Hello, I'm not familiar with coding, however attached is the man for the writev on the system. Help this can provide some additional information.

Does it mean nathelper has issue to send the request to RTP proxy first or nathelper doesn't receive a response after sending a request to the rtp proxy? 0(27429) ERROR: nathelper [nathelper.c:2457]: can't send command to a RTP proxy this error is printed when write to socket fails. Do you have any firewall running on the system? Is the user under which kamailio runs allowed to write to sockets? There's no firewall on the system, and I run the kamailio as root, root 26310 1 0 02:24:19 ? 0:00 /usr/local/kamailio-3.0.2/sbin/kamailio -f /usr/local/kamailio-3.0.2/etc/kamail You can edit module_k/nathelper/nathelper.c and replace the line 2457 with: LM_ERR("can't send command to a RTP proxy (%s/%d)\n", strerror(errno), errno); Recompile and reinstall.
