the cases: The app registered on a PTT channel Server sent a push notification (using a PTT's token) The app receiving the notification process it and open the link to server to read the data stream the user tap the UI (app's or API) button to send voice message works as well Everything works good until the user is unload the app from the memory but keeps the channel active, in this case the App can't open a network connection to the server side to read or write the data stream, even the user tap the API UI button to send a message.

Hello, Do you recommend to use Push to Talk for Voip apps ?

I was just watching the Enhance voice communication with Push To Talk WWDC22 session video and was wondering (a few questions) -- (1) (when) will you be making the demo app available that was shown at the beginning of the video? (2) There was some detail given regarding the new APNs push type ("pushtotalk"), but it was unclear to me if that's something I need to handle manually, or if those will be sent automatically when I do channelManager.requestBeginTransmitting? (3) How does the audio data itself get routed around? Is that handled by the system between the requestBeginTransmitting and stopTransmitting calls? Or somehow part of the APNs payload? Or something we must handle? Thank you! thanks!!

Can you please post the sample code?
