What is the importance and advantages of telephoning?

For business and professional use, the telephone is an effective oral communication tool and one of the most important channels of communication. Often a telephone conversation can take the place of two written messages or a face-to-face interview. In most of the cases communication through telephone is comparatively less time taking and more economical. Telephone talks are also more effective in some cases than the written messages. Something difficult to say in face-to-face interview, can be easily said on telephone. The time that phone calls save to handle certain inquiries and business is valuable for both the callers and the respondents. Business may also sell goods and services through telephone calls. It is a medium, which helps contact more customers, more frequently at lower cost, and earns money from sales. The telephone is therefore, useful in saving money, time and labour, and increasing efficiency and revenue.
