Using the blue handset button at the bottom of the screen 

You can navigate to the dial screen.

Using the keypad, you can enter an external or internal telephone number.

Sometimes, you may see the call key greyed out.

This means there is no connection to our voice servers. Please check your internet connection and try again.

Once you have a solid green handset key, you can now make calls.

If you have made any mistakes when entering your number, you can delete the number by using the X arrow key.

 If you have incorrectly entered a number in the middle of the dial screen, you can click on the number to correct just that number.

Use the X arrow to remove the number.

Put the correct digit in and then press the tick at the end of the number to save the corrected number.

Whilst you are in a call, any buttons that are in a solid state can be used to perform different functions.

Pressing the Hold key will place the other party on hold.

The hold button will then become a resume key.

Pressing the resume will enable the holding call again.

You can also press the mute key to disable your microphone.

Pressing it again will enable your microphone again.
