Final answer:
Effective telephone communication requires speaking clearly at a moderate rate and volume, enunciating jargon, and using respectful language to ensure understanding and professionalism.
Step-by-step explanation:
In order to remain effective when communicating by telephone, one should speak clearly at a moderate pace. It is crucial to enunciate specific terms or jargon, use respectful language, and avoid text language such as "u" for you and "r" for are, as this is not considered proper business communication. Speaking slowly and clearly is beneficial for ensuring the listener can understand you despite potential technical issues like Wi-Fi delays or microphone malfunctions. Additionally, the use of a moderate volume is essential to maintain a pleasant conversational tone without being too loud or too soft. Proper emphasis on these elements of communication ensures the message is conveyed effectively and professionally.
