i have tried to redefine [macro-trunkdial-failover-0.3] in extensions_custom.conf
And no matter what i do while i trying to change one line - it's not used.
Only if i delete nearly all content from it leaving first and last string
exten = s,1,NOOP(MY do call out)
exten = h,1,NOOP(MY no thing to do)
i see it is used but surely not working.
Is there some fuzzy logic when custom is used?
