Summary:                    [patch] Freenum-in-a-can dialplan correction for
failing pattern match
Description: 
Although the existing rule:

exten => _stdexten-.,1,Goto(stdexten-NOANSWER,1)	; Treat anything else as
no answer

will match the extension stdexten-CONGESTION, for instance, a similar
rule:

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

will not.  Apparently in the first instance, 'n' and 'x' are just letters,
but in the second case, 'n' means [1-9].

It's not clear what the difference is.  Adding a workaround.
