Maybe I missed something, but that is from my SPA, just compare it with your settings. Also forward ports 5060-5061 and 16834-16842 to ip of your spa (UDP). Disable firewall when test it and DMZ part of router forward to you spa ip to be on safe side. To receive call forward port 5060(UDP) to your PC ip with softphone.
Please tell me when you downloaded it.
Thank you.
