Dear Zoiper community,
i have an issue on my Sony Xperia z3 Compact D5803 with Android 6.0.1 Marshmallow. I am using Zoiper 1.38 for Android and a Fritzbox 7360 SL with firmware version 06.30.
I have set up a IP telephone on my fritzbox and within zoiper. Incomming calls are working perfectly fine. But when I try to dial any number the number disapears from the dialpad display and nothing else happens.
While writing this comment, i tried also my Sipgate (DE) account. Here the same issue occurs, when i try to dial any number.
Is there any configuration i can check?
