OCS Enterprise Voice Policy
An OCS Enterprise Voice Policy is essentially a Class of Restriction (COR) which can be assigned to Enterprise Voice users at either the global or user level. Phone Policies are defined within the OCS Location Profile. The OCS Location Profile contains other voice configuration settings but this blog focuses solely on defining Voice Policies.
Below is diagram which Gold Systems has used to explain the concept to our customers.
The OCS Location Profile first needs to be defined. Once that is done you create your normalization rules. Normalization rules are a set of administrator-defined digit manipulations. I’m intentionally skipping over normalization rules for purpose of this discussion. The one thing to keep in mind is that for numbers that are normalized, the resulting translated number must have a matching route in OCS. The Route is what OCS uses to decide if a number should be forwarded to a gateway (mediation server).
The diagram above contains four Voice Policies. Each one of the policies contains one or more phone usages.
The Internal Dialing Policy contains the Emergency and Internal Phone Usages. The Emergency phone usage is assigned the 911 route and the Internal phone usage is assigned the four digit (4D) internal extension range. This policy would be ideal for a company’s Front Lobby phone. It would allow company visitors to call 911 or internal extension ranges.
The Local Dialing Policy contains the Emergency, Internal, and Local phone usages. Each phone usage contains its respectively assigned route. This policy would limit someone to only dialing 911, 4D internal extensions, and local 10 digit numbers.
The Long Distance Dialing Policy contains the Emergency, Internal, Local, and Long Distance phone usages. This policy allows all the dialing privileges of the Local policy plus 11D long distance.
Finally, the International Dialing Policy provides unsrestricited dialing capabilities.
The OCS Enterprise Voice Policy configuration in the diagram above has satisfied the requirements of about 80% of our customers. You can definitely get more granular and limit calls to specific LD and International numbers, etc. This configuration is simply a high-level example to get you started, and help you create your own Enterprise Voice Policies.
