9386, Funny Prompts
Open the dialplan main file with a text editor, and search for "9386".
You'll find it toward the end of the file. We see the "condition" is to exactly match the "destination_number" with "9386", no prefixes, no trailing digits (caret is beginning of string, dollar is end of string). If the destination_number (it is a variable in "caller profile", so we can use it in condition's "field" without the ${} syntax) of the incoming call matches 9386, FreeSWITCH will answer the call (eg, go off hook and begin the media streams packet exchange), sleep for a second and half, then play to the caller an entity called "phrase:funny_prompts" (we'll see later in the book that a "phrase" is a named collection of sound files). After all the playing, if the caller has not already closed the call, FreeSWITCH will hangup.
(Last line in the picture means that all files with an xml extension that are contained in the subdirectory "default" will be read in and "added" to the main dialplan. This is handy for organization, we'll see).
So, this is the first call to our freshly installed FreeSWITCH, let's call 9386 from one of our registered phones, and listen to a series of funny prompts played to us one after another.
