Thanks, but I think device states are different from extension states.
(Please correct me If I'm mistaken.)
Device states from devicestate.h:
---cut---
/*! Device is valid but channel didn't know state */
#define AST_DEVICE_UNKNOWN 0
/*! Device is not used */
#define AST_DEVICE_NOT_INUSE 1
/*! Device is in use */
#define AST_DEVICE_INUSE 2
/*! Device is busy */
#define AST_DEVICE_BUSY 3
/*! Device is invalid */
#define AST_DEVICE_INVALID 4
/*! Device is unavailable */
#define AST_DEVICE_UNAVAILABLE 5
/*! Device is ringing */
#define AST_DEVICE_RINGING 6
/*! Device is ringing *and* in use */
#define AST_DEVICE_RINGINUSE 7
/*! Device is on hold */
#define AST_DEVICE_ONHOLD 8
---cut---
I was looking for the extension states as sent by the manager interface.
Extension states from pbx.h:
---cut---
/*! \brief Extension states */
enum ast_extension_states {
AST_EXTENSION_REMOVED = -2, /*!< Extension removed */
AST_EXTENSION_DEACTIVATED = -1, /*!< Extension hint removed */
AST_EXTENSION_NOT_INUSE = 0, /*!< No device INUSE or BUSY */
AST_EXTENSION_INUSE = 1 << 0, /*!< One or more devices INUSE */
AST_EXTENSION_BUSY = 1 << 1, /*!< All devices BUSY */
AST_EXTENSION_UNAVAILABLE = 1 << 2, /*!< All devices
UNAVAILABLE/UNREGISTERED */
AST_EXTENSION_RINGING = 1 << 3, /*!< All devices RINGING */
AST_EXTENSION_ONHOLD = 1 << 4, /*!< All devices ONHOLD */
};
---cut---
1<<4 == 16, so probably this is the value I observed.
But there some mangling occurs in ast_extension_state2() in pbx.c like
if (inuse && ring)
return (AST_EXTENSION_INUSE | AST_EXTENSION_RINGING);
which would return
1<<0 | 1<<3 == 1|8 == 9
So the extension state is some kind of a bit mask.
I think I have found what I was looking for. :)
Thanks,
Philipp Kempgen
