Network Management Console settings for Android

ZelloWork networks are highly customizable, allowing Admins to adjust user and device settings remotely from the Management Console. To go to your Management Console, type in your network's URL: networkname.zellowork.com. For example, if your network is named "mycompany59", the URL would be "mycompany59.zellowork.com". Sign-in with the username of admin and your password.

Accessing console settings 

  1. From the Management Console, select Settings from the taskbar.consolesettings.png
  2. From the right side-bar, select Android.

NOTE: Settings noted with an asterisk * below can be set as the default using the Management Console. Users can change the default setting on their device and it will stay in effect until the user logs off. Once the user logs back in, the setting reverts back to the default on the Management Console.

Please note that for other settings present in both the Management Console and the Zello app, configuring the setting in the Management Console will prevent users from changing the setting on their device.

General settings

Bring to the foreground when receiving: A user may switch to other apps when not using Zello. When someone contacts the user, this option brings the Zello app to the foreground.

Turn display on when receiving: In order for this setting to work, Bring to the foreground when receiving must be on. This will turn the screen on when a message is received.

Automatically activate a contact: Automatically brings the user to the talk screen for a given contact when a message from them comes in.

Bring to the foreground when push-to-talk button is pressed: Toggle on or off. When you are using a hardware device with an external PTT button, toggling this setting “on” will automatically bring Zello to the foreground when the external PTT button is pressed. 

Hardware knob mode: Only applicable to network radios or other devices with external knobs that are used for channel selection. This setting gives you a dropdown list of options that the knob will show you: 

Remove user account info from device on exit: When this setting is toggled on, the android devices in your network will not store user login information when the user exits the Zello app. This prevents sign-in credentials from being stored on a shared device after the user exits Zello. Learn more. Note that this is different from Shared Device functionality, which allows multiple shift workers to utilize the same Zello Work user. 

Notify about all unanswered calls: Toggle on to show a missed message badge for all incoming messages which have not been answered.

Automatically connect channels: Toggle on to connect the user to all channels as soon as they sign in. Only applicable to channels from which the user can disconnect. Learn more

Sort channels by status: Toggle on to place connected channels at the top of the Channels list, and disconnected channels at the bottom. When toggled off, channels are sorted alphabetically.

Font Size Boost: Allows you to increase the size of font in the Zello app for all Android users. Note that selecting an option for this from the console will prevent users from customizing it on their own devices. 

Recording amplifier (dB)*: Move the slider to the left to make outgoing audio softer or to the right to make outgoing audio louder.

Recording automatic gain control (beta): When toggled on, this overrides the Recording amplifier setting.

Increase volume on incoming message after inactivity (beta): Automatically increases the volume of an incoming message after 10 minutes of inactivity. Helps your users avoid missing messages

Playback amplifier (dB)*: Move the slider to the left to make incoming audio softer or to the right to make incoming audio louder.

Playback automatic gain control (beta): When active, this overrides Playback amplifier setting.

Noise suppression: Reduce background noise when recording.

PTT key code override:

Headset sequence mode:

Use Bluetooth Classic (SPP) for the AINA Voice Responder button:

Wake the device to keep Zello connected: Prevents Zello from shutting off when in the background. Toggling off this setting will disable the keep-alive interval. 

Keep-alive interval (mobile)*: This is the polling time between the app and the service. A longer time polling time uses less bandwidth and improves battery life for those using the Android device. A shorter polling time keeps the user status display current and may improve connectivity. For most users, the default value should work fine. Options are s for seconds and m for minutes.

Use TCP only (mobile)*: Speeds sign in and improves cellular connection reliability. However, it may delay receiving messages in real-time. The alternative is TCP and UDP connectivity. Learn more here. 

Keep-alive interval (WiFi)*: This is the polling time between the app and Wi-Fi. A longer time polling time uses less bandwidth and improves battery life for those using the Android. A shorter polling time keeps the user status display current and may improve connectivity. For most users, the default value should work fine. Options are s for seconds and m for minutes.

Use TCP only (WiFi)*: Speeds sign-in and improves Wi-Fi connection reliability. However, it may delay receiving messages in real-time. The alternative is TCP and UDP connectivity. Learn more here. 

Status lockdown: Prevents users from turning off "Available" status. Learn more about Zello status here. 

Remove the Exit option from app menu: Prevents users from exiting the app and going into standby status. Use this in addition to Status lockdown to keep users in Available status.

Hide on inactivity: Minimizes the Zello app if it has been inactive for the selected length of time. Choose a length of time between six and sixty seconds, or Never to disable the feature. This does not log the user off, but the app will simply disappear from the foreground. 

Location sharing: Allows users to send their current location to another contact. The user’s location can still be seen in the management console if this is toggled off. 

Auto-run on startup: The Zello app starts automatically when the device is turned on. 

Set Zello status to Busy when phone is in silent mode: Automatically changes status to Busy when the user puts the phone in silent mode. This will prevent new messages from playing aloud. 

Allow messages playback during phone call: When toggled on, messages will play aloud while the user is in phone calls. 

Disable per user volume adjustment: When toggled on, prevents users from adjusting message volume for individual contacts. Learn more.

Disable option to mute selected users and channels: When toggled on, prevents users from muting other users and channels.

Playback buffer:

Allow overlay buttons: When toggled on, Android users can generate a talk button that allows them to send audio messages to a specific channel or contact while Zello is in the background. Learn more.

Allow extended notification in the Android system tray: When turned on, the Zello notification bar will show the last contact and allow the user to send a message directly from the pull-down notifications menu: 

Call pre-setup: Allows faster call setup for repeated calls to the same contact. Uses more data.

Asynchronous message delivery: Queues missed messages while in 'Standby' status and autoplays once the Internet connection is back and status is 'Available'.

Debug log size: Adjusts the amount of memory reserved for the application's debug log. Set to Large to store 10 times as many log messages. Note that you will not need to change this setting unless requested by the Zello team during troubleshooting.

Voice quality

Samples per second: It’s best to leave it as-is unless you’re familiar with this. This setting provides a dropdown menu that allows you to choose 8kHz, 16 kHz, 24kHz. This refers to the number of “samples” recorded every second - if you’re not familiar with this term, here is a straightforward explanation. A higher Sampling rate will produce higher quality transmission audio.  Refer to the Speex Codec manual for more information.                                                                 

Bitrate: It’s best to leave it as-is unless you’re familiar with this. A drop-down menu that allows you to choose Auto or 6,8,16,32,64,128 kbps. This refers to the amount of data used per second in sending an audio transmission. A lower bitrate will save data, but will produce lower-quality audio. Here is a more in-depth explanation. Refer to the Speex Codec manual for more information.                                  Frames per packet: The number of frames, or audio samples, per packet. [Frames per packet]*[Frame size] must be <= 120.

Frame size: The length of a sample in milliseconds. [Frames per packet]*[Frame size] must be <= 120.                                           

Jitter adjustment threshold (%): Jitter is audio packets getting lost or delayed during transmission. Jitter adjustment actively corrects for the effects of jitter to maintain audio quality. This setting controls the algorithm that adjusts jitter on Android devices in your network. Higher values reduce the chances of breaks in communication. Lower values reduce latency at the expense of increased probability of breaks in incoming messages.
