Hello, you have reached the dental office of Dr. X. We are busy assisting a patient now, but will call you back as soon as possible. Please leave your name, reason for calling, and your number. If this is an urgent enquiry, please call 911. In this case, the dentist is giving a reason for not being available and they’re providing a way to prioritize the patients who need the most help. They’re also leaving an emergency number for the most severe of situations.
Solution: Make it easier for callers to reach a real person. For example, if you have multiple phone lines, Spectrum Business Voice offers you the option of setting up an auto-attendant that answers your business phone and provides callers with a menu of options—such as particular employees or departments. This way, callers are more likely to reach the people who can help them. A hunt group is another voicemail feature: If one employee does not answer their phone, it redirects calls to another phone line in your business and can keep trying all the lines you have. It will only direct calls to voicemail if no one answers their line.

The insurance agent is quite polite in his approach towards his clients. He is also eager in extending his help to the client.
