hello there, I am new to SER, just want to configure it with two NIC interfaces (for global network. calls from external network (global network) should be routed to a sip-endpoint in internal network. and I need rtp proxied with it. I have tried but rtpproxy is crashing or SER is crashing. can some one please tell me the stable version of SER or rtpproxy to use and can some one please send me his configuration file working in a similar schema. *sip-endpoint in internal network is not registered on the SER. thanks Atif
