Hi, my account works fine when the app is open, but when I put my phone in stand-by, when I receive a call, the ringtone SOUND is very little. I can't hardly hear it....
How could I fix this ?
Try to use TCP transport for your account - your provider must support it as well or the account will not register. Afterwards disable the Force background option - the calls will continue to come because the TCP is better handled on iOS than UDP.
