Call Routing / Dial Plans

IOS PSTN Ingress Gateway to CVP (Call Queue and Collect) Call Flow

Document ID: 98614

Updated: Sep 25, 2007

   Print

Introduction

Cisco Customer Voice Portal (CVP) delivers intelligent and interactive voice response (IVR) applications that can be accessed over the phone. There are three types of CVP deployments:

  • Standalone Service

  • CVP Call Control

  • Call Queue and Collect

This document describes the call flow from the perspective of H.323 based IOS® Ingress Gateway in a Call Queue and Collect deployment.

In Call Queue and Collect deployment, the CVP interacts with Intelligent Contact Management (ICM) to make call routing decisions. ICM requests the CVP to provide Voice Response Unit (VRU) treatment to the incoming call for playing menu prompts and collecting digits to determine the skill group to be selected. When the skill group has been identified and an agent from the skill group is available, ICM requests CVP to connect the incoming call to the Agent IP Phone via Cisco CallManager. If the agent is not available, ICM requests CVP to provide call queue treatment (for example play a music-on-hold prompt). CVP provides VRU or call queue treatment by using a VXML Gateway.

Call Flow Example

This section describes the call flow that results from this configuration example:

  1. An ISDN call arrives at the PSTN / VXML Gateway across T1 PRI 1/0/0.

  2. IOS Gateway matches POTS dial-peer 2 as the inbound dial-peer for this call.

  3. IOS Gateway matches VoIP dial-peer 1 as the outbound dial-peer for this call.

  4. IOS Gateway prepends tech-prefix “2#” to the called number and sends an ARQ to Gatekeeper.

  5. Gatekeeper routes the call to CVP.

  6. CVP answers the call and RTP media connection is established between IOS Ingress Gateway and CVP.

  7. CVP informs ICM about the new call.

  8. ICM runs the script associated with the called number of this call.

  9. ICM requests CVP to provide VRU treatment to play a Menu prompt (Main_Welcome_Menu.wav) and to collect digits to identify the skill group.

    1. 1 for TAC

    2. 2 for Sales

    ICM also sends the ICM Label (8001112222) of the Network VRU to CVP.

  10. CVP sends an ARQ request (with destination = Network VRU label) to Gatekeeper.

  11. Gatekeeper provides the IP address of the VXML Gateway in the ACF response.

  12. CVP sends a H225 Setup to VXML Gateway which then establishes a VXML session to CVP. Refer to these URL(s) to understand VXML Gateway and CVP, and VXML Gateway and ASR/TTS server interactions:

  13. CVP disconnects its existing RTP media connection to the Ingress Gateway by sending H245 Empty TCS.

  14. CVP establishes a RTP media connection between Ingress Gateway and VXML Gateway.

  15. PSTN caller enters digit “1” to select the “TAC” skill group. The Ingress Gateway sends the DTMF via RTP NTE to VXML Gateway 16) VXML Gateway reports the digits to CVP via VXML which then reports to ICM.

  16. VXML Gateway reports the digits to CVP via VXML which then reports to ICM.

  17. ICM then finds an available agent from the selected skillgroup and requests CVP to route the call to the Agent by sending the ICM Label (3#75001) of the Agent.

  18. CVP disconnects the existing RTP media connection betweeen the Ingress Gateway and VXML Gateway.

  19. CVP sends an ARQ request (with destination = Agent label) to Gatekeeper.

  20. Gatekeeper provides the IP address of the Cisco CallManager in the ACF response.

  21. CVP sends a H225 setup to Cisco CallManager which then establishes a call to the Agent IP Phone.

  22. CVP establishes a RTP media connection between the Ingress Gateway and Agent Phone.

  23. The PSTN caller hangs up the call after finishing the conversation with the Agent.

  24. Ingress Gateway disconnects the call to CVP and informs the Gatekeeper about call termination.

  25. CVP then disconnects the call to CCM.

Troubleshoot

This section provides information you can use to troubleshoot your configuration.

Troubleshooting Commands

Configure the IOS Gateway to log the debugs in its logging buffer and disable the “logging console”.

These are the commands used to configure the Gateway in order to store the debugs in the Gateway's logging buffer:

  • service timestamps debug datetime msec

  • service sequence

  • no logging console

  • logging buffered 5000000 debug

  • clear log

These are the debug commands used to troubleshoot the configuration:

  35. After finishing the conversation with the Agent, the PSTN caller hangs up the call. Ingress GW receives ISDN Disconnect from the PSTN

  36. Ingress GW terminates the H323 call on the IP leg by sending H225 Release Complete message to CVP

  37. GW sends DisengageRequest (DRQ) to the Gatekeeper

  38. H245 connection between the GW and CVP gets closed after the exchange of CLC and EndSession commands
