Anyone else today noticing that the 3CXPhone softphone not connecting with your VoIP provider? Mine has been working flawlessly for at least six months.... until today. (version 4.0.10858.0) None of my 4 separate VoIP providers that I normally have it configured with will register today. This same strange phenomena happened about six months ago. The solution for me is to change the default STUN server setting from stun.3cx.com to any one of the publicly available STUN servers. I just reset mine to stun01.sipphone.com and.... everything is working fine once again. I guess the 3cx stun server is down? I came here to see if others were experiencing the same problem but I was surprised to see that now one else seems to have noticed this issue... I suppose I'm in the minority of users who use the 3CXphone to directly connect to VoIP services.
