Configuring the Cisco Router with IVR

Revised June 30, 2011

A Cisco gateway router provides integrated voice response (IVR) functionality to the Cisco TelePresence Exchange System, thus providing greetings and voice prompts to conference participants.

This section describes the configuration that is required on the Cisco gateway router to provide IVR functionality, and includes the following topics:

•Downloading Application Files from the FTP Server

•Configuring the Router to Pass SIP Headers

•Configuring Application Parameters

•Configuring VOIP Dial Peers

For supported router models and Cisco IOS software requirements, see the applicable Release Notes for Cisco TelePresence Exchange System, at http://www.cisco.com/go/ctx-relnotes.

For additional details about configuring SIP, see the Cisco IOS SIP Configuration Guide, Release 12.4T, at http://www.cisco.com/en/US/docs/ios/voice/sip/configuration/guide/12_4t/sip_12_4t_book.html.

Downloading Application Files from the FTP Server

To download the Meet-Me application file from the Cisco FTP Server, do the following procedure: 

Router # copy ftp:// <user>:<password>@<host>/<path_to_file> flash:

where

User is the login username for the FTP server on which you download the meetme-tcl file.

Password is the login password for the FTP server.

Host is the hostname or IP address of the FTP server.

Path_to_file is the full path to the meetme.tcl file on the home directory of the FTP server.

Flash is the local directory in which the system copies the file.

Configuring the Router to Pass SIP Headers

Procedure

To configure the router to pass the SIP headers to the VXML application, do the following procedure:

 
Command
Purpose

Step 1  

Router(config)# voice service 
voip

Enters voice service configuration mode for VoIP.

Step 2  

Router(config-voi-srv)# sip

Enters Session Initiation Protocol (SIP) configuration mode.

Step 3  

Router(config-serv-sip)# 
header-passing

Enables passing of headers in the SIP INVITE, SUBSCRIBE, and NOTIFY messages.

Step 4  

Router(config-serv-sip) exit

Exits SIP configuration mode.

The following example configures the IVR service to pass the message headers: 

Router(config)# voice service voip

Router(config)# sip

Router(config)# header-passing

Configuring Application Parameters

Procedure

To configure an application on the router, do the following procedure:

 
Command
Purpose

Step 1  

Router(config)# application

Enters application configuration mode.

Step 2  

Router(config-app)# service 
application-name location

Configures a specific application on a dial peer. Location is the directory and file name of the Tcl script for the application.

Step 3  

Router(config-app)# monitor

Enters monitor configuration mode.

Step 4  

Router(config-app-monitor)# 
interface stats

Enables statistics monitoring for the interface.

Step 5  

Router(config-app-monitor)# 
interface event-log

Enables event logging for the interface.

Step 6  

Router(config-app-monitor) 
stats

Enables statistics collection.

Step 7  

Router(config-app-monitor)# 
event-log

Enables event logging for the voice application.

The following example configures the Meet-Me service: 

Router(config)# application

Router(config-app)# service meet_me flash://meetme.tcl

Router(config-app)# monitor

Router(config-app-monitor)# interface stats

Router(config-app-monitor)# interface event-log

Router(config-app-monitor)# stats

Router(config-app-monitor)# event-log

Configuring VOIP Dial Peers

Procedure

To define a dial peer, do the following procedure:

 
Command
Purpose

Step 1  

Router(config)# dial-peer 
voice tag voip

Defines a VoIP dial peer. Tag is a locally unique number.

Step 2  

Router(config-dial-peer)# 
application application-name

Specifies the application for the dial peer.

Step 3  

Router(config-dial-peer)# 
session protocol sipv2

Specifies a session protocol for use between the peers.

Step 4  

Router(config-dial-peer)# 
incoming called-number string

Configures the expected digit string for incoming called numbers.

Step 5  

Router(config-dial-peer)# 
dtmf-relay rtp-nte sip-kpml

Specifies how to relay dual-tone multi-frequency (DTMF) tones to the peer.

The rtp-nte keyword tells the router to forward DTMF tones by using the real-time protocol (RTP) with the Named Telephone Event (NTE) payload type.

The sip-kpml keyword tells the router to forward DTMF tones through Keypad Markup Language (KPML) messages.

Step 6  

Router(config-dial-peer)# 
codec codec

Specifies the voice codec rate of speech for a dial peer.

The following example configures the VoIP dial peer for the Meet-Me service: 

Router(config)# dial-peer voice 100 voip

Router(config-dial-peer)# service meet_me

Router(config-dial-peer)# session protocol sipv2

Router(config-dial-peer)# incoming called-number 3666

Router(config-dial-peer)# dtmf-relay rtp-nte

Router(config-dial-peer)# codec g711ulaw
