Over-the-phone interpreting (OPI) is a service that connects individuals who speak different languages through a professional interpreter via telephone. It is the most widely used form of remote interpreting due to its accessibility, speed, and cost-effectiveness.

OPI is used across industries including healthcare, legal, government, insurance, and customer service. It allows organizations to provide immediate language access without the need for on-site interpreters.
