You may import up to 5,000 CNAM, LIDB, and call forwarding line features in bulk using the Upload Line Features page in the Bandwidth Dashboard. Before we begin, let’s review what each one of them does:

  • CNAM (Caller Name) feature allows end users to see inbound caller ID on their phone.
  • LIDB (Line Information Database) feature allows you to manage the outbound caller ID display.
  • Call forwarding feature allows you to redirect incoming calls to an alternate phone number.

To bulk import CNAM, LIDB, or call forwarding, please have the list of phone numbers (TNs) you'd like to update ready.

  1. Log into the Bandwidth Dashboard.
  2. In the top navigation bar, click Numbers and select Upload Line Features.
  3. Click download a template .csv file link. Once you download the .csv file, please open it.
    • Note: If you don't see the file, check the Downloads section in your browser or the Downloads folder on your computer.

We know this template may look a bit overwhelming at first, but it’s actually quite simple! The first row represents the line feature, such as LIDB, while the second row represents the field, such as Name. We also included some examples in rows 3-6 to show how your data needs to be formatted. Please delete that sample information prior to entering your own.
