Guys, I have installed ZoiperBeta app in November 2016 - it was amazing! Almost one year of excellent work! but now I have changed my phone and had to install it again. I'm going to cry with tears! It is not working now. The network settings related to NAT disappeared. And it is very important for me because it doesn't work without it. I can connect to server, make a call but there is no voice. Where can I get build from November 2016? I'm ready to pay for it!!!!
Which NAT configuration options are you searching for ?
Good morning Juunior,
You may use the STUN server or your own STUNserver, which will do the settngs for you.
Or you setup port forward of the port used by the Zoiper, most likely 5060, but please check your settings.
