The PHONEERR constants consist of a list of error codes that the implementation can return when invoking operations on phone devices. Consult the individual function descriptions to determine which of these error codes each function can return.
The following table shows the PHONEERR constants.
| Value | Description |
|---|---|
|

|
PHONEERR_BADDEVICEID = 0x90000002 |
The specified device identifier is invalid or out of range. |
|
PHONEERR_INCOMPATIBLEAPIVERSION = 0x90000003 |
The application requested an API version or version range that cannot be supported by the TAPI implementation or the corresponding service provider. |
|
PHONEERR_INCOMPATIBLEEXTVERSION = 0x90000004 |
The application requested an extension version or version range that cannot be supported by the service provider. |
|
PHONEERR_INIFILECORRUPT = 0x90000005 |

The button states parameter is invalid. |
|
PHONEERR_INVALDATAID = 0x9000000C |
The specified data identifier is invalid. |
|
PHONEERR_INVALDEVICECLASS = 0x9000000D |

The service provider extension version number is invalid. |
|
PHONEERR_INVALHOOKSWITCHDEV = 0x9000000F |
The hookswitch device parameter is invalid. |
|
PHONEERR_INVALHOOKSWITCHMODE = 0x90000010 |

|
PHONEERR_INVALRINGMODE = 0x90000017 |
The ring mode parameter is invalid. |
|
PHONEERR_NODEVICE = 0x90000018 |

|
PHONEERR_NODRIVER = 0x90000019 |
The telephone service provider for the specified device found that one of its components is missing or corrupt in a way that was not detected at initialization time. The user should be advised to use the Telephony Control Panel to correct the problem. |
|

|
PHONEERR_OPERATIONUNAVAIL = 0x9000001D |
The operation is not available. |
|
PHONEERR_REINIT = 0x90000023 |
If TAPI reinitialization has been requested, for example as a result of adding or removing a telephony service provider, then phoneInitializeExor phoneOpenrequests are rejected with this error until the last application shuts down its usage of the API (using phoneShutdown), at which time the new configuration becomes effective and applications are once again permitted to call phoneInitializeEx. |
|
PHONEERR_REQUESTOVERRUN = 0x90000020 |
The maximum number of outstanding phone requests has been exceeded. |
|
PHONEERR_RESOURCEUNAVAIL = 0x9000001F |

Remarks
The values 0xC0000000 through 0xFFFFFFFF are available for device-specific extensions; the values 0x80000000 through 0xBFFFFFFF are reserved; and 0x00000000 through 0x7FFFFFFF are used as request identifiers.
If an application gets an error return that it does not specifically handle, such as an error defined by a device-specific extension, it should treat the error as an error or type PHONEERR_OPERATIONFAILED. This implies that the error occurred for an unspecified reason
