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 receiver 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 Cisco ATA can call an additional person, that new person can then call someone else, and so on. This is known as daisy-chaining.

Making a Conference Call in Sweden

Procedure

Step 1 Dial the first number.

Step 2 When the person you called answers, press the flash or receiver button on the telephone handset. This will put the first person you called on hold and a dial tone will sound.

Step 3 Dial the second person and speak normally when that person answers.

Step 4 Perform a hookflash, then press 2 on your telephone keypad to return to the first person. You can continue to switch back and forth between the two callers.

Step 5 To conference with both callers at the same time, perform a hookflash, then press 3 on the telephone keypad. Once you conference all three callers, the only way to drop a caller is for that caller to hang up.

Step 6 (Optional) To conference in additional callers, the last person called with a Cisco ATA can call an additional person, that new person can call someone else, and so on. This is known as "daisy-chaining."

Call Waiting in the United States

If someone calls you while you are speaking on the telephone, you can answer by performing a hook flash. You cannot conference in all three callers, but the first person you called could call someone else and daisy-chain them into the conference.

When the Cisco ATA is configured to use Call Waiting by default, press *70 on your telephone keypad to disable Call Waiting for the duration of the next call.

Call Waiting in Sweden

If someone calls you while you are speaking on the telephone, you can answer by performing a hookflash then pressing 2 on your telephone keypad, or you can conference them with the person to whom you are already speaking by performing a hookflash then pressing 3. You can also perform a hookflash then press 3 later during the call to create a conference call.

Performing a hookflash then pressing 1 hangs up the first caller and answers the second call. If there is no answer after one minute, the caller receives three beeps and a busy signal.

To enable call waiting for Sweden, press *43#. When the Cisco ATA is configured to use Call Waiting by default, press #43# to disable Call Waiting for the duration of the next call.
