Using LumenVox with Avaya Voice Portal

The LumenVox speech recognition software is compatible with the Avaya Voice Portal platform (for other platforms, including Voice Portal, see Working with Platforms). This is done via the MRCPv1 connection, so before you begin you will need to have the following installed:

• A working Avaya VP platform (we have tested with VP 4.0; the Speech Engine may work with other versions but at this time we cannot say for sure). You must have already enabled speech recognition on this system — you may refer to our more complete Avaya VP/LumenVox Application Notes for more information on this.
• The LumenVox MRCPv1 Server (see our installation instructions)
• The LumenVox Speech Engine and License Server. These may run on the same machine as the MRCPv1 Server or different machines. (See our installation and licensing instructions for Windows or Linux.)

To configure Avaya, you will use the Web-based administration tools and choose the Speech Servers option under the System Configuration section:

1. Select the ASR tab and click the Add button to add a new ASR server.
2. You can leave most of the settings at their default, but the Engine Type should be set to IBM WVS.
3. Set the Network Address to the IP address of the LumenVox MRCPv1 Server.
4. Ensure that the RTSP URL is the IP address of the server with /media/recognizer on the end of it. So if your MRCPv1 Server were on a machine with the IP address of 10.0.0.1, you RTSP URL would be 10.0.0.1/media/recognizer

Once you have configured your Avaya VP machine to point to the MRCPv1 Server, you will need to make two changes to the LumenVox MRCP configuration file:

1. The mrcp_server_ip must be set to the actual IP address, not the loopback. You cannot use 127.0.0.1 for this and must put in the actual IP address of the machine hosting the MRCPv1 Server.
2. The resource_string must be set to media/recognizer and not left at the default recognizer.
3. Optional: if your Speech Engine is running on a different server from the MRCPv1 Server, you must change sre_ip to the IP address of that machine.
