction is applied by the COR Group assignment.

2) COR Group Assignment - ARS Route tables need to reference a COR Group. The COR or a device is cross checked against the COR Group to determine if the call is allowed or not. If the device COR is found in the Group the restiction applies. (A co-worker of mine always says "if your in, you're out").

Simple example:

Device Cor 1,2,3,4,5
1 - No Restriction
2 - Restrict Overseas - Allow all else
3 - Restrict OS and Long Distance - Allow all else
4 - Restrict OS,LD,1-800 Numbers - allow local and 911
5 - Restrict all but 911


Cor Group entries
Group 1 - 2,3,4,5
Group 2 - 3,4,5
Group 3 - 4,5
Group 4 - 5
Group 5 -

ARS Digits/Routes

Overseas Calls send out route 1 Cor Group 1
LD Calls Send out Route 2 Cor Group 2
1-800 send out Route 3 Cor Group 3
Local Send out Route 4 Bor Group 4
911 send out route 5

The routes do not have to match the COR grps the way I have them here but I do recommend a design like this as it is much easier to manage.

COR and COR groups can be summed up with this simple statement.

"If you're in the COR, you're OUT of the call"

This means that if your device COR# is in the COR Group assigned to the ARS route, that device is restricted from making the call on that route.

It's simple when you finally understand it, but lots of people can't wrap their heads around it.
