Hello again, Thank you very much for your valuable input!
Now my problem is that when dialing any SIP URI via my Snom phone, the sipX just returns "404 Not found". I can clearly see via Wireshark that sipX is not doing any lookups on the domain name part of the dialed URI or proxying the request at all. So it is not really trying to find my target. What am I doing wrong? As far as I understood I do not really have to configure that much (the NAT options in "Internet Calling" are activated, internal domain and internal subnet is configured and no trunking as you said). Do I have to enable some kind of dial plan for dialing out via SIP URI or is there something else blocking the proxy from doing its job?
