CallError Enumeration

Member name	Value	Description
Success	0	Operation completed successfully. This return code is not used.
InProgress	1	Operation has failed because another call operation is in progress.
Failed	2	Operation has failed. The failure reason was not specified.
Rejected	3	Reported when the request is rejected by the server due to a permission error. For example, a call operation is requested on a call that the server believes cannot be supported at this time, e.g., due to call state mismatch. Similarly, a conference moderator operation may be rejected by the server if the local user performing the operation is not a moderator.
Busy	4	Reported when the request is rejected by the server due to resource being busy. For example, a point-to-point call may fail if the called party returns a busy indication, or if there are no local line appearances available on the server side to initiate the call.
CodecMismatch	5	Reported when a VoIP session cannot be established due to incompatible codecs between the local and remote parties.
UserNotFound	6	Reported when the called party address is not known to the server. For example, if user dials an invalid telephone number, this error code is reported.
UserTemporarilyUnavailable	7	Reported when the called party has no device registered on his/her behalf, making call setup not possible at this point in time.
Redirected	8	Operation was redirected to another destination.
Timeout	9	Reported when the send of a network message timed out locally, or a response to the message was not received from the server in time.
SendError	10	Reported when a network message could not be sent due to a network connection error.
AuthenticationFailure	11	Reported when local user's authentication with the network has failed. This can happen when user-supplied credentials do not match the credentials the server expects to receive from the end user.
ServerError	12	Reported when the request has failed due to an internal server error.
StateMismatch	13	Reported when the request cannot be supported at this time due to the current state of the call. For example, a hold request while the call is being transferred is not allowed.
InvalidParameter	14	Reported when an invalid parameter is used for the request. For example, if the application tries to add a participant but provides an empty participant address, this error is reported.
TransportError	15	Reported when request could not be sent to the network server.
LineReservationFailure	16	Reported when a line reservation attempt is failed by the server. It should be noted that line appearance ID and line appearance owner are required to reserve a line appearance when the a call is initiated on a bridged line appearance. If for some reason, the line reservation request fails, this error code is reported. This error code is only applicable to communication systems environments where bridging and bridged line appearances are supported.
RemoteCallNotAlerting	17	Reported when an attempt to locally answer an incoming call at a remote extension (e.g., at a bridged line appearance extension) has failed because the call was already answered remotely.
InternalError	18	Reported when an invalid parameter is used for the request. For example, if the application tries to add a participant but provides an empty participant address, this error is reported.
NoAvailableCallAppearance	19	Reported when the local user's call initiation attempt fails because the Avaya Communication Manager has no idle line appearance available for the call.
NotFound	20	Reported when a conference control operation has failed because the server did not recognize the conference call address.
NotRegistered	21	Reported when an operation fails because the server believes the user is not registered.

MediaStartFailure	24	Reported when local audio and/or video resources cannot be started successfully.
RemoteMediaProcessingFailure	25	Reported when the application tries to accept an incoming call, but this attempt fails because the remote audio and/or video information could not be applied to local audio/video resources.

CellularCallInProgress	27	Reported when a local VoIP/video call creation has failed because of an on-going cellular call.
NotLicensed	28	Reported when an operation is denied because user does not have the license to perform the operation. For example, video add request may be denied using this error code when the user's account is not licensed to support video calls.
NotAuthorized	29	Reported when participant add or remove operations cannot be supported because local user does not have moderator privileges to perform these actions.
WifiUnavailable	30	Reported when a VoIP/video call cannot be set up because there is no Wifi network available to initiate a call and the local policy restricts VoIP/video calls to Wifi networks only.
ConferenceAddressNotValid	31	Reported when an ad-hoc conference creation attempt fails because the provisioned network address used for ad-hoc conference creation is not valid.
