Export and Import Allowed Numbers

Cloud Voice lets you download your allowed numbers as a CSV (comma-separated values) file. That file doubles as a template: edit it offline to add, remove, or update entries, then upload it back to apply your changes in bulk.

Note

PBX stands for Private Branch Exchange, the phone system that routes your calls. The Allowed Numbers list lives in the PBX web portal under Call Features > Blocked/Allowed Numbers > Allowed Numbers. Exporting and importing let you manage the whole list at once instead of editing entries one by one.

Export allowed numbers

Exporting writes every allowed number to a single CSV file that you can review and modify.

1. Sign in to the PBX web portal and open Call Features > Blocked/Allowed Numbers > Allowed Numbers.
2. Click Export.

The CSV file downloads to your computer. For field-by-field guidance on what each column means and how to fill it in, see Allowed Numbers Parameters.

Import allowed numbers

Tip

Export your current allowed numbers first and use that download as your starting template. Working from a valid file is faster than building one from scratch and avoids formatting mistakes.

Before you import, make sure your file meets these requirements:

• Format: UTF-8 encoded .csv (UTF-8 is a text encoding that keeps every character readable)
• Size: under 50 MB
• File name: fewer than 127 characters
• Contents: every column must satisfy the field rules described in Allowed Numbers Parameters

Caution

The import fails if the file breaks any of these limits, so check them before you upload. Save the file as UTF-8: another encoding can garble digits or cause the upload to be rejected. Keep the file under 50 MB and its name shorter than 127 characters.

To import:

1. Sign in to the PBX web portal and open Call Features > Blocked/Allowed Numbers > Allowed Numbers.
2. Click Import.
3. In the dialog that opens, click Browse and choose your prepared UTF-8 .csv file.
4. Click Import.

When the import finishes, the numbers from your CSV file appear in the Allowed Numbers list.
