Gesture & etiquette
Pick up a notepad immediately to be ready to take notes; repeat back the caller's name and message to confirm accuracy before ending the call; deliver the message promptly after hanging up.
席を外しております' (seki wo hazushite orimasu = away from desk) is the standard polite phrase for 'not available' — it avoids stating exactly where the person went; repeating back the caller's information before hanging up is considered essential professional phone etiquette.
