Provisioning the Supplementary Services Gateway Preparing the Call Control Platform for Outbound Calling Using Resource Groups Creating IVR Profiles and DID Groups Assigning Default Tenants and Creating Default Profiles Integrating the Reporting Server User Interface with GVP Configuring the Reporting Server Locale

Integrating Application Objects

After the Media Control Platform and Call Control Platform Application objects are created and the components are installed, they are integrated with the Resource Manager which acts as a proxy server. SIP devices and VoiceXML or CCXML applications can then make use of media-centric services through the proxy, without having to know the actual location of these resources.

This procedure is optional and required only if you want the Resource Manager to act as a proxy server for outbound requests. To integrate these Application objects with the Resource Manager, you configure the Session Initiation Protocol (SIP) settings.

This procedure describes how to integrate Application objects with the Resource Manager by configuring SIP and secure SIP options.

Procedure: Integrating Application Objects with Resource Manager

[+] Purpose

To integrate an Application object with Resource Manager by configuring the Application parameters.

[+] Prerequisites

• All of the GVP components must be installed. See [[[Procedure: Using the Deployment Wizard to Install GVP, on page 221]]].

[+] Steps

1. Log in to Genesys Administrator.
2. On the Provisioning tab, select Environment > Applications.
3. Click the Application object that you want to configure for example, the Media Control Platform or Call Control Platform Application.
   The Configuration tab appears.
4. Click the Options tab, and use the View drop-down list to select Show options in groups...
5. In the sip section, find the routeset option.
6. In the Value field, type the following:
   • sip:<IP_RM>:<SIPPort_RM>;lr to integrate the Media Control Platform with Resource Manager.
   • sip:<IP_RM>:<SIPPort_RM>:lr to integrate the Call Control Platform with Resource Manager. ...where IP_RM is the IP address of the Resource Manager, and SIPPort_RM is the SIP port of the Resource Manager typically, 5060.
     Tip

     You must include the angle brackets in the Value field in the sip.routeset and sip.securerouteset parameters.
7. In the Value field of the securerouteset option, type the following:
   • sip:<IP_RM>:<SIPSecurePort_RM>;lr to integrate the Media Control Platform with Resources Manager.
   • sip:<IP_RM>:<SIPSecurePort_RM> to integrate the Call Control Platform with Resource Manager.
     In this case, IP_RM is the IP address of the Resource Manager, and SIPSecurePort_RM is the SIP secure port of the Resource Manager typically, 5061.
     Tip

     Although the GVP components support secure SIP capabilities, the external SIP Server does not.
8. To use the Call Recording Solution through third-party recording servers: In the vrmrecorder section, configure the following options (pointing to the Resource Manager s IP address and SIP port, as shown in Steps 6 and 7):
   • sip.routeset
   • sip.securerouteset
9. Save the configuration.

• Create the connections to the Message Server. See [[[Creating a Connection to a Server.]]]

Creating a Connection to a Server

Use the procedure in this section to create connections to:

• The Message Server—Create a connection in the Media Control Platform, Call Control Platform, Resource Manager, Supplementary Services Gateway, CTI Connector, PSTN Connector, MRCP Proxy, Reporting Server and Policy Server Applications to ensure that component log information reaches the Log database and can be viewed in the Solution Control Interface (SCI).
• The Reporting Server—Create a connection in the Media Control Platform, Call Control Platform, Resource Manager, PSTN Connector, CTI Connector, Supplementary Services Gateway, and MRCP Proxy Applications to ensure that these components detect the Reporting Server to which they are sending reporting data. Genesys Administrator also requires a connection to Reporting Server to monitor GVP components.
• SIP Server—Create a connection in the Resource Manager, Supplementary Services Gateway, and PSTN Connector Applications to manage the initiation of outbound calls.
• MRCP Proxy—Create a connection in the Media Control Platform Application if you are planning to use the proxy to manage MRCPv1 RTSP traffic within the GVP deployment.
• MRCP Server—Create a connection in the MRCP Proxy Application if you are planning to use the proxy to manage MRCPv1 RTSP traffic within the GVP deployment (in the Media Control Platform Application if you are not deploying the MRCP Proxy).
• Cisco T-server—Create a connection in the UCM Connector Application to ensure the tenant DBID of the Cisco T-Server is included in Request URI in any SIP INVITE messages sent to the UCM Connector.
• The SNMP Master Agent—Create a connection in the Media Control Platform, Call Control Platform, Resource Manager, Supplementary Services Gateway, CTI Connector, PSTN Connector, MRCP Proxy, and Reporting Server Applications if you want to capture alarm and trap information.

Procedure: Creating a Connection to a Server

[+] Purpose

To create a connection in an Application object to a server or component.

• Complete the remaining post-installation activities for the Media Control Platform. See [[[Provisioning the Speech Resources.]]]

Provisioning the Speech Resources

The Media Resource Control Protocol (MRCP) speech resources are controlled by the Call Manager Application Program Interface (CMAPI), which opens and closes sessions, and provides the speech recognition and speech synthesis commands that the MRCP Server uses to carry out speech requests.

If the MRCP Proxy is deployed, the configurations in this procedure vary slightly. Therefore, the configurations are described with and without the MRCP Proxy. If you have installed the MRCP Proxy, see also Provisioning the MRCP Proxy on page 250.

Tip

The procedures in this section are required only if you are using Automatic Speech Recognition (ASR) and Text-to-Speech (TTS) speech resources, and have an MRCP Server or MRCP Proxy in your deployment.

This section contains two procedures that create the Speech Resource Applications and assign the MRCP Server or MRCP Proxy to the Media Control Platform.

Procedure: Provisioning Speech Resource Application Objects

[+] Purpose

To create the MRCP Speech Resource Applications for ASR and TTS.

[+] Summary

After a Speech Resource Application is created with the basic configuration, it must be provisioned with the IP address and port number of the MRCP Server or the MRCP Proxy (if required).

[+] Prerequisites

• The ASR and TTS servers are installed and operational.
• The MRCP Speech Resource object templates are imported. See Procedure: Importing Application Object Templates Manually, on page 313
• The MRCP Speech Resource objects are created. See Procedure: Creating Application Objects Manually, on page 318.

[+] Steps

1. Log in to Genesys Administrator.
2. On the Provisioning tab, select Environment > Applications.
3. Select the Speech Resource Application you want to configure.
   The Configuration tab appears.
4. Click the Options tab, and scroll to the provision section.
5. Enter the value for each Option as described in Table 21:

   Table 21: MRCP Application Properties Options Tab

   Option name	Option value
   For MRCPv1
   vrm.client.resource.name	Enter the identifier used to link the VoiceXML application to a common set of speech resources; for example, For ASR, enter IBM, NUANCE, or TELISMA. For TTS, enter REALSPEAK, VOCALIZER, OSR, or IBM. Notes: A common set of speech resources means that the provisioning data for each speech resource with the same name is identical. A resource with the same name but different provisioning data should not be added to the common set of resources. GVP supports dynamically removing and adding ASR/TTS servers (resources), but does not support dynamically changing a resource's provisioning data. To change a resource's provisioning data, follow these steps: 1. Remove (delete) the resource. 2. Modify the resource s provisioning data. 3. Add back (reconnect) the resource. Important: If the provisioning data of the modified resource is different from an existing common set of resources with the same name, then you must use a different name for this resource.
   vrm.client.resource.uri	The URI must contain the IP address and port number of the MRCP Server or the MRCP Proxy by using the following format: rtsp://servername:<port>/<path> For the recommended resource Universal Resource Identifier (URI), check the MRCP vendor documentation. Tip The MRCP Proxy supports MRCPv1 speech resources only.
   vrm.proxy.ping_interval	Enter a value (or retain the default) to specify the ping interval in milliseconds (used only when the MRCP Proxy is deployed). Default value: 30000
   For MRCPv2
   vrm.client.resource.name	Enter the identifier used to link the VoiceXML application to a common set of speech resources for example, For ASR, enter NUANCE. For TTS, enter REALSPEAK or VOCALIZER.
   vrm.client.resource.uri	The URI must contain the IP address and port number of the MRCP server using one of two formats: sip:mresources@<MRCP server IP>:<port>;transport=TLS sips:mresources@<MRCP server IP>:<port> (The default SIPS port number for Nuance Speech Servers is 5061.) For the recommended resource URI, check the MRCP vendor documentation.
   vrm.client.TransportProtocol	Enter one of two values: MRCPv2 without Security MRCPv2 with secure TLS

6. Save the configuration.
   Tip

   Complete Steps 7 to 10 if you are deploying MRCPv2 with Secure RTP (SRTP) only.

   Configure the Media Control Platform Application

7. Select the Media Control Platform Application that is associated with this speech resource.
   The Configuration tab appears.

   • asr.srtp.mode=offer
   • asr.srtp.sessionparams=none
   • tts.srtp.mode=offer
   • asr.srtp.sessionparams=none
10. Save the configuration.
    Configure the ASR Server
11. Configure the following options on the ASR Server:
    • If the ASR Server supports session timeout, configure 600000 (milliseconds, or 10 minutes) for the timeout value to prevent interruption of any active recognition sessions.
    • For Nuance SpeechWorks MediaServer and OpenSpeech Recognizer, configure the server.transport.sessionTimeout VXIInteger option with a value of 600000 (10 minutes).
    • For Nuance Speech Server and Nuance Recognizer, configure the server.mrcp2.sip.sessionTimeout and server.mrcp1.rtsp.sessionTimeout options with a value of 600000 (10 minutes).
      For other ASR vendors, check the vendor documentation.
12. To make the ASR service work correctly with GVP, you must edit the Nuance Recognizer file baseline.xml. and comment out the third and fourth lines in the code sample below: <param name="swirec_extra_nbest_keys">
    <value>SWI_meaning</value>
    <style="color: red;"><!--</style> <value>SWI_literal</value> <style="color: red;">--></style>
    <style="color: red;"><!--</style> <value>SWI_grammarName</value> <style="color: red;">--></style>
    </param> The characters to add to the code are marked in red.

[+] Next

• If required, complete the post-installation activities for the Supplementary Services Gateway. See Procedure: Configuring the PSTN Connector, on page 254.

Provisioning the MRCP Proxy

The MRCP Proxy is an optional component, but must be deployed if ASR and TTS usage reporting is required. You can deploy the MRCP Proxy in stand-alone or warm active standby HA mode. The procedures in this section describe the steps for each configuration.

Tip

By design, the MRCP Proxy supports only the NUANCE speech resource.

Procedure: Configuring the MRCP Proxy

[+] Purpose

To configure the MRCP Proxy to act as a proxy for all MRCPv1 traffic in the environment.

[+] Prerequisites

• The MRCP Speech Resource objects are provisioned. See Procedure: Provisioning Speech Resource Application Objects, on page 245.
• The server connections are created. See Procedure: Creating a Connection to a Server, on page 243.
• The connections to the ASR and TTS resource access points are created. See Procedure: Provisioning Speech Resource Application Objects, on page 245.

[+] Steps

1. Log in to Genesys Administrator.

5. Create a connection to the MRCP Server. See the Prerequisites section of this procedure.
6. Save the configuration.

Procedure: Configuring the MRCP Proxy for HA

[+] Summary

A configured MRCP Proxy acts as a warm standby in case of failover which means that, like a hot standby, the standby instance becomes active if the active instance fails. However, unlike a hot standby, a warm standby does not handle existing sessions. Application requests are rejected mid-stream during a failover; and applications must be designed to accommodate such a failure.

The failover sequence of events is as follows:

1. The primary MRCP Proxy terminates.
2. The LCA in the primary MRCPP machine informs SCS about this event.
3. SCS checks to see if the terminated MRCPP has a backup instance configured.
4. If there is a backup instance configured, SCS instructs through LCA in the backup computer the other MRCPP to become primary.

In a standard configuration, the MRCP Proxies are configured as backup to each other, and SCS has an HA license to perform a switch-over.

[+] Purpose

To configure the MRCP Proxy in HA mode to act as a proxy for all MRCPv1 traffic in the environment.

[+] Prerequisites

• Ensure that the latest versions of Management Framework and LCA are installed and the Solution Control Server (SCS) Application is configured to support HA licenses. See the Framework 8.1 Deployment Guide and the Framework 8.1 Management Layer Users Guide.
• See also the prerequisites in the Procedure: Configuring the MRCP Proxy, on page 250.

Tip

The prerequisites for the MRCP Proxy backup server are the same as for the primary in HA mode, and the connections must be the same on both MRCP Proxy Applications in the HA pair.

[+] Steps

1. Complete Steps 1 to 5 in the [[[Procedure: Configuring the MRCP Proxy, on page 250]]] for both MRCP Proxy Applications in the HA pair.
2. In the primary MRCP Proxy Application, click the Configurations tab.
3. In the Server Info section, in the Backup Server field, browse to the backup MRCP Proxy Application and click to select it.
4. In the Redundancy field, select warm-standby.
5. Save the configuration.
   Connect to the MCP
6. In the Media Control Platform Application, create a connection to the primary MRCP Proxy.
7. Save the configuration.

Provisioning the PSTN Connector

The procedures in this section describe how to configure the mandatory parameters for the Public Switched Telephone Network (PSTN) Connector Application object and the how to integrate the PSTN Connector with SIP Server. There are many more configurable parameters for the PSTN Connector, all of which are optional. For a complete list and description of configuration options, see the Genesys Voice Platform 8.5 User's Guide.

The PSTN Connector component is required if you are planning to migrate from GVP 7.x Voice Communication Server (VCS), or a VoiceGenie (VG) TDM interface to GVP 8.1.2 or later.

This section contains procedures for Configuring the PSTN Connector and Configuring a Trunk DN for the PSTN Connector.

Procedure: Configuring the PSTN Connector

Purpose
To prepare the PSTN Connector to manage inbound and outbound calls for GVP.

Prerequisites

• All of the GVP components are installed. See Procedure: Using the Deployment Wizard to Install GVP, on page 221.
• The connections to Message Server, SIP Server, and the SNMP Master Agent are configured in the PSTN Connector Application object. See Procedure: Creating a Connection to a Server, on page 243.
• SIP Server is installed. See the Voice Platform Solution 8.1 Integration Guide.

Steps

1. Log in to Genesys Administrator.
2. On the Provisioning tab, select Environment > Applications.
3. Select the PSTN Connector Application object that you want to configure.
   The Configuration tab appears.
4. Click the Options tab, and from the View drop-down list, select the Mandatory Options view.
5. In the DialogicManager_Route1 and GatewayManager sections, enter the values for the mandatory options as shown in Table 23.

   Table 23: PSTN Connector Mandatory Parameters

   Section	Option	Value
   DialogicManager_Route1	RouteType	Specify one of three route types or call directions for this route, enter: 0 for Inbound 1 for outbound 2 for In/Out (See Note below, in this table.)
   	Signaling Type	Specify one of five signaling types, enter: 0 for T1-ISDN (PRI) 1 for Analog 2 for E1-ISDN (PRI) 3 for T1-RobbedBit 4 for E1-CAS
   	Channels	Specify the ports for this route by using the format, [<Card>:<PortRange>,<Card>:<PortRange>]. You can provision more than one board in a route and a partial range of ports in a board for example: 1:1-23 1:1-23,2:1-23 1:1-30,2:1-30 1:1-12,2:1-15
   GatewayManager	SIP Destination IP Address	Enter the SIP endpoint IP address that will receive SIP calls from the PSTN Connector. (This is the IP address for SIP Server or the Resource Manager, depending on your configuration.)
   	SIP Destination Port Number	Enter the SIP endpoint port number of the server that is configured in SIP Destination IP Address.
   MediaManager	Supported Local Codec Type	Enter the audio format that is in use on the TDM trunk: 0 - Mulaw 8 - ALaw
   Notes The Inbound & Outbound route type is supported only on ISDN (PRI) lines. If you select one of these route types, ensure that you use a compatible signaling type. If you are using a T1-Robbed Bit or E1-CAS interface, options in the T1rb options group must be configured, specifically the T1rbProtocolFile option, see the component metadata. For JCT boards only, a separate span is required to support ASR or recorded VoiceXML applications in T1-ISDN, E1-ISDN, or E1-CAS environments. The MediaVoxResourceBoard option must be configured with route number that is used for CSP. When JCT boards are used with the PSTN Connector, and the VoiceXML application uses ASR or recording media, not all the spans can be used for call handling. For each span that is configured to take calls, there must be another dedicated span for streaming echo cancelled audio to the Media Control Platform. Therefore, if Route1 is configured to handle calls on span1 (for example, ports=1:1-23), the MediaVoxResourceBoard option under the DialogicManagerRoute1 section should be set to 2. Repeat the same steps if you have configured a DialogicManager_Route2 section. This restriction does not apply in the following scenarios: The VoiceXML application is a pure DTMF application (does not use ASR or recording media). The VoiceXML application uses ASR but the JCT board is configured with the T1-Robbed Bit protocol.

6. Create additional DialogicManager_Route<N> sections as required (for example, you may want to create a section for inbound ports and one for outbound ports):
   1. From the View drop-down list, select either Advanced View (Options) or Advanced View (Annex).
   2. Right-click on the Section column heading and select New.
   3. Enter DialogicManager_Route2 for the Section name, Description for the Option name, and Route2 Information for the Value.
   4. Click OK.
   5. Copy and paste all of the options from the DialogicManager_Route1 and DialogicManager_Route2 sections, modifying the mandatory values as required.
   6. Repeat these steps as required.
   Tip

   Dialogic Circular Buffer Size
   When you configure the PSTN Connector application, set the value for [DialogicManager] DialogicTransferBufferSize to 2048. This specifies the size of the Dialogic Circular buffer which is used for transferring data to the Dialogic firmware. The default value of this parameter on Windows is different, but must be set to 2048 for Linux. If not, the Dialogic may return LOW_WATER_MARK warnings during initial play of the media, which interferes with normal audio play and may result in the prompt being cut off.

   Save the configuration.

End Next

• Configure the Trunk and Trunk Group DNs for the PSTN Connector. See Procedure: Configuring a Trunk DN for the PSTN Connector.

Procedure: Configuring a Trunk DN for the PSTN Connector

Purpose
To configure SIP Server with a Trunk DN, which points to the PSTN Connector Application object to ensure outbound calls can be routed to a specific PSTN Connector instance.

Summary
You can deploy multiple PSTN Connectors, however, you must ensure that SIP Server routes the outbound call to the same PSTN Connector instance as the inbound call. This procedure includes configuration options to enable this functionality.
