[asterisk-users] Issue with (pattern) matching extension

[Philip A. Prindeville]

Here's a segment of my dialplan, I'm working on the freenum/ISN
functionality:


same => n,Set(isnresult=${ENUMLOOKUP(${EXTEN},sip,,1,freenum.org)})
same => n,GotoIf($["${isnresult}" != ""]?:fn-CONGESTION,1)
; set up our outgoing call state
same => n,Set(SIPFROMUSER=${CALLERID(num)})
same => n,GotoIf($["${GLOBAL(FREENUMDOMAIN)}" == ""]?dial:)
same => n,Set(SIPFROMDOMAIN=${GLOBAL(FREENUMDOMAIN)})
same => n(dial),Dial(SIP/${isnresult},40)
same => n,Goto(fn-${DIALSTATUS},1)

exten => fn-BUSY,1,Busy()

exten => _fn-.,1,NoOp(ISN: ${DIALSTATUS})
same => n,Congestion()


and the logging:



  == ast_get_enum(num='555*99999', tech='sip', suffix='freenum.org', options='', record=1
  == ENUM options(): pos=1, options='2'
  == ISN ENUM: left=555, middle='99999.'

pbx*CLI> 


Note that the string "fn-CONGESTION" isn't matching the extension pattern:

exten => _fn-.,1,NoOp(ISN: ${DIALSTATUS})

and I'm not sure why.

Anyone want to venture how to go about figuring out how?
