Welcome to the Spearline Knowledge Center

Map a specific conference number to be used as a Direct Dial-in number (DDI).

Note: Each phonegroup can only have one DDI number mapped. Any numbers that are using the same phonegroup will use the DDI that is mapped for that phonegroup.

To set or change a DDI number, do the following:

1. Navigate to the DDI module here (this is nested in a tab which is located along the top of the page under the Numbers module).
2. Search the list using the filters provided to find the Phonegroup, Region or Bridge you wish to map the DDI number to.
3. Click the Change DDI button (this is located on the right hand side of the DDI list view).
4. Search for available numbers assigned to that phonegroup and use the Radio Button to select the number/country you wish to use.
5. Select the IVR Traversal to be used on the DDI using the DDI IVR Traversal drop-down menu.
   Note: If no IVR traversal is selected for the DDI it will revert to the IVR traversal that was set when the conference number you have selected was first entered into the platform.
6. Click the Submit button to complete your task.
