i will be aborad for 3 months an will call into the home phone net over my spa9000 system. I have a wrv200 router and we are using nat translation. Which ports do i have to open for registering a softphine like x-lite to the spa9000? I will try this directly over the web because i the vpn-tool of the router is not working.
Has anyone tried this yet?
Thank you for your help!
