Hey, I got a Windows 7 PC with 3CX Client and a headset. I want to connect this to a Windows 2012 Server virtual machine with 3CX Phone System 12. The PC and the VM can ping to eachtother, but the client can's see the server and the server can't see the client. When I do the command: arp -a I see both IP's listed in the table. Windows Firewall is shut down so that should be no problem. There's something strange. When I have the 3CX server on my Windows 7 PC, it works. So i think it's a VM problem. The network is setted on Network Bridge Adapter, so there's no NAT involved. Anybody has the answer?
