That's not true.

Here's a short snippet of some of my code to show you the return
values:

---cut---
# These states are used in the manager API (since 1.4?) (see
# action_extensionstate() in manager.c, enum ast_extension_states in
# pbx.h, ast_extension_state() and ast_extension_state2() in pbx.c).
# They are different from the device states (AST_DEVICE_...)!
#
define( 'AST_MGR_EXT_UNKNOWN'  ,        -1  );  # no hint for the extension
define( 'AST_MGR_EXT_IDLE'     ,         0  );  # all devices idle (but registered)
define( 'AST_MGR_EXT_INUSE'    , 1<<0 /* 1*/);  # one or more devices busy
define( 'AST_MGR_EXT_BUSY'     , 1<<1 /* 2*/);  # all devices busy
define( 'AST_MGR_EXT_OFFLINE'  , 1<<2 /* 4*/);  # all devices unreachable/not registered
define( 'AST_MGR_EXT_RINGING'  , 1<<3 /* 8*/);  # one or more devices ringing
define( 'AST_MGR_EXT_ONHOLD'   , 1<<4 /*16*/);  # all devices on hold

define( 'AST_MGR_EXT_RINGINUSE', AST_MGR_EXT_INUSE |  # one or more devices busy
                                 AST_MGR_EXT_RINGING  # and one or more devices
                                      /* 9*/);        # ringing
---cut---

(The code is GNU/GPL but I'm sure you can learn from it and write
your own should the license be incompatible to yours.)
