Let’s start with a simple scenario involving three parties: Alice, Bob and Carol. Alice calls Bob and Bob wants to connect Alice to Carol. Bob presses the Blind Transfer button on his desk phone and types Carol’s number. His phone hangs up and Alice is connected to Carol. There is a possibility that Carol will not answer in a timely manner or will be busy talking with somebody else. In that case, it’s necessary to connect Alice back to Bob. This is easy to implement with existing teleapi features as demonstrated below.
