Telephone Etiquette จริยธรรมการพูดโทรศัพท์
The telephone is your link to the
outside world. Through the telephone
we give and receive information, pass
instruction to the people and
establish and strengthen business
relationships. Much business and
professionalism over the telephone
are as important as in face-to-face
contact, so your telephone skills give a
positive or a negative first impression.
