Sometimes it can be advantageous to make it easy for your customers to reach the person they need directly. With Ooma Office, you can map one or several phone numbers to a single extension.

By default, the outgoing caller-ID for each extension will be the primary business phone number. If you have one or more phone numbers mapped to an extension, however, you can choose one of those other numbers as the extension’s outbound caller-ID.
