Put one caller on hold when you receive another call
Second Line is a call waiting service that lets you put one caller on hold when you receive another call. You may speak to the second caller without terminating the first call. An audible notification alerts you when you receive an incoming call if you are already speaking to someone on the phone. With this convenient service, you will never miss another call again.
The Second Line call waiting service is provided free of cost and activated by default for all subscribers.
To deactivate the service, dial #43#YES. To activate the service again, dial *43#YES.
You may also activate or deactivate the service from the phone menu directly.
