Create a Customer Dial Plan

This procedure determines the type of Cisco HCS dial plan schema (Type 1 to 4) to be used, depending on how you fill in the form.

Note

You can have only one dial plan per customer. If you try to add a second dial plan, the dial plan will fail. Once you have created the customer dial plan, Enable CSS filtering is the only setting that you can modify.

Procedure

  1. Log in as provider or customer administrator. For a list of the roles and tasks that can be done at each level, see see Roles and Privileges.

  2. Choose Dial Plan Management > Customer > Dial Plan.

  3. Click Add to add a Customer Dial Plan.

  4. Perform one of the following:

    • If a Site Location Code is required for this customer, select the Site-Location Code (SLC) based dial plan? check box, OR
    • If an SLC is not required, go to Step 8.

  5. Perform one of the following:

    • To add an extension prefix for the dial plan, select the Use extension prefix? check box. Enter the extension prefix in the form and go to Step 8.
    • To add an ISP for the dial plan, select the Inter-Site Prefix required for inter-site dialing? check box. Enter the Inter-Site Prefix (ISP). The ISP can be one digit in length.

  6. If the ISP should be included in the directory number, select the Is ISP included in directory number? check box. If not, go to Step 8.

  7. If the ISP should be included as part of the Voice Mail ID, select the Is ISP included in Voice Mail ID? check box. If not, go to the next step.

  8. Select the Enable CSS filtering check box to filter the calling search spaces available when configuring a Subscriber, Phone, or Line, to site level Class of Service calling search spaces. Filtering is disabled by default, which results in all available Cisco Unified Communications Manager calling search spaces being available when configuring a Subscriber, Phone, or Line.

  9. Click Save to add the Customer Dial Plan you defined.

    Note:

    The Customer ID is a unique, auto-generated, read-only number allocated to the customer. The Customer ID is particularly useful in shared deployments (where a cluster may be shared across multiple customers) to correlate specific elements to a customer. It appears in the Cisco Unified Communications Manager as an prefix to elements (for example Cu2Si7 identifies Customer 2, Site 7).

    Note:

    The Cisco HCS dial plan schemas are configured such that the customer-level dial plan elements are not pushed to the Cisco Unified Communications Manager until the first site for the customer is deployed. Therefore, you will not see any dial plan elements provisioned on the Cisco Unified Communications Manager until at least one site is deployed for the customer. See Create a Site Dial Plan.

    Note:

    When adding lines (DNs) at the site level, you must remember to define your DNs appropriately (that is, you are responsible for using ISP+SLC+EXT if you deploy a Type 2 dial plan). Otherwise your inter/intra site calls won’t route. To define your directory numbers, refer to Add Directory Number Inventory.
