1 Feature History Release 12.2(11)T Modification This feature was introduced. This document describes the QSIG for TCL IVR (Tool Language Interactive Voice Response) 2.0 feature in and includes the following sections: Feature Overview, page 1 Supported Platforms, page 2 Supported Standards, MIBs, and RFCs, page 3 Prerequisites, page 3 Configuration Tasks, page 4 Configuration Examples, page 6 Reference, page 8 Glossary, page 11 Feature Overview Q.SIG support is required for European countries to interconnect enterprise customers to a wholesale voice solution. The Q.SIG for TCL IVR 2.0 feature provides transparent Q.SIG interworking when using a TCL IVR version 2.0 voice application on a Cisco IOS Voice gateway. This functionality can be enabled using a new CLI on the POTS or VoIP dial-peer. Prior to this feature, Q.SIG messages were interpreted by the TCL IVR 2.0 application, rather than passed transparently to the remote endpoint. Benefits Increases VoIP wholesale providers interconnection options. Increases program efficiency by eliminating unnecessary decoding. 1

2 Supported Platforms QSIG for TCL IVR 2.0 Restrictions Applicable to VoIP and POTS dial peers only. This feature applies to TCL IVR version 2.0 only; not version 1.0.

To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature. Cisco Feature Navigator is a web-based tool that enables you to quickly determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common. 2

3 Supported Standards, MIBs, and RFCs To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank to cco-locksmith@cisco.com. An automatic check will verify that your address is registered with Cisco.com. If the check is successful, account details with a new random password will be ed to you. Qualified users can establish an account on Cisco.com by following the directions found at this URL: Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL: Availability of Cisco IOS Software Images Platform support for particular Cisco IOS software releases is dependent on the availability of the software images for those platforms. Software images for some platforms may be deferred, delayed, or changed without prior notice. For updated information about platform support and availability of software images for each Cisco IOS software release, refer to the online release notes or, if supported, Cisco Feature Navigator.

4 Configuration Tasks QSIG for TCL IVR 2.0 Before you configure your router or access server platform with this feature, complete the following activities: Establish a working IP network. For more information, refer to the Cisco IOS documentation set. See specifically the Cisco IOS IP and IP Routing Configuration Guide, Release 12.1, and the Cisco IOS Voice, Video, and Fax Configuration Guide, Release Configure VoIP. For more information, refer to the Cisco IOS Voice, Video, and Fax Configuration Guide, Release Download the TCL scripts required for this feature, located at the following URL: Ensure that the VCWare version used for the AS5300 is compatible with the IOS image being used. Note VCWare applies only to the Cisco AS5300. Configuration Tasks This command controls the interpretation of supplementary service (QSIG, H.450, and so on) on a gateway. When the CLI is enabled (that is, set to pass through mode), the supplementary service message (usually in Q.931 facility message) is transparently sent to the destination gateway without any interpretation (raw). When the CLI is not enabled (the default), the supplementary service message is decoded and interpreted by the gateway. This CLI is available under VoIP or POTS dial peers. Note This CLI only has effect if a TCL IVR 2.0 application is configured on the same dial peer. The default session application always performs transparent Q.SIG interworking. TCL IVR 1.0 applications always interpret and consume the Q.SIG supplementary services messages. Before starting the software configuration tasks for theivr Version 2.0 features, complete the following pre-installation tasks: Download the TCL Scripts and audio files to be used with this feature from the CCO Software Support Center. Store the TCL scripts and audio files on a TFTP server configured to interact with your gateway access server. Create the IVR/TCL application script to use with the call application voice command when configuring IVR using TCL scripts. You create this application first, store it on a server, or location where it can be retrieved by the access server, then you configure the access server to use IVR with the application that you created. Configure the dial peer on incoming POTS or VoIP dial peers. See the following sections for configuration tasks for the QSIG TCL IVR 2.0 feature.

5 Configuration Tasks Configuring the Application The application that is to be called to interact with the dial peer (that collects the digits from the caller), needs to be created before configuring the dial peer that will call this applicaiton. Use the call application voice command as shown. Each command line is optional depending on the type of action desired, or which digits to collect. Step 1 Router(config)# call application voice application-name location Purpose Defines the name of the applicaiton to be used with your IVR script, and indicates the location of the appropriate IVR script to be used with this application. The location can be a URL, directory, or a TFTP server. Step 2 Router(config-dial-peer)# exit Exits dial-peer configuration mode. Configuring Supplementary Service for POTS Dial-Peer Purpose Step 1 Router(config)# dial-peer voice tag pots Enters voice dial-peer configuration mode. Step 2 Step 3 Router(config-dial-peer)# application application-name Router(config-dial-peer)# tag Digits that define a particular dial peer. Valid entries are from 1 to 2,147,483,647. pots Indicates that this is a plain old telephone service (POTS) peer using VoIP encapsulation on the IP backbone. Specifies the application that will handle incoming voice calls associated with this dial-peer.' Configures supplementary service feature to transparently pass supplementary service to the next gateway. Step 4 Router(config-dial-peer)# exit Exits dial-peer configuration mode. Configuring Supplementary Service for VoIP Dial-Peer Purpose Step 1 Router(config)# dial-peer voice tag voip Enters VoIP dial-peer configuration mode. Step 2 Router(config-dial-peer)# application application-name tag Digits that define a particular dial peer. Valid entries are from 1 to 2,147,483,647. voip Indicates that this is a VoIP peer using voice encapsulation on the POTS network. Specifies the application that will handle incoming voice calls associated with this dial-peer.' 5

To enable interpretation, use the no form of this command. no Syntax Description pass-through Configures the supplementary service feature to transparently pass supplementary service to the next gateway. Defaults The interpretation of supplementary service messages is enabled. Modes Dial-peer configuration History Release 12.2(2)XU Modification This command was introduced. Usage Guidelines When in pass-through mode all ssinfo from the Facility message is discardedby the TCL IVR 2.0 application and the raw message is sent to another leg.when it is turned to non-pass-through mode (default) TCL IVR 2.0 checks the content of ssinfo and sends it to the supplementary service module. Applies only when a TCL IVR 2.0 application is configured on the dial-peer. Examples The following example shows interpretation of supplementary service messages has been disabled.for POTS dial peer 999: dial-peer voice 999 pots application session destination-pattern 4... direct-inward-dial port 1:D Related s application call application voice Description To enable a specific application on a dial peer. For H.323 networks, the application is defined by a TCL IVR filename and location. Creates an application and indicates the location of the corresponding TCL files that implement this application. 9
