Caller ID
When the telephone rings, the Cisco ATA sends a Caller ID signal to the telephone between the first and
second ring (with name, telephone number, time, and date information, if these are available).
Call-Waiting Caller ID
The Cisco ATA plays a call waiting tone, then sends an off-hook Caller ID signal to the telephone
immediately after the first tone burst.
The Cisco ATA sends the name, telephone number, time, and date information, if these are available.
Voice Mail Indication
This feature allows the Cisco ATA to play an intermittent dial tone if there is a message in the user's voice
mail box.
