Supported CAP Operations Between CCF and IVR

Call Control Framework (CCF) supports CAMEL Application Part (CAP) protocol operations that can be sent to, and received from, an SRF (Specialized Resource Function) such as an IVR (Interactive Voice Response) system.

The following CAP operations are supported:

Note: The CAP1 protocol does not support these operations.

AssistRequestInstructions

CCF supports AssistRequestInstructions operations sent from the IVR. Supported AssistRequestInstructions Parameters lists the parameters used in AssistRequestInstructions operations and indicates whether CCF supports them. Parameters are listed in the order in which they appear in the specification documents.

Table 1. Supported AssistRequestInstructions Parameters
AssistRequestInstructions Parameter	CAP Protocol Version	Supported
correlationID	CAP2, CAP3, CAP4	Yes
iPSSPCapabilities	CAP2, CAP3, CAP4	Yes

PlayAnnouncement

CCF can send a PlayAnnouncement operation to the IVR, instructing it to play the caller a specific announcement. For information about the PlayAnnouncement parameters that CCF supports, see the discussion about supported CAP operations between CCF and the MSC.

Note: The available parameters in PlayAnnouncement operations are the same, irrespective of whether the PlayAnnouncement operation is sent to the MSC or to an IVR.

PromptAndCollectUserInformation

CCF can send a PromptAndCollectUserInfromation operation to the IVR instead of a PlayAnnouncement operation, to allow the IVR to interact with the subscriber and collect information.

For information about the PromptAndCollectUserInformation parameters that CCF supports, see the discussion about supported CAP operations between CCF and the MSC.

Note: The available parameters in PromptAndCollectUserInformation operations are the same, irrespective of whether the operation is sent to the MSC or to an IVR.

ReceivedInformationArg

Following a PromptAndCollectUserInformation operation, the IVR returns the information collected in a ReceivedInformationArg operation. For details of ReceivedInformationArg operation parameters, see the discussion about supported CAP operations between the MSC and CCF.

Note: The available parameters in ReceivedInformationArg operations are the same, irrespective of whether the operation is sent from the MSC or from an IVR.

SpecializedResourceReport

The IVR can send a SpecializedResourceReport operation to CCF in response to a PlayAnnouncement operation for which the announcement completed indication is set. No parameters are sent in SpecializedResourceReport operations.
