Call Waiting Usage
When you're on the phone and another call comes in, you will hear a Call Waiting tone. Hit flash/hook to swap between the callers. If you hang up while a call is still on hold, you will receive a ring back reminding you to reconnect the call.
To Temporarily Disable Call Waiting
You can disable call waiting on a per-call basis to prevent a specific call from being interrupted.
Lift the receiver and listen for the dial tone.
Dial *70 + the number you wish to call.
Call waiting is disabled for the current call only.
Inbound calls will be directed to your voicemail.
