I amusing a voip soft phone, a variaty of x-lite (mynetfone). The network system is behind firewall but without proxy. The x-lite can connect to serevr on window (boot to windows), but can't coonect when started at the win2000, a guest operation system on VMWARE server (on FC6). The softphone client uses port 5060 for in/out. Under the same network system (behind firewall without proxy), when xlite cann't connect to the voip server(mynetfone) when started at a guest OS (win2000) of vmware-server on FC6, while it can connect to when started at window system alone? On FC6 linux, the skype, twinkle are both working ok, I use twinkle to connect the mynetfone server, but there is difficulty to configure microhphone on llinux. Home someone could show me tips Best Yuandan
