Creating DDIs for Voice Mail Pilot Numbers
------------------------------------------

Before You Begin
................

To create a DDI for a voice mail pilot number, perform the following steps on
VOSS-4-UC. The voice mail pilot number must be
created before performing this procedure. See Define a Voicemail Pilot Number.


1. Log in to VOSS-4-UC as a Provider, Reseller,
   or Customer administrator.         
2. Use the breadcrumbs to navigate to the customer hierarchy node that contains
   the voice mail pilotnumber.                                                  
3. Select **Device Management > CUCM > Route Patterns**.
4. Select **Add**.
5. Create a new route pattern instance with the following information:

   a. On the **Pattern Definition** tab, complete the following item:.

      i. **CUCM**: Select the appropriate Cisco Unified Communications Manager
         cluster for this route pattern. This should be the cluster on which you
         created the voice mail pilot.                    
      ii. **Route Pattern**: \+<E.164 number>: Enter an appropriate DDI number.                         
      iii. **Route Partition**: Cu<customerId>-E164LookUp-PT 
      iv. **Route List**: From the drop-down, choose the appropriate route list
          for the target voice mail pilot number. The pilot number will be in  
          the route list name. Example:                 

          Cu<customerId>-<voicemail service name><targetVM pilot number>-RL, Cu5-TestVmService1000-RL   
                                                           
   b. On the **Called Party Transforms** tab, enter a pilot number in the Called
      Party Transform Mask field; for example, 1000.
6. Select **Save**.
7. Repeat these steps for each voice mail pilot number.     

   .. note::
                                                            
      This route pattern needs to be deleted from **Device Management > CUCM > Route Patterns**
      before the voice mail pilot can be deleted. This is because this new route
      pattern will still reference the pilot-specific route list, causing the voice
      mail pilot number delete workflow to fail. If this occurs, delete the route
      pattern and attempt to delete the voice mail pilot again.
