The ooma Scout is a device that interoperates with the ooma Hub to allow access to the same functionality as the Hub, but from any phone jack in the house. The Hub allows users to make unlimited national calls free of charge. Rather than a monthly fee for service, all expenses are paid upon purchase of the Hub, which connects with both a standard phone line and an Internet-dedicated line to offer the service using VoIP. Features include the standard caller-ID, call-waiting, and voicemail, as well as landline-comparable quality, the ability to access voicemail from any phone, and voicemail notifications sent to email and cell phone. Users can choose a new phone number or keep their existing number.

ooma also offers a paid, Premier service ($12.99/month or $99.99/year), which includes features such as a second line that allows two users to talk simultaneously to two separate callers, three-way conferencing, and call forwarding to another number. Premier users also have access to voicemail features like message screening, transferring a call to voicemail, voicemail forwarding, and the option for calls to go directly to voicemail without the unit's ringer sounding. The ooma Scout measures 3.2 inches deep by 4 inches wide by 1.5 inches tall, and weighs 8 ounces.
