New PTT Group management in web admin

The GroupTalk PTT service has been updated with new “PTT Group management” settings in the web admin. This allows an organisation to centrally manage which PTT Groups a user shall automatically join when going on-line in the GroupTalk app on Android or iOS.

Settings for “Select PTT Group”

  • Manually (as is today): the user will manually select which PTT group to join when a user goes on-line.
  • Automatically: the user will automatically join the specified PTT group when the user goes on-line, but can afterwards manually select to join another PTT group.
  • Always: the user will automatically be forced to join the specified PTT group and can never leave it, when the user goes on-line.
  • Never: the user does not have access to the PTT Group.

Settings for “Scan Groups”
In GroupTalk a user can “scan” zero, one or many PTT Groups in addition to being in a primary PTT Group. The same settings are available for Scan Group as for Select Group; Manually, Automatically, Always and Never.

Listen Only
PTT Groups can be set to Listen Only, creating “Announcement Groups” that allow large number of users (currently up to five thousand users in a group) to listen into a group and restricting it so only one or a few users are authorised to speak into the group.

Downtown Guards with markupIllustrates the new PTT Group settings that are available in the web admin by clicking on “User categories” and “PTT Groups in this category”

In the above example the User Category “Downtown Guards” has been configured so that the following will happen when a user in that User Category goes on-line in the GroupTalk app.
  • The user will “Automatically” join the “Downtown” PTT Group.
  • The user will “Always” scan the “Announcements PTT Group, which means that the user can not stop scanning the Group.
  • Listen Only is selected for “Announcements” which means that the user can only listen to what is being said and is not authorised to speak into that PTT Group.
  • The user can “Never” listen or speak into the “Team Leaders” PTT Group.
  • The user can “Manually” join the “West District” Group if desired, but will not join the Group when the user goes on-line.


GroupTalk for Android 3.2.19

Main features of this update:
Listen in using VoIP when panic alarm is activated
When a user activates a panic alarm on a device running GroupTalk, the device can place a phone call (GSM/PSTN) to an emergency central in order to remotely monitor / listen in on what is happening around the device that activated the alarm.

In this product update, Listen in using VoIP (Voice over IP) is available as an option. Actually this is a much better solution than using GSM, since with VoIP the service can verify that the voice channel has been established. The voice can also be received in the GroupTalk PC Dispatch making it much easier for the operator to know which voice stream that belongs to which panic alarm being received.

In the near future it will also be possible to have the “listen in” voice stream recorded to a cloud service.

Contacts sync
In the GroupTalk web admin there is a New section where you can add contacts (name and phone number) and then the contacts will be synced to the users Contacts on the phone (separate from GroupTalk).

The purpose of this feature is that in an organisation you might have a list of contacts such as travel agency, emergency, support, etc. that you want all new employees to have access to automatically. By using the contact sync in GroupTalk you can easily manage this list of contacts centrally and it will always be up to date for all the employees.

Remote provisioning of GroupTalk user accounts
The GroupTalk app settings and user credentials have been separated out to facilitate large scale deployments using MDM (Mobile Device Management) solutions.

Location History in web admin

A “breadcrumb trail” feature that show the movement of a specific user during a defined historical time interval is available in the web admin.

This feature requires that the location license is enabled and obviously that the user has been informed and approved the use of location services.

The picture above shows “Van 27” during the time intervall 11:56 – 12:12 on April 8, 2018.

By moving the mouse along the route (in the web admin) that the vehicle has moved you can see at what time the vehicle passed different points including the speed. The van stoped by Grand Hotel in Stockholm at 11:54:12 to make a delivery.

GroupTalk for iPhone and iPad 3.2.5

This release has a handfull of new features to improve the user experience of the GroupTalk app on iPhone and iPad. It is always a good idea to make sure that you have updated to the latest GroupTalk app release.
Channel next / previous hardware button support
The hardware button support is useful in combination with for example AINA bluetooth RSM or PTT phones that have dedicated channel next / previous hardware buttons.
End private call or end scan by pressing a channel change button
The ability to end a private call by pressing a physical button on for example AINA bluetooth RSM can be more convenient then ending the private call by pressing the “end call” button on the screen in the app.
Split view support for iPad
This is for iPad users that like to multitask and allows the GroupTalk app to be used on for example a third of the screen while the other two thirds of the screen is used for some other productivity app.
Incoming transmission alert sound with volume setting
This new setting adds an alert sound and vibrate before a received voice transmission is played (if there has not been a conversation during the last 30 seconds). This feature should be enabled by most users to alert you on an incoming transmission and improve the PTT user experience.
Text to speech channel announcements setting
This new setting will speak out the name of the channel / PTT Group that you have changed to using a next / previous channel hardware button. When receiving a private call the name of the user initiating the call will be announced before the actual voice transmission is received.
Start and stop sounds volume settings
A user can set the volume for the start and stop sounds part of a voice transmission. This is convenient if you for example switch from a RSM to a wired headset and might find the start and / or stop sounds to be too loud or too soft.
