As I understand it, same => is a way to shorthand your list of the other
keywords. In the example you posted, you save 4 keystrokes for each line you
enter; not a lot of savings for this short example, but put it in a 1000+
line dialplan and it's quite a time-saver.

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
