Description of SwitchKit negative responses
A Dialogic® SwitchKit® Development Environment (SwitchKit) API message sent to a Dialogic® Converged Services Platform (CSP) or a Dialogic® Multi-Services Platform (MSP) should receive a response indicating either an 0x10 for a positive status or another response.
For a CSP a list of responses can be found
here.
For an MSP a list of responses can be found in the API reference found on
this page by selecting 'response status values'.
These lists do not include Dialogic® SwitchKit® Development Environment (SwitchKit) negative responses (NACKs). SwitchKit NACKS are different from other negative responses in that they are not initiated by the switch, but by the LLC process communicating with the switch. They are used for a number of purposes, but the main two are to indicate that the switch did not respond to a message (SK_NO_ACK_FROM_SWITCH 0xf009) or that the message sent was either not formatted correctly or was corrupted due to network issues (SK_BAD_MESSAGE 0xf007). You will also see SK_BAD_MESSAGE if you send a message to a non-existent node ID.
This is a list of SwitchKit responses:
SK_BAD_PARAM 0xf002: This response is seen when sending a SwitchKit message with some sort of bad parameter for example sending sk_configChannelGroup with an inconfig hunting parameter.
SK_CANCELED 0xf003: This response is seen when a message is cancelled. Typically only seen when sending SKC_CancelUserTimer
SK_MTX_ACTIVE 0xf004: This response is seen when sending ActivateMatrix() to an already active matrix/CPU card
SK_OOS_OUTSEIZE 0xf005: This response is seen when sending an SKC_OutseizeControl Message to an out of service channel
SK_BAD_APP_NAME 0xf006: This response is seen when using inter-application messaging and sending a message to a non-existant application name
SK_BAD_MESSAGE 0xf007: This response is seen when the message initially sent is formatted incorrectly or the node that message was sent to was either unreachable or does not exist.
SK_NO_SEQNUMS 0xf008: This message is seen when the CSP or MSP runs out of sequence numbers and can not respond to a message
SK_NO_ACK_FROM_SWITCH 0xf009: This message is seen when no response is seen from the switch or if the response was lost due to network issues.
SK_BAD_ENGINE_NAME 0xf00a: This message should not be seen, but if it does, it indicates a problem with the connection between SwitchKit and the application sending the message
SK_SWITCHBACK_FAILED 0xf00b: This message is seen when running redundant SwitchKit hosts and the switch back to active does not occur successfully
These responses are also documented in SK_API.h.
