Final answer:
Handling a second incoming call while on another requires placing the first caller on hold, briefly addressing the second caller, then returning to the first. It is important to be professional and efficiently manage both calls.
Step-by-step explanation:
When you are already answering another call and a second incoming call is received, it should be handled professionally and courteously. If the telephone system has the capability, you may put the first caller on hold and briefly answer the second call, explaining that you are currently on another line. Assure the second caller you will return their call as soon as possible or ask if they would like to be placed on hold. Alternatively, if the phone system supports it, you can use the call waiting feature to switch between callers. In some cases, especially in a professional setting, a voicemail system will allow the second caller to leave a message for a callback. The key is to maintain professionalism and ensure that both callers feel their concerns are important and will be addressed promptly.
