[asterisk-users] AMI and ExtensionState command returning bogus 'status' number

[Jose P. Espinal]

Hello List,

I have been working on a PHP application in order to build a BLF style 
script.

Until now everything is going Ok but something a little (in my oppinion) 
strange is going on with the 'ExtensionState' command;
The problem is that it does not returns the 'Status' as it's suposed to, 
mentioned in the A.T.F.O.T book - version 2.,
where it sais something like:

"Notes: The following are the possible extension states:
-2  Extension removed
-1  Extension hint not found
0   Idle
1  In use
2  Busy"

I have confirmed that it is returning the 'Status' as described in 
'devicestate.h'
( http://www.asterisk.org/doxygen/1.4/devicestate_8h-source.html ) , 
part of Asterisk source files.

Something like this:

/**
 * Device is valid but channel didn't know state
 * AST_DEVICE_UNKNOWN 0
 *
 * Device is not used
 * AST_DEVICE_NOT_INUSE  1
 *
 * Device is in use
 * AST_DEVICE_INUSE   2
 *
 * Device is busy
 * AST_DEVICE_BUSY    3
 *
 * Device is invalid
 * AST_DEVICE_INVALID 4
 *
 * Device is unavailable
 * AST_DEVICE_UNAVAILABLE   5
 *
 * Device is ringing
 * AST_DEVICE_RINGING 6
 *
 * Device is ringing *and* in use
 * AST_DEVICE_RINGINUSE  7
 *
 * Device is on hold
 * AST_DEVICE_ONHOLD  8
 *
*/


Am I missing something?
Is this a 'bug' or I just blew something?
May I safely base my application on the 'Status' numbers returned as 
described in 'devicestate.h'?
Can someone point me to some documentation that can clarify this?


Thank you in advice,
Regars.
