In 1.2 we switched from priority jumping to returning values in
STATUS variables. If you look in the sample extensions.conf you
will see how that work, that the result of dial() is now returned in
the DIALSTATUS variable.

Using DIALSTATUS will give you many more ways to control the
result of dial, than just checking for +101. You can react to no answer,
congestion, busy, privacy and other things.

Even more detailed status is frequently available in the HANGUPCAUSE
variable that uses ISDN cause codes.

"Show application dial" is your best friend.

For each application that used to return priority+101 or something else
there's a new XXXXSTATUS variable that you can use.

We do no longer accept patches that use priority jumping, that's
a remain from the past that will be removed in future versions of
Asterisk. From the file UPGRADE.txt in the svn trunk distribution:

"Applications:

* In previous Asterisk releases, many applications would jump to  
priority n+101
   to indicate some kind of status or error condition.  This  
functionality was
   marked deprecated in Asterisk 1.2.  An option to disable it was  
provided with
   the default value set to 'on'.  The default value for the global  
priority
   jumping option is now 'off'."
