Ooma Office supports call waiting on all extensions. When you’re on the phone and another call comes in, an electronic beep will sound to let you know that someone else wants to talk. If your phone is caller-ID capable, the second caller’s caller-ID will appear on the screen.
You can disable call waiting for a single call by dialing [*70] before you dial your number.
Locate your device in the list below for more specific instructions on answering call waiting.
Press the phone’s flash button to put the active call on hold and answer the incoming call.
