Description
This parameter enables or disables entry tone generation for the telephony interface. If entry tones are
enabled (1), then an entry tone is played whenever the auto-answer feature engages and connects the
telephony interface. Entry tones and exit tones (see the phone_exit_tone_en parameter) are typically
enabled to prevent a caller from entering or exiting a conference unannounced.
