What is the primary use of the conference feature described in the material?

• A. Language line
• B. Billing
• C. Recording
• D. Customer survey

Answer: (A)

The conference feature is used to bring multiple participants into one call so language support can be added in real time. In the material, its main purpose is to connect a language line or interpreter to the conversation, enabling accurate translation so both sides can understand each other. This makes it ideal for situations where language differences could impede service. It isn’t described as the primary tool for billing, recording the call, or conducting a customer survey, which are different functions.
