Summarize the following:
What is appropriate for some is not always appropriate for other people, and this can cause a fair amount of problems when misunderstandings arise.  For example, many customers prefer to get straight down to business and value speed and efficiency; however, some clients prefer to essentially "chat" for a short time to build a brief personal connection,trust before moving on to the main purpose of the call. Another major consideration is in regard to time zone differences. In many parts of the world, phone workers call during their daytime, but it may not be daytime on the other side of the world where the client is. Many people, when interrupted during their sleep, or during mealtime or family time when outside of work, may find such intrusions intolerable. Avoid mimicking the person's accent, or using slang that is local to your client's area or culture on the other end of the phone. In some cases it can be acceptable and make the person receiving the call feel more at ease, but this is actually a very small and rare demographic. Many people find a false accent to be insincere and fraudulent, or copying an accent as a sign of disrespect.
Consider the cultural influences of your customers.
