The assistant handles the call politely but avoids transferring the caller to her boss. She states multiple times that her boss is unavailable or busy. When the caller asks to send information about his products, she finally suggests this but should have done so sooner rather than wasting time. Ideally, she could have politely declined interest upfront instead of prolonging the call. Cold calling involves unsolicited calls to prospects not expecting contact, usually as the start of a telemarketing sales process.
