[Serusers] WARNING: rtpp_test: can't get version of the RTP proxy

Im following "Getting Started with SER" and I'm stuck on the chapter about nat traversal Ive tried both methods, currently im working on rtpptoxy. the exact errors I get when i try to make calls from behind NAT are: 0(1731) WARNING: rtpp_test: can't get version of the RTP proxy 0(1731) WARNING: rtpp_test: support for RTP proxy has been disabled 0(1731) ERROR: force_rtp_proxy2: support for RTP proxy is disabled i have compiled and installed rtpproxy, and made sure the permissions were set. bmy bin # ps ax|grep rtp 1714 ?
