I am using OpenVPN to access my internal network. I have FreePBX for my SIP phones. I have a soft phone on my cell phone when I am on my WiFi the soft phone works great. When I leave WiFi and go to VPN I can connect to my PBX. I have audio going from my soft phone to any phone on my network. I do not have any audio going from my in office phones to the soft phone. I can call from soft phone extension to any internal extension and I can call from internal extension to my soft phone extension. I have my internal network as 10.0.0.0/24 and my VPN network 10.8.0.0/24, I have both in my PBX as trusted networks. I have the OpenVPN setup to NAT the information. I have googled the for days now, and all I have come up with is that I should buy the VPN option on FreePBX. This will not work as I have to run software on my phone through the VPN and use the soft phone at the same time.
