Good morning everyone.
When calling a number with Zoiper from my android phone (Note 10 plus Samsung with Android 9) I seldom (not always) get that error.
The called person sees I tried to call him and calls back, so the phone rings, but after one ring the call is disconnected.
I have the same VOIP provider configured with Zoiper on the mac and the error didn't ever arise on the mac, so I guess it's something related to the android version of Zoiper.
I even tried other clients for Android and the voip account works fine, but I'd like to fix the issue and stick with Zoiper.
Any hint?
Thank you and have a nice day.
