The Wiki is (always) out of date. You might consider taking a look at http://www.asteriskdocs.org/en/3rd_Edition/asterisk-book-html/asterisk-book.html#DialplanBasics_id262049 which is likely less out of data.

It is self explanatory, for example:
exten => _X.,1, Noop("Let say we have allowed all numbers i.e. _X means and . specifies any range")
same => n,NoOp("Here we have skipped mentioning dial-pattern again and thats it")
Hope I have answered your question.
Not for me.
What part of those lines and comments discusses "same"?
What is the syntax for a "same" line? what does it mean to use "same" rather than "exten"?

Hello
I have been reading the sample extension.conf
;#######################
[outbound-freenum2]
; This is the handler which performs the dialing logic. It is called
; from the [outbound-freenum] context
;
exten => _X!,1,Verbose(2,Performing ISN lookup for ${EXTEN})
same => n,Set(SUFFIX=${CUT(EXTEN,*,2-)}) ; make sure the suffix is all digits as well
same => n,GotoIf($["${FILTER(0-9,${SUFFIX})}" != "${SUFFIX}"]?fn-CONGESTION,1)
; filter out bad characters per the README-SERIOUSLY.best-practices.txt document
same => n,Set(TIMEOUT(absolute)=10800)
same => n,Set(isnresult=${ENUMLOOKUP(${EXTEN},sip,,1,freenum.org)}) ; perform our lookup with freenum.org
same => n,GotoIf($["${isnresult}" != ""]?from)
same => n,Set(DIALSTATUS=CONGESTION)
same => n,Goto(fn-CONGESTION,1)
same => n(from),Set(__SIPFROMUSER=${CALLERID(num)})
same => n,GotoIf($["${GLOBAL(FREENUMDOMAIN)}" = ""]?dial) ; check if we set the FREENUMDOMAIN global variable in [global]
same => n,Set(__SIPFROMDOMAIN=${GLOBAL(FREENUMDOMAIN)}) ; if we did set it, then we'll use it for our outbound dialing domain
same => n(dial),Dial(SIP/${isnresult},40)
same => n,Goto(fn-${DIALSTATUS},1)
exten => fn-BUSY,1,Busy()
exten => _f[n]-.,1,NoOp(ISN: ${DIALSTATUS})
same => n,Congestion()
;##########################
According to "http://www.voip-info.org/wiki/view/Asterisk+config+extensions.conf"
"Syntax for defining a context: keywords exten, include, ignorepat and switch." "same is not mentioned in this wiki."
There is a part of dial plan from sample extension.conf above. My Question is how "same =>" key word works .
Thanks
