The first thing to do when researching an unknown number that registers on your Caller ID is to identify whether the area code is local, national, or international. If you don't recognize the area code, you can simply enter that code into a search tool of any of the major search engines. Just type in something along the lines of "area code+country"
Once you find out which country the call came from, you can start the process of doing a reverse phone number lookup. From this point you can try finding out who the number belongs to by going to that country's specific phone directory website. For example, if you have determined that your anonymous phone call originated from Canada, you can try to find out the identifying information behind that number at a Canadian phone directory site.
If the above method falls short, you can try one of the reverse phone number lookup directories for international numbers available online. Some of these sites are free and some are not. You can also try using Google or any of the other major search engines to find people by phone number in foreign countries. What you'll probably find, though, is that the free sites and search engines won't be able to produce the results you are looking for. So, if you still need to find out the owner's information behind that anonymous missed phone call, you'll have to use one of the paid sites to do your search. Fortunately, the cost is minimal and you can get your results almost instantly with one of the few reputable sites available online.
