After updating to iOS 11.2 I often have audio problems. I can talk for five minutes. Then it doesn't work anymore and I have to restart the iPhone. Then I can call again for 5 minutes and then I have audio problems again. I haven't changed any of the settings and have been using Zoiper for 1 year.

Thanks for help,

Good day!

Closing the app ( removing from memory ) is not enough?

Please let us know.

Running any other apps on the background that use audio?
