Customer context: A customer with a cloud-hosted account wants to use the internal call feature in LiveAgent.
Customer: Do I need to add any phone number to use the internal call feature?
Answer: No, you don't need to add a phone number to use the internal call feature if you have a cloud-hosted account. To start an internal call, go to your agent panel dashboard, click on the green dot next to an agent's name, and choose the option "start internal call" or click on the + icon in top right corner and start calling internally a department or an agent there.
