Access to people in your TASSTA network

In the TASSTA network, subscribers have associated user accounts, which are managed by TASSTA administrators. Interaction among users takes place individually or in channels, which are also managed by administrators. The terms channel and group are used interchangeably in the TASSTA framework most of the time.

In addition to the groups predefined by administrators, T.Rodon lets the operator create dynamic groups and dynamic calls if necessary; both of these modes of communication are essentially temporary channels.

A TASSTA user cannot go without a group by design, because a user must be reachable by group talk through PTT whenever possible. A user, including an operator, is always attached to exactly one group at a time, although they can listen to multiple groups at once if this is allowed by the administrator. Each user has a default group, meaning a group that the user is in if they have not joined any channels or have left non-default channels.

From an operator's standpoint, groups are organized into a tree. The root group in this tree is usually called "Main". It is normally set as the default group for users. The root group is also the catch-all group for users with a non-root default group. If that default group is deleted or becomes inaccessible due to permission changes, the user ends up in the root group.

Your primary tools for access to the users and groups in the TASSTA network are the group tree and the user list, which are located in the left pane of the T.Rodon main window. For convenience, sorting and filtering controls are provided. They are shared by the user list and group tree and can help you quickly locate the users and groups you need, especially in large networks.

Notes:

You can only see the groups that your user account is allowed to enter, as determined by rules on the server. Therefore, the group tree representations for the same TASSTA network may vary from operator to operator.
If a group changes its background color to yellow in the group tree, that means too many users have joined it, exceeding the maximum recommended number set by the administrator in T.Commander. Consider asking the members of that group to change groups, unless they urgently need that group.
Depending on how the administrator has configured the server properties, users may disappear from the user list when they go offline or switch to channels that you cannot view.

Your left pane may contain a drop-down menu for selecting a zone. A zone is an administrator-defined collection of channels. The zone selector appears only if at least one zone is configured on the server. When you select a zone, only the channels included in that zone become visible. To view all available channels without filtering by zone, select the No zone selected option in the drop-down menu.

Note:

Despite the name similarity, these zones are not associated with geo-zones from the Map Tools plugin in any way.

Allowlisting users and groups

To limit your scope to a particular collection of users and groups, create a contact book, which acts as an allowlist. Channels that are not in the contact book will be hidden from group tree. Users will be visible in the user list as long as they are directly in the contact book or in any of the allowlisted channels.

To configure this, go to the Contact book page in the settings.

Actions on users

Right-clicking a user in the user list gives you a shortcut menu with actions that you can perform on the user. What items are available in the menu depends on the state of the network and multiple sources of configuration. The following operations can be done:

What you can do	Shortcut menu items	Details
Make a one-to-one call (or leave a message if offline)	Call Call (direct) Video call Push-to-Video	For more information, see One-to-one voice communication.
Get device information	Info	You can remotely view the following information about the device of any connected user: Battery power level Whether the device is charging GSM/LTE signal level Type of connection to the Internet GPS sensor status Bluetooth status
Remotely capture audio, pictures or video from the user's device	Listen ambience Take picture (front camera) Take picture (back camera) Remote video (back camera) Remote video (back camera)	For more information, see Remote media capture.
Start text chat with the user	Message	For more information, see Messaging.
Mute and unmute a user	Mute	Muting a user is local to your computer only.
Find out where the user was last seen	Last known location	You are taken to the map view, and the user's last known location is marked in it.
Configure additional messaging destinations for the user	MCGW channels configuration	Messages can be forwarded as SMS or email. For more information, see Messaging.
Exchange keys with the user for end-to-end encryption	Share key	For more information, see End-to-end encryption for voice and messages.

Actions on groups

Right-clicking a group in the group tree gives you a shortcut menu with actions that you can perform on the group. What items are available in the menu depends on the state of the network and multiple sources of configuration. The following operations can be done:

What you can do	Shortcut menu items	Details
Select the group as the PTT destination	Select	It is the same as simply clicking the group.
Select which groups you want to listen to simultaneously	Listen	For more information about multilistening, see Voice communication.
Mute and unmute a group	Mute	Muting a group is local to your computer only.
Configure additional messaging destinations for the group	MCGW channels configuration	Messages can be forwarded as SMS or email. For more information, see MCGW.
Remove a dynamic group	Release	You cannot remove administrator-defined groups using T.Rodon.
