Abstract
A communication apparatus which is capable of preventing occurrence of events arising from improper connection. A voltage being applied to an interface for connecting a phone is detected, and it is determined whether or not a value of the detected voltage is equal to or greater than a value determined in advance. When it is determined that the value of the detected voltage is equal to or greater than the value determined in advance, a user is notified that there is a possibility of improper connection. When it is determined that the value of the detected voltage is not equal to or greater than the value determined in advance, a power feeding unit starts feeding power to the interface.
