1. To make an outbound call, you must enter the number in the international dialing format into the dial pad otherwise the call will not get connected.
(International format is + or 00 followed by the country code then the number. For example, If I want to make a call to UAE, you need to enter this format: +971XXXXXXXXX).
2. Another way to make an outbound call is done as follows:
Go to the “Recent Calls” section found on the left hand side of the dial pad.
Place the mouse over any number, a green “Call Again” button appears.
Click on the green button and the call will start ringing.
