Here is an example of the overall organization of a telephone call:

• The typical features of a telephone call are as follows: It begins an opening section featuring a hello or identification of the answering party. This is followed by a hello and identification of the calling party, with an exchange of how are you. Then the first topic is announced, followed by topic closing and shifts to (preferably) related topics. This is followed by a closing section consisting of elements like passing turns of okay, an identification of the type of call [ Well, I just wanted to call and … ], more passing turns, and an exchange of good-byes.
