Answer:
Introduce herself
Explanation:
When Channa puts the call on hold she should first indicate to the person on the first call that they will be required to wait for a few moments. When she takes up the new call she should first introduce her self, say what office the call was placed to and ask what kind of help the individual needs.
For example:
To call one: Could you kindly hold on a few minutes, please? Thank-you
To new call: Hello, This is the Medical office. My name is Channa. How may I assist you today.
