1-VoIP Promo Code Black Friday 2026 - 50% OFF

1-VoIP is a privately held company based in Tulsa, Oklahoma, that has sold voice over Internet Protocol phone service to households and businesses since 2005. It markets itself as a lower-cost replacement for a traditional landline, and its plans come without a long-term contract, backed by support staff located in the United States.

For residential customers, calls travel over an existing high-speed internet connection rather than a phone line, and an adapter supplied by the company lets people keep using ordinary telephones. Numbers from a previous provider can usually be moved over, so a household does not have to give up the number it already has. Billing runs month to month, so service can be stopped without a penalty.

Business accounts get more control over how calls are handled, including SIP trunking, customizable call queues and virtual receptionist features, along with a mobile app for managing calls away from the desk. The company works closely with clients to shape a setup around their needs, and it leans on its customer care reputation as a selling point.

The catalog covers a range of calling features and call-management tools rather than hardware, keeping the focus on service and support.

Codes go into the promo code box at the 1-VoIP checkout; deals need no code.

1-VoIP has official accounts on Facebook and Twitter.
