 Hi:
 When should we use unnumbered priorities(n) in extensions.What is
 the different between these 2 forms of extensions.conf? and ,Are both
 true?
 extensions.conf:
 form1:
 [Conferencerooms]
 exten = 333,1,Answer
 exten = 333,n,meetme(8000|cim)
 exten = 333,n,playback(vm-goodbye)
 exten = 333,n,hangup
 
 form2:
 [Conferencerooms]
 exten = 333,1,Answer
 exten = 333,2,meetme(8000|cim)
 exten = 333,3,playback(vm-goodbye)
 exten = 333,4,hangup

On one of my Asterisk 1.2 setups, I have a dialplan that mixes both - so
they can coexist in the same extensions.conf.

The difference is that with the n type extensions, you can easily
insert a line or three without renumbering lots of lines - and searching
for all those GOTOs that also need a new line number. Renumbering
error-prone.

An advantage of numbering is that the line order is not important,
because of course Asterisk would select by number, not order - and
possibly (although I did not investigate this) including _parts_ of an
extension from another context might work better.

All my new extensions use the n style, but I am not going to rewrite
the older parts of the dialplan soon.

In fact the 'n' is just a shortcut for next number and is translated into
an actual number when the extensions.conf file is read.

If you do show dialplan, you will see all the extensions have numbers,
even if you had used 'n'.
