I have several numbers for people who work at the same organisation in my contacts. For this organisation, one rings a main number and after a pause (shows as a comma in the number) their 6-digit extension is fired down the line and one gets connected. All well and good - except the call log seems to show some other random name of people at that organisation! I've only run one of the numbers and have seen two other names in the call log. This didn't happen with my old Samsung Galaxy Y which is also android.
