Begin by reviewing the PowerPoint presentation on Telephone Etiquette to understand the key points and best practices. Then, consider incorporating role-playing exercises into the training program to allow receptionists and secretaries to practice handling various phone scenarios. Provide feedback and guidance during these exercises to help them improve their communication skills. Additionally, discuss the importance of active listening, professional language, and maintaining a positive tone during phone conversations. Encourage participants to ask questions and seek clarification on any aspects they find challenging. Finally, conduct mock phone calls to simulate real-life situations and assess their progress. By combining theory with practical exercises, you can effectively enhance the telephone etiquette skills of receptionists and secretaries.
