What's the most important guideline for phone interactions?

Starting a call with a smile is crucial because it sets a positive tone for the interaction. Though the customer cannot see you, a smile can be reflected in your voice, conveying warmth and friendliness. This approach fosters a more personal connection and helps put the customer at ease, creating an atmosphere more conducive to effective communication and problem-solving.

When customers feel welcomed and valued right from the beginning, they are more likely to engage openly and share the necessary details to address their concerns fully. Establishing rapport through positive verbal cues can lead to a more successful resolution of the customer's issue, as they are more comfortable expressing their needs and feelings during the call.

Other options, while they may have their own merits in different contexts, do not prioritize the emotional connection and rapport-building that a warm introduction facilitates.
