Re: [SR-Users] Kamailio 3.0 cann't access the RTPProxy

Hi Daniel, Does the logs have any hint for what's cause of the issue? I didn't include the user list in the previous email since logs have the actual IP info. Thanks in advance!

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. Hopefully will get more hints about what happens.
