Since we started to use a softphone on the company laptops we decided to solve the issue of the connection outside the office with a vpn connection that I have to say that works prety good. But I have to say that the tunnel feature looks really nice for that comunication issue. 1.Now can this be done with the X-lite or there is another softphone that works better with this feature? 2. You can set the ip on the PBX as the IP that listen to the internet. (Public IP)? That is for avoid the forwardig ip.
