[Serusers] Simple Request/Response Forwarding

Hello everybody, i'm new to SER and try to write my first config file. Since my english is not that good and i dont have much time, i want to minimize my reading of SER tutorials. This is my VoIP - test enviroment: UA(private/local IP) <-> (private/local IP)SER(public IP) <-> (public IP) VoIP - Provider I want SER to simply relay/forward all incoming and outgoing calls. I dont want that SER should have a SIP -domain, no authentication or registration. RTP - Streams should also be forwarded over the Proxy. No my questions: What is the simplest way to implement this? As far as i know i need the rtpproxy module. Do i need the nathelper or any other important modules? I also figured out to use the mhomed option. Has someone a sample config file for such a scenario? Any Documentation in German for the config file? Thanks in advance and any Help & Tipps would be very appreciated. _____________________________________________________________________ Der WEB.DE SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen! http://smartsurfer.web.de/?mc=100071&distributionid=000000000071
