The dialplan in extensions.conf is organized into sections, called contexts. Contexts are the basic organizational unit within the dialplan, and as such, they keep different sections of the dialplan independent from each other. You can use contexts to separate out functionality and features, enforce security boundaries between the various parts of our dialplan, as well as to provide different classes of service to groups of users.
Dialplan contexts
The syntax for a context is exactly the same as any other section heading in the configuration files, as explained in Sections and Settings. Simply place the context name in square brackets. For example, here we define an example context called 'users'.
Introduction to Asterisk Asterisk is a fully Open Source, hybrid TDM and packet voice PBX and IVR platform. Asterisk is and has been Open Source under GNU GPL (with an exception permitted for linking with the OpenH323 project, in order to provide H.323 support). • Asterisk is a hybrid TDM and packet voice PBX • Interfaces any piece of telephony hardware or software to any application • Prime components: channels and extensions.conf - the Asterisk dial plan • Channels can be many different technologies - SIP, IAX, H323, skinny, Zaptel, and others as they are created • extensions.conf is basically a.

You can change asterisk to be the name of your database.
Dialplan extensions
Within each context, we can define one or more extensions. An extension is simply a named set of actions. Asterisk will perform each action, in sequence, when that extension number is dialed. The syntax for an extension is:
Let's look at an example extension.
In this case, the extension number is 6001, the priority number is 1, the application is Dial(), and the two parameters to the application are PJSIP/demo-alice and 20.
Dialplan priorities
Within each extension, there must be one or more priorities. A priority is simply a sequence number. The first priority on an extension is executed first. When it finishes, the second priority is executed, and so forth.

Priority numbers
Priority numbers must begin with 1, and must increment sequentially. If Asterisk can't find the next priority number, it will terminate the call. We call this auto-fallthrough. Consider the example below:
In this case, Asterisk would execute priorities one and two, but would then terminate the call, because it couldn't find priority number three.
Priority letter n
Priority numbers can also be simplified by using the letter n in place of the priority numbers greater than one. The letter n stands for next, and when Asterisk sees priority n it replaces it in memory with the previous priority number plus one. Note that you must still explicitly declare priority number one.
One Or More Adobe Pdf Extensions Are DisabledIcon
Every time an extension and priority is executed Asterisk searches for the next best match in priority sequence.
Consider the dialplan below.
It may not be immediately intuitive, but the '_.!' extension with the 'n' priority will be executed after any of the preceding lines are executed.
Application calls
You'll notice that each priority is calling a dialplan application (such as NoOp, or Verbose in the example above). That is how we tell Asterisk to 'do something' with the channel that is executing dialplan. See the Applications section for more detail.
Priority labels
You can also assign a label (or alias) to a particular priority number by placing the label in parentheses directly after the priority number, as shown below. Labels make it easier to jump back to a particular location within the extension at a later time.
Here, we've assigned a label named repeat to the second priority.
Included in the Asterisk 1.6.2 branch (and later) there is a way to avoid having to repeat the extension name/number or pattern using the same => prefix.
The order of matching within a context is always exact extensions, pattern match extensions, include statements, and switch statements. Includes are always processed depth-first. So for example, if you would like a switch 'A' to match before context 'B', simply put switch 'A' in an included context 'C', where 'C' is included in your original context before 'B'.
Search order:
Make sure to see the Pattern Matching page for a description of pattern matching order.

I've done an
ls -l inside a directory, and my files are displaying like this :
What does that asterisk mean?
I'm also unable to run a particular file, as follows:

Ignacio Vazquez-Abrams has already explained about the

It means that the file is executable. A classifier is shown when -F is passed to ls via the command line or otherwise.
As for the executable-looking
emulator that you can't actually execute, this can happen when the dynamic loader requested by emulator doesn't exist. You can check what kind of file emulator is with the command file emulator , and check what dynamic loader and libraries it needs with ldd emulator (any line showing “not found” is something you need to install).
Given the name of the directory and the size of the file,
emulator is probably a Linux x86 binary. I suspect you have an amd64 system. If so, you need to install a runtime environment for 32-bit applications; on Ubuntu, you need the ia32-libs package (and perhaps also ia32-libs-gtk ).
You could also get this error message for a script whose interpreter as indicated in the
#! line doesn't exist.

Ubuntu (12.04, and probably other versions as well) includes the following setting by default:
And as others have explained,
-F is responsible for the asterisk.
IPython automatically uses the
F flag under the hood (by default), so just entering ls will produce the effect you're seeing there.

Edit: by the way, you are stating you're running
ls -l , running ll may not be the same at all.

As several others have mentioned, the
-F option to ls will flag executables with the asterisk. You don't have a -F in your command line, but it is likely that ls has been aliased. You can check for aliases in your shell of choice (in bash, use the built-in command alias to list the aliases), or escape the ls command with a backslash to disable aliasing.
