The protocol used by CVP to communicate to VRU PG is GED-155, which stands for Generic External Device Protocol version 155. GED-155 allows CVP to send and receive messages from VRU PG for call control and data exchange.

drfSchedule.xml is one of the XML files that will be backed up when the Disaster Recovery System performs a cluster-level backup, as it contains the information about the backup schedules. E drfSystem.xml is another XML file that will be backed up when the Disaster Recovery System performs a cluster-level backup, as it contains the information about the system components and their dependencies.

Configuring the Survey DN, CT and associate with the Survey routing script is one of the mandatory ICM AW configurations to get the PCS working properly, as it defines the destination and the treatment for the post call survey. B Setting user.microapp.isPostCallSurvey to y after either the label node or the Queue to Skillgroup/PQ node in the initial incoming DN routing script logic is another mandatory ICM AW configuration to get the PCS working properly, as it indicates that the call is eligible for post call survey.

JNDI is designed to be independent of any specific directory service implementation so a variety of directories can be accessed, such as LDAP, NDS, or DNS. E JNDI is an API that provides naming and directory functionality to applications, such as looking up objects by name, binding objects to names, and creating and destroying naming contexts.

VXML Server and Virtual Voice Browser execute the VXML application to provide service to the caller, such as playing prompts, collecting digits, or transferring calls. E VXML Application can be called up via a CCE Routing Script using the Send to VRU Script node, which sends a request to CVP for executing a specific VXML application.

The first thing that should be verified as part of troubleshooting in this scenario is D. Check if the caller DN settings on SPOG has valid PCS DN patterns configured.

According to the Cisco Packaged Contact Center Enterprise Features Guide, Release 12.0 (1), the mapping of a dialed number pattern to a Post Call Survey number enables the Post Call Survey feature for the call1. Therefore, if the caller DN settings on SPOG do not have valid PCS DN patterns configured, the Post Call Survey feature will not be triggered for any of the calls. The other options are not the first thing to verify, because they are either related to the Post Call Survey script or the expanded call variable that controls Post Call Survey, which are not relevant if the PCS DN patterns are not configured correctly.

According to the Cisco Packaged Contact Center Enterprise Features Guide, Release 12.0 (1), a Post Call Survey is triggered by the hang-up event from the last agent1. When the agent hangs up, the call routing script launches a survey script. The value of the expanded call variable user.microapp.isPostCallSurvey controls whether the call is transferred to the Post Call Survey number. If user.microapp.isPostCallSurvey is set to y (the implied default), the call is transferred to the mapped post call survey number. If user.microapp.isPostCallSurvey is set to n, the call ends1.

Therefore, to invoke the Post Call Survey successfully, the routing script logic should direct the call to the Post Call Survey dialed number after the agent disconnects from the caller. The other options are not correct, because they either do not involve an agent interaction or do not set the user.microapp.isPostCallSurvey variable correctly.

When an explicit or implicit Send to VRU node is encountered, a default Label is returned to CVP. This Label, along with a unique correlation ID, is delivered to CVP. The CVP delivers this string via SIP invite to the Virtual Voice Browser (VVB). At this point, the VVB will ask the ICM script for instruction, such as which VXML application to execute. D When an explicit or implicit Send to VRU node is encountered, a default Label is returned to CVP. This Label, along with a unique correlation ID, is delivered to CVP. The CVP delivers this string via SIP invite to the Virtual Voice Browser (VVB). At this point, the comprehensive VVB script will initiate an RTP session between the Ingress Gateway and an allocated VVB, which will play prompts and collect digits from the caller.

A Dialed Number must be mapped within CCE to a Call Type, which in turn points to a scheduled Routing Script. This allows CCE to route calls based on the dialed number and apply different treatments and reports for different call types.
