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.
Making a Conference Call in the United States
Procedure
Step 1 Dial the first number.
Step 2 When the person you called answers, press the flash or rece iver button on the telephone handset. This
will put the first person you called on hold and you will receive a dial tone.
Step 3 Dial the second person and speak normally when that person answers.
Step 4 To conference with both callers at the same time, perform a hook flash.
Step 5 To drop the second call, perform a hook flash.
Step 6 (Optional) To conference in additional callers, the last person called with a CiscoATA can call an
additional person, that new person can then call someone else, and so on. This is known as
daisy-chaining.
