What is a symbolized call stack?

I have been working on an application(Windows) on Visual Studio 2010 and encountered a crash. So for the same i asked for help from an expert and he asked me to submit a symbolized call stack of crash. Can anyone explain me what exactly is this symbolized call stack and how to get that from VS. The application i am building is using CEF(Chromium embedded framework). I have downloaded binaries and modifying it to my needs.

I think he is asking for a call stack with symbols available (as opposed to just call offsets like this - libcef.dll!11357796() Unknown).

Assuming you are developing with a binary distribution of CEF, go back to https://cefbuilds.com/ and find the distribution you used and the exact build number. At the end of the row you will see an additional link for Debug or Release Symbols. Download these and unzip them if zipped.

Now go back to your Visual Studio project, run until you hit your crash. Double click one of the unresolved symbols like "libcef.dll!11357796() Unknown". You will get a dialog asking you to locate the debug symbol file. Navigate to where you extracted the pdb files in the previous step, and it should find the symbols. It will then try to load the source file, which you don't have unless you downloaded CEF and Chromium sources, but you don't need that for a symbolic stack track. Just cancel and in your call stack you should now see symbols for all of libcef. Copy and paste and pass on to the person helping you.

It's one that has function names (and ideally filenames and line numbers) rather than plain hex addresses.

If you have debug symbols for your build, the call stack you get in the Visual Studio debugger's Call Stack window should be symbolized.
