Lower your ringer. Don't make lame excuses about being rude . Use your voice-mail function . You can personalize and add some humor to voice mail message. The phone ringing is an option not a mandate.
Elevators drop calls.
End the call before you enter the elevator. Makes you look dumb to the customer, and the people in the elevator. When you get a call and you're with others, 30-seconds is the maximum. Eliminate triple jeopardy . It puts you in a bad light and makes appear rude and look foolish.
