I'm looking for an open source push-to-talk (walkie-talkie) software for Android, preferably with secure end-to-end encryption.

Seems like Jitsi declares that it has the push-to-talk feature, however I still wasn't been able to find how to enable it.

  • From Android to Android, right? (So a solution is not preferred but required to be for Android?)

  • Yes, Android is require. But we haven't been able to find any open source solution of this kind. Commented Sep 23, 2014 at 22:05
  • Personally, my current guess would be mumble… But I'm still searching as libs don't seems easy to integrate in other custom software. Commented Jul 7, 2016 at 13:20

You have multiple, only tangentially related questions that would be better served being posted separately. Answering one of them...

Any tutorials/docs on how to get Jitsi work in walkie-talkie mode are highly appreciated.

I just attempted to use this featured and determined that is works in the same way as the Skype PTT feature, which is to say it is just a glorified mute button, with inverse logic. It does nothing to address rapid call setup, which is also a necessary part of what has come to be considered a PTT service.

According to the Jitsi release announcement for version 2.2 (2013.04.30):

Adds “push to talk” functionality (quick unmute while pressing Ctrl+Shift+T).

So you place a call, click some mute button in the UI, then use the Ctrl+Shift+T shortcut to unmute when you want to talk. (Messages in the Jitsi mailing list archives suggest you can change the key combination used for this.)

    "that would be better served being posted separately" and elsewhere. Only the first paragraph of the question is on-topic for this site, and this answer, though helpful, addresses the off-topic parts.
