Introduction

This document describes the configuration of CVP RONA.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

• ICM Script Editor
• CVP Comprehensive Call Flow

Components Used

The information in this document is based on CVP 10.5.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Configuration

CVP RONA configuration example:

Note: In a real life scenario you increase priority (Queue Priority node) for RONA’ed call (Requery Status of 3) to the right from the Queue to Skill Group node.

After the CVP RNATimeout expires, the VRU sends an EventReport w/NoAnswer to the Router:

08:00:21:862 PG1A-pim3 Trace: VRU->PG:EVENT_REPORT(16 bytes):DID=23 SendSeq#=3 EventCode=NoAnswer(3).
08:00:21:862 PG1A-pim3 Trace: ToRouter_ReRouteReq:REROUTE_REQ  RCID=5004 PID=5000 GrpDelKey=0 Reason=3.
08:00:21:706 ra-rtr Trace: (23 24 27 : 0 0) ReRoute: Reason=3 CallState=15..  

RONA timer set when call arrives and canceled when call is answered:

08:00:10:012 PG1A-pim1 Trace: ScheduleAgentTimer: type = agentTImerRingTimeout, seconds = 10, callback = 16787226.
08:00:21:850 PG1A-pim1 Trace: CancelAgentTimer: type = agentTImerRingTimeout.

If RNA goes off:

08:00:19:996 PG1A-pim1 Trace: ProcessRingTimeout: Agent failed to answer alerting line. AgentID=1 DeviceNetworkTargetID=100003 NumAcdCalls: 0.

Deviations

Target Requery disabled, Call Router immediately responds with Release for EventReport w/NoAnswer and CVP hangs up the call:
