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.

GroupTalk for Android 3.2.3


Wideband audio is the most noticeable news in this update.

Additional new features and improvements:

  • Support for Android 8.0 Oreo
  • Incoming transmission sound is a new setting that adds an alert sound and vibrate before a received talkburst is played (if there has not been a conversation during the last 30 seconds). This feature is particularly useful if you use a phone for PTT without any PTT accessories. This is a feature that actually has been asked for by many of our customers. Please check it out and provide us with your feedback.
