BOGEN NQ-GA10P Nyquist VoIP Intercom Module

Configuring the Nyquist VoIP Intercom Module

Bogen’s plenum-rated Nyquist Voice over Internet Protocol (VoIP) intercom modules transform any low-impedance analog speaker into a full-featured Power- over-Ethernet (PoE) IP speaker. The modules use the latest technology to deliver superior audio quality, making them perfect for IP paging and audio distribution. The built-in talkback capability allows these modules to be used in VoIP intercom applications. These 10W single-channel intercom modules are available with (NQ-GA10PV) or without (NQ-GA10P) an HDMI video output, depending upon the application needs. They also offer a CAN bus interface to work with the NQ-E7020 Digital Call Switch and a Form-C relay for controlling third-party devices (e.g., A/V override). When paired with Bogen’s ANS500M microphone module (optional), these intercom modules can be turned into an ambient noise sensor to help maintain paging and back-ground music intelligibility in high-noise environments. Alternatively, it can be paired with the Bogen DDU250 Dynamic Desktop Microphone and configured as a push-to- talk microphone station, allowing it to perform a preconfigured zone page or All-Call page (including Emergency and Multi-Site). If an HDMI video device is attached, this device can display messages and images sent by a Nyquist server, as well as a digital or analog clock. These messages can be used for scheduled announcements, emergency instructions, automatically triggered messages, simple ad-hoc messages, or many other purposes. If a Nyquist server is not present, the device will display an analog clock. For further information on displaying and scheduling messages, see the “Managing GA10PV Display Messages” section of the Nyquist System Administrator Guide. The Nyquist server or System Controller can automatically discover and configure the VoIP intercom module, but you can also manage the device, and manually configure some settings, through the VoIP Intercom Module’s web-based user interface (web UI). A two-second press of the appliance’s Reset button reboots the device. If you press the Reset button for 10 seconds, the appliance returns to the factory default configuration settings. Returning to the default configuration settings does not change the appliance’s firmware. The following sections describe the process for manual configuration. For information about using Nyquist’s automatic configuration process, refer to the appropriate Nyquist System Administrator Guide.

Note: Do not use third-party Chrome browser extensions with the Nyquist user interface.

To access the appliance’s Web-based user interface (UI):

1. Before accessing the web UI for the first time, the Bogen Certification Authority (CA) digital certificate must be installed on the client. This certificate can be downloaded from any Nyquist appliance and enables your browser to recognize the Nyquist web application as a trusted site. For details on how to download and install the certificate to your client computers, see “Installing the Bogen Digital Certification Authority” on page 19.
2. Access the appliance’s web UI by doing one of the following:
   • On your web browser, enter the IP address for the appliance as the URL.
   • From the Nyquist server’s web UI navigation bar, select Stations, select Stations Status or Appliance Status, navigate to the device that you want to configure, and then select the Link icon.
3. At the Nyquist appliance’s Login page, enter username and password, then press enter or click on the Login button.

The default username is admin; the default password is bogen.

Note: After a successful login, a warning will be displayed if the default password is still in use. We strongly encourage changing the default password as soon as possible. When you have logged in successfully, you will be presented with the dashboard for the appliance.

Using the Dashboard

The dashboard displays the following fields:

Table 1. Appliance Dashboard Fields

• Device Type Identifies the model of this device.

Standalone Operation

This device can also run in Standalone Operation mode, where it will not interact with a Nyquist server (e.g., E7000 or C4000). This means the device will not:

• Fetch device configuration from Nyquist server
• Register with Nyquist server (via SIP)
• Store backup information to Nyquist server
• Allow access to Nyquist server-based NTP
• Display messages or images from the Nyquist server

Standalone Operation allows this device it to be used without a Nyquist server as a generic SIP endpoint when integrated with a 3rd-party VoIP telephone system or other SIP server-based solutions, such as a unified communications (UC) platform. In a non-SIP environment, these devices are capable of receiving audio through one or more prioritized multicast channels.

Updating Firmware

When you select Firmware Update from the appliance’s web UI, the Firmware Update page appears. From this page you can determine which Nyquist firmware version the appliance is using and if an update is available. You can also load a firmware release, install the loaded firmware, restore the configuration to factory defaults, and reboot the appliance.

Note: A Nyquist appliance connected to the Nyquist network receives a configuration file from the Nyquist server that includes the latest firmware available from the server. If the firmware is different from the one installed on the appliance, an automatic firmware update occurs unless the Firmware parameter for the station is left blank. Refer to the Nyquist System Administrator Guide for more information.

To use the Firmware Update page:

1. On the appliance web UI’s main page, select Firmware Update to view or update the firmware version.

   • If the device is in Standalone mode, the Check for Updates button will be shown. Selecting it checks the Bogen website for the latest firmware version available. If a version newer than the one currently installed is found, it is downloaded to the appliance and the Update Firmware button will be shown.

   • If you already have a firmware file you would like to install to the appliance, select Upload Firmware to upload the firmware file from your computer to the appli-ance. A popup screen appears that allows you to select the file that you want to upload. You can navigate to the file’s location. After you select the file, select Upload.
     The page displays the uploaded firmware version (“New Nyquist Version”) and an Update Firmware button appears. Select this button if you want to update the appliance’s firmware to the uploaded version.

   • If you want to return your appliance to its original factory configuration, select Restore Factory Settings.

   • Select Reboot Appliance to restart your appliance.

Viewing the Certificate

The following steps outline how to view and verify the TLS/SSL certificate that was provided by the Nyquist device.

Important: The user interfaces for browsers change not infrequently, so the exact details may vary from what is described in the following instructions. Some security packages can also affect the information available, such as antivirus software that injects its own CA certif-icate in lieu of the website’s actual certificate, which has the effect of hiding the actual certificate from the user.

1. Browse to the Bogen device’s web application in your browser (using Safari on iOS, Chrome or Edge on all other platforms).
2. Select the lock icon on the address bar of the browser (to the left of the URL).
3. Display the CA certificate by following one of the following steps:
   • On the Chrome or Edge browser, select Connection is secure, then select either Certificate is valid, the certificate icon, or Certificate information to display the Certificate Viewer dialog. Select the Details tab, then Bogen CA in the Certificate Hierarchy section.
   • On the Safari browser [MacOS or iOS only], select Show Certificate in the window that appears.
   • As an alternative on Android devices, select the Android system’s Settings > Biometrics and security > Other security settings >View security certificates, select the USER tab, and select the Bogen certificate.
4. Verify that the Bogen CA certificate is selected and not the server certificate (the server certificate’s name will be an IP address). To verify that the certificate is valid, verify that the displayed fingerprint values match the following:
   • SHA-1: 0A 82 48 F6 9D 97 0F 8D D8 55 D0 E0 59 29 72 DA 64 B1 A8 45
   • SHA-256: 6B D0 D5 8D C8 F7 E8 03 9E A3 F1 52 32 1D 9C 5C 58 8B 4E FA DF 03 43 64 34 C2 6C 63 C5 4A AC 46
