Why can’t the extension make outbound calls (to landline or cell phones)?
Step 1: Please make sure that the connection of MyPBX and the telecom lines is ok, and check if the lines are available (log in MyPBX Web Configuration Panel and select “Status Monitor”->”Line status”)
Step 2: If the trunk is available to use, please check the configuration of outbound routes (Select “Basic”->”outbound routes”)
