Write error on RTP socket usually indicates an incorrect network setup, for example trying to use a source address for IP packets which isn't bound to any local network interface (especially if you're sitting behind NAT), or local iptables rules rejecting outgoing IP packets, or missing IP routes to the destination. Perhaps post your network setup and the CLI arguments to rtpengine you're using.
I use VPS from DigitalOcean. Likely no NAT. Only one public IP, and one domain name used (whdd.org). Exactly the same situation was with Amazon VPS behind amazonish NAT. My configs are here: https://github.com/krieger-od/webrtc_kamailio_etc (only kamailio.cfg and modules.cfg are used, kamailio*.cfg are not). Also there you can check command line used to run rtpengine. To put it there, it is /home/krieger/rtpengine/daemon/rtpengine --interface=188.226.241.236 --listen-ng=127.0.0.1:22222 -m 30000 -M 35000 --foreground --log-stderr
Amazon NAT is exactly why I've mentioned it, because on an Amazon system, if you don't use the --interface option correctly ($INT_IP!$EXT_IP notation), you get exactly these kinds of write errors that show in your log.
But these configs and this CLI line don't match the logs you posted earlier. Is it also write errors you're getting with those?
