The Call Log can be reached by tapping on the phone icon in the bottom menu. You will be presented with a list of your latest entries of outgoing, incoming and missed calls. (Note that this list only contains Totalview calls, and not the local phone log)
If the person is a Totalview contact, the coloured line on the left indicates the state of the corresponding contact, and his name and telephone number are shown. If the person is not to be found in Totalview, only the telephone number is visible. If the name of an entry is coloured in red, it indicates a missed call from that person.
On the right side of an entry, you can see the date and time of the call. Additionally, you can see if it is an outgoing or incoming call, as outgoing calls will feature a little phone icon next to the time. If the person is a Totalview contact, you can open his contact details by clicking on the arrow next to it.
