A voice mail system is furnished with voiceprint analysis and comparison units. In a first mode, the system discriminates whether the voiceprint of a calling party coincides with a predetermined voiceprint. If the voiceprint of the calling party does coincide with the predetermined voiceprint, the telephone circuit of the calling party is switched and connected to a predetermined telephone circuit. If the voiceprint of the calling party does not so coincide, a message from the calling party is accumulated as voice mail. Therefore, a telephone switching apparatus can be realized whose user can talk with a desired calling party without using a password and which functions as an answer phone when the telephone circuits are not switched. In a second mode, messages from the calling parties are accumulated as voice mail.
