According to CallHippo, there are two primary types of call transfers:

1. Blind Transfer: Also known as a cold transfer, this method involves transferring the caller to another agent or contact without prior communication. The recipient's phone rings, and they can choose to accept or reject the transfer. Once accepted, the original agent is disconnected from the call.

2. Warm Transfer: In this approach, the agent speaks with the new recipient before transferring the call. This allows the agent to provide context or background information, ensuring a smoother transition for the caller.
