For example, if the number of alarms to aggregate is set to 10, the time interval is set to 60 seconds and then after 60 seconds there are only 5 alarms raised according to the forwarding rule, then 5 alarms are forwarded. 4.5 Internal Mail Server AudioCodes has an internal mail server that is used for Alarm forwarding. This option is configured in the Alarm Forwarding Destination rule. This feature has been enhanced through the customization of the IP address and name for this server that is displayed to the mail recipient (instead of displaying the actual host name and IP address). Release Notes 20 Document #: LTRT-90548

Release Notes 4. New Features in Version 7.6 4.6 Colored Indications for Form Entity Fields When updating form entities, for example, adding a device, fields and tabs with missing or incomplete information are outlined in red and fields that are currently being edited are highlighted in yellow.

In addition, when entity is selected, the Network Summary pane is updated with the device or link details. This feature is designed to make searching for devices and sites in large deployments easier. If you drag a node to change its location, the Save button is displayed and highlighted. In the screen below, the nodes answering the search results are highlighted and when you hover over one of these nodes, the sub-nodes answering the criteria are also highlighted. If you are searching for a specific device, then once retrieved, only this device is displayed. You can easily return to the Center Map view by clearing the search field. Release Notes 22 Document #: LTRT-90548

Release Notes 4. New Features in Version 7.6 An identical set of actions that are currently supported in the Devices screen such as Reset Redundant, Lock/Unlock and Switchover are now supported in the Fixed and Floating License Pool screens.

Mutual HTTPS Authentication can now be configured for endpoint connections using the new option IPP HTTPS Authentication Mode (Security > Apache Security Settings > IPP HTTPS Authentication Mode). Trusted Root CA certificates can be added as a stand-alone action using the EMS Server Manager option Trust Store Configuration (Security > Apache Security Settings > Trust Store Configuration). This option is implemented for supporting mutual authentication between the endpoints and OVOC (see above). A new option for changing the Application Logging Level for FAEs has been implemented (Diagnostics > Logger Levels). Version 7.6 25 One Voice Operations Center

One Voice Operations Center 4.11 IP Phone Manager 4.11.1 Provisioning of Non-Skype for Business Phones Non-Skype for Business users can now be associated with devices upon user login to the phone and therefore only users need to be imported to the IP Phone Manager in the pre-staging deployment stage. Until now for non-skype for Business devices, both users and devices needed to be imported to the IP Phone Manager and this association was only supported with MAC address mapping. Now, you can associate a Non- Skype for Business user to a device with user and password authentication as was previously supported only for Skype for Business phones. 4.11.2 Session Timeout The IP Phone Manager Session timeout now inherits the configured OVOC operator Session Leasing Period parameter value. 4.11.3 Update Firmware with Delay The Devices Status page includes an option to update firmware for a batch of devices with the option to configure a delay timeout between batch runs. This feature was previously supported for actions in the Manage Multiple Devices screen. Release Notes 26 Document #: LTRT-90548

Release Notes 5. Known Limitations and Workarounds 4.11.4 Support for the Polycom VVX Phone This release adds support for the Polycom VVX Phone. 4.11.5 Allow Only Devices into OVOC that were added by the Administrator This feature ensures that only devices defined by administrators in imported prestaging files are authorized to connect to OVOC. This prevents unauthorized devices establishing connection with OVOC upon initial connection to the network. 5 Known Limitations and Workarounds The table below lists the Known Limitations and Workarounds in this release. Known Limitations and Workarounds Issue High Availability on OVOC Bare Metal platform Problem/Limitation High Availability is not supported for OVOC servers on Bare Metal platform. Comments and Workaround High Availability- AudioCodes devices When there is active call traffic on AudioCodes HA devices during HA switchover, the OVOC QoE application does not recognize this traffic and therefore does not display and calculate the QoE data for this traffic. Applicable for all AudioCodes HA devices. This will be fixed in a future release. External Server Authentication External Server Authentication is not supported for TACACS. - Multi-tenancy is not supported for RADIUS and LDAP Active Directory users. The option Use LDAP Credentials for Device Page Opening is not supported for operators when the LDAP Level parameter is set to Admin (1) The option Use RADIUS Credentials for Device Page Opening is not supported for operators when the RADIUS User Level parameter is set to Administrator (100) - This will be fixed in a future release. Version 7.6 27 One Voice Operations Center

One Voice Operations Center Issue Problem/Limitation Comments and Workaround Certificates Activate MIB browser & Putty. Network & server Hardware/Software configuration monitoring If you have installed SSL certificates for Microsoft Active Directory, MS-SQL Server or for LDAP User authentication and you then run the Server Certificates Update procedure in the EMS Server Manager, these Microsoft certificates are overwritten. If you are configuring the connection to the MS-SQL server with SSL using a certificate file, and then one of the following occurs: Reload of a different certificate file for this SQL server. Adding of an additional SQL server with a different certificate file. The connection between OVOC and the MS SQL server may fail. MIB browser and Putty cannot be activated from the OVOC Web. (EMS > Help > server conf frame). Before running the Server Certificates Update procedure, ensure that you have backed up the Microsoft Certificates to an external location. After running the Server Certificates Update procedure, reload the Microsoft Certificates in the OVOC Web. After reloading the new certificate file, restart the OVOC server using the EMS Server Manager. This issue will be fixed in a future release. These applications can be activated as Stand-alone applications. This will be fixed in a future release. Private Labeling This version does not support private labeling. - Automatic Updating of Device s SNMP Credentials. Performance Monitoring When SNMPv2 or SNMPv3 settings are changed for the tenant, site or devices, the devices SNMP configuration is not automatically updated (only the OVOC database is updated). Performance Monitoring is not supported in this release. Directly update the devices SNMP settings. This will be fixed in a future release. This will be supported in a future release. Device Performance Monitoring Thresholds Setting can be performed via device local management (using SNMP or an ini file). Release Notes 28 Document #: LTRT-90548
