Last Updated : Jun 05, 2026 |

Use these pages to add a new Media Processing Platform (MPP) to the Experience Portal system.

Add MPP Server page (page 1 of 2)

Field

Description

Zone

The name of the zone where the MPP server is configured. Select the name of the zone from the drop-down box.

Note:

The Zone drop-down box appears only if you have created zones on your Experience Portal system. If you do not create any new zones, you do not see the drop-down box.

Name

The unique identifier for the MPP server on the Experience Portal system.

This name is used only in the EPM web interface and cannot be changed after you save the new MPP.

Host Address

The network address, or location, of the computer on which the MPP server resides. The EPM uses this address to communicate with the MPP server.

This address can be a fully qualified domain name or an IP address, but the address must be unique on this Experience Portal system and the machine must already have the MPP software installed on it.

You cannot use any of the following hostnames: 127.0.0.1, localhost, or localhost.local.domain.

Continue

Submits the name and host address to Experience Portal for verification.

Experience Portal verifies the host address by attempting to download the Secure Sockets Layer (SSL) certificate from the designated MPP. If the SSL certificate fails to download, Experience Portal prompts you to correct the Host Address field entry and try again.

When the SSL certificate downloads successfully, Experience Portal displays the second Add MPP Server page.

Add MPP Server page (page 2 of 2)

This page contains the:

General section

Field

Description

Name

The name you entered on the first Add MPP page.

Note:

This field cannot be changed.

Host Address

The network address, or location, of the computer on which the MPP server resides. The EPM uses this address to communicate with the MPP server.

This address can be a fully qualified domain name or an IP address, but the address must be unique on this Experience Portal system and the machine must already have the MPP software installed on it.

You cannot use any of the following hostnames: 127.0.0.1, localhost, or localhost.local.domain.

Important:

If you entered an incorrect host address on the first Add MPP page, Experience Portal displays an error message in red next to this field. You must correct this error before you can save the new MPP.

Network Address (VoIP)

The IP address the telephony servers must use to communicate with the MPP.

Network Address (MRCP)

The IP address the speech proxy servers must use to communicate with the MPP when processing ASR and TTS requests.

Tip:

This address is usually the same as the host IP address.

Network Address (AppSvr)

The IP address the application servers must use to communicate with the MPP.

Tip:

This address is usually the same as the host IP address.

Maximum Simultaneous Calls

The maximum number of calls that this MPP can handle at any one time. It is equivalent to the maximum number of ports that Experience Portal will allocate to this MPP.

Enter an integer in this field.

Note:

For assistance in sizing your MPP server capacity and setting the correct value for the Maximum Simultaneous Calls parameter for each MPP server, contact your Avaya Services representative or Avaya Business Partner. For more information, see Avaya Experience Portal Overview and Specification on http://support.avaya.com.

Restart Automatically

The options are:

  • Yes: If the MPP stops unexpectedly, Experience Portal brings it back online automatically.

  • No: If the MPP stops, it must be manually restarted.

Note:

This option also affects an MPP that has received an explicit Reboot or Halt command. For details about issuing a Halt command and changing the operational state of one or more MPPs, see Administering Avaya Experience Portal on http://support.avaya.com.

Listed Directory Number (LDN)

This field is only shown when you are logged into the EPM using the Avaya Services init account created when the Avaya Service accounts were configured.

If you are logged into the EPM using the init account, enter the LDN number for this server as it appears in the Avaya Services database. If an LDN number is not specified for this server, Experience Portal uses the default value (000)000-0000.

MPP Certificate section

Field

Description

Certificate display box

The SSL certificate issued by the MPP. The displayed certificate must exactly match the certificate that was established when the MPP was first installed.

Trust new certificate

If this MPP has just been installed or upgraded, this check box is displayed in this section. If you see this check box, make sure the certificate is valid and then select the check box.

You cannot save the MPP until the certificate is accepted.

Categories and Trace Levels section

Performance tracing is a valuable troubleshooting tool, but it can adversely impact Experience Portal system performance if you set all categories to Finest on a busy production system. If you need to troubleshoot a particular area, you must set specific categories to Fine and examine the resulting output to see if you can locate the issue. If not, set the level to Finer and repeat the process. If you still need more data, then set the level to Finest and keep a close watch on system resource usage.

Note:

If these fields are not displayed, click the group heading to expand the group.
