I don't see why I would need to punch holes in my firewall to make an outgoing call. At this point my goal right now is to call my phone and hear audio go both ways I'm concerned with taking calls yet that will come later. I strongly suspect it's some kind of networking issue am I missing a port in my forwarding? I also found issues with incompatible codecs somewhere in the pipeline so I made sure FreePBX and X-lite were setup to support ULAW, ALAW and GSM. I'm assuming this DMZ setting opens all ports to that machine but I can't be sure and I didn't leave it there for long so it's possible my router didn't have time to respond to the changes. One-Way or No Audio During Calls If you are noticing that calls connect, but there is no audio flowing in one or both directions, the most common cause of that is that the audio data is being routed incorrectly after the call is established. In both cases I could connect but still no audio in either direction.

However, only when I use x-lite out of network, phone is ringing and connected but no sound and then phone end-up after a few seconds. If the x-lite in LAN behind router all good even using external public IP address. I also tried using the DMZ option that my router provides to put that virtual box on the DMZ. When I use x-lite direct connect to the system by SIP. I have tried forwarding ports 5060 UDP and 10001-20000 UDP to the freePBX virtual box with no success. When googling this most of what I find has to do with NAT not being configured properly. The phone will ring however I can't hear audio in either direction.

I'm using X-Lite on the windows 8 machine to make calls to a MetroPCS cellphone. My windows 8 host is connected to a typical home wireless router. Combining voice and video calls, Instant Messaging and presence management in an intuitive and familiar interface, X-Lite helps you seamlessly transition from a traditional hard phone environment into the world of VoIP. I have FreePBX running on virtualbox on a windows 8 host the network adapter is set to bridged and I have assigned it a static IP address. X-Lite softphone is the markets leading free SIP based softphone available for download.
