Correct Answer:
B. The Post Call Survey DN is called if the Unified CVP has received at least one CONNECT message from CCE (either from the VRU leg or the Agent's leg). Use the END node in the CCE routing script if the Post Call Survey is not required for the calls disconnected from the IVR.; D. The Post Call Survey DN is called if the Unified CVP has received at least one CONNECT message from CCE (either from the VRU leg or the Agent's leg). Use the Release node in the CCE routing script if the Post Call Survey is not required for the calls disconnected from the IVR.
Explanation:
A One of the conditions in which PCS legs get invoked is if Router Re-query is misconfigured and the Ring-No-Answer timeout expires, the caller is still transferred to the Post Call Survey DN. This can occur if a Queue node is used and Enable target re-query is checked, as this causes CVP to send a new routing request to CCE when no agent answers the call. B Another condition in which PCS legs get invoked is if The Post Call Survey DN is called if the Unified CVP has received at least one CONNECT message from CCE (either from the VRU leg or the Agent's leg). Use the END node in the CCE routing script if the Post Call Survey is not required for the calls disconnected from the IVR, as this prevents CVP from transferring the call to the Post Call Survey DN when the call is terminated by the caller or the IVR.
