Hello! I have installed 3CX Phone for windows 10 mobile on my phone lumia 720. I introduced all settings of the ip-operator (not 3CX). But the application writes "No registration". I talked to tech support operator and found that the application tries to be registered with the wrong password. Operator's answer was: "We receive authorization attempts with an incorrect password. The application 3CXPhone for Windows10 14.0.44619.0 - with an incorrect password" So, the application sends the wrong password. Please help. Thanks.
