Agreed. I tend to use NoOp() for an actual No Operation, such as using it on the
first line of an extension:
exten => something_awesome,1,NoOp()
same => n,Verbose(2,Incoming call from ${CALLERID(all)})
same => n,Dial(SIP/someone_awesome)
same => n,Hangup
That way if you want to place things ahead of any line, you can do that without
impunity. Even using Verbose() on the first line can cause problems if you want
to move the Verbose() around and place something before it -- now you have to do
some copy/pasting, and extra work that could be avoided :)
