Step 3: Assemble and Connect Your Phone
Assemble the phone by attaching the handset and stand. Connect the phone to your network using the provided Ethernet cable. It is recommended to connect via Ethernet initially for the phone to register with Ooma and download custom settings, even if you plan to use Wi-Fi later. Once registered, you can configure Wi-Fi settings through the phone's menu or Ooma's online interface.

Maintenance
To ensure the longevity and optimal performance of your IP phone, follow these simple maintenance guidelines:
