How to Import DID Blocks Into Variphy

Applies to:

• Variphy administrators managing DID number blocks.
• IT staff responsible for UC platform configuration.
• Teams handling CUCM and/or MS Teams number mappings.

Common Causes or Issues

• When needing to import a large volume of DIDs efficiently.
• When setting up DID number mapping exceptions (e.g., fax or toll-free lines).
• When managing number blocks across CUCM and MS Teams platforms.

Prepare the Import File

1. Click on the Configure tab under DN & DID Management.

2. Download the sample CSV template using the Download CSV Template option.

The DID Import File

1. Required field: Column A must include DID numbers.
2. Optional fields:
   1. DID Range End.
   2. CUCM DN (for mapping exceptions).
   3. Route Partition.
   4. Platform Name (mandatory if DIDs belong to multiple platforms).

Note: Parentheses, hyphens, and dot notation will be stripped automatically during import.

United States/North American DID Numbers

The import file may be simplistic and only require the first column defined, or contiguous number ranges may be used. The internal CUCM DNs are not required if the DID numbers can be mapped to the internal CUCM DN.

Note: If your file includes DIDs from more than one platform (such as CUCM and Microsoft Teams), you must include a Platform Name column.

If you do not own all numbers in a range, list only the ones you do own in Column A. Variphy will automatically find the missing numbers and exclude them from the import.

CUCM DN Mapping Exceptions

Some DIDs may need to be mapped to internal CUCM directory numbers (DNs) that do not match the DID number itself. Examples include toll-free service lines, fax numbers, or any DID that routes to a non-matching internal DN. Variphy uses this mapping to correctly assign devices to these internal numbers.

You can also define Route Partition and CUCM Cluster values in the import file for these exceptions. If provided, a specific Route Partition will override the default cluster setting for that DN only.

If you leave the Route Partition field blank, Variphy will apply the default setting: Any Route Partition.

Non-US/International DID Numbers

For DIDs outside the United States or Canada, you can enter individual numbers or ranges, just as you would for North American DIDs.

Running the Import

1. In the DN & DID Management module, go to the DID Block Configure screen. Under Create DID Block, select Import DID Block(s).

2. Select:
   1. Whether numbers are US/North American or International.
   2. The prepared CSV file.
   3. At least one DID Site for assignment.
   4. Platform association mappings, if needed.

The import file may contain numerous NPA.NXX ranges within the same .csv file.

The import routine will auto-discover the number range as well as the missing DID Numbers within the ranges and create exclusions.

The newly imported DID blocks will be highlighted green in the block list.

The import routine will also identify any invalid numbers that are ignored.

Once the DID Block(s) is/are imported, they may be searched in DID Management.

For issues with DIDs not matching to the internal CUCM Directory Number(s), please see the CUCM Association section of the Configuring DID Blocks KB.
