This service notifies a subscriber that a second call is on the line and allows the subscriber to switch between the calls.

The called party is notified by a tone when the call is waiting.
The calling party receives an announcement telling them the system has alerted the called party.
When you hear a Call Waiting tone during a call, hit flash-hook to swap between the callers.
If you hang up while a call is still on hold, you will receive a ringback reminding you to reconnect the call.

Note: To disable call waiting for the next call only, press *70 before the call
