[Synopsis]:
Provide directory of voicemail extensions

[Description]:
  Directory(vm-context[|dial-context[|options]]): Presents the user with a directory
of extensions from which they  may  select  by name. The  list  of  names 
and  extensions  is discovered from  voicemail.conf. The  vm-context  argument
is required, and specifies  the  context  of voicemail.conf to use.  The
dial-context is the context to use for dialing the users, and defaults to
the vm-context if unspecified. The 'f' option causes the directory to match
based on the first name in voicemail.conf instead of the last name.
Returns 0 unless the user hangs up. It  also sets up the channel on exit
to enter the extension the user selected.
