I’ve done a completely fresh machine using the config from the GitHub issues using Amazon Linux 2 and registration is sending. I’m unsure what is varying, but I think I’ll rebuild this whole thing as an Ansible playbook anyway so I can redeploy quickly.

Here’s the bash history for anyone curious: 1 yum install -y gcc gcc-c++ bison flex make ruby-devel git 2 git clone https://github.com/kamailio/kamailio.git 3 cd kamailio/ 4 make include_modules="app_ruby" cfg 5 make all && make install 6 cd /usr/local/etc/kamailio/ 7 ls 8 vim kamailio.cfg 9 vim /etc/systemd/system/multi-user.target.wants/kamailio.service 10 systemctl daemon-reload 11 systemctl start kamailio 12 tail -f /var/log/messages 13 ls 14 mkdir /usr/local/etc/kamailio/dbtext 15 cd /usr/local/etc/kamailio/dbtext 16 ls 17 vim uacreg 18 systemctl restart kamailio 19 tail -f /var/log/messages Mar 26 14:18:00 ip-10-0-0-3 /usr/local/sbin/kamailio[17873]: ERROR: <core> [core/resolve.c:1698]: sip_hostport2su(): could not resolve hostname: "sip.example.org" Mar 26 14:18:00 ip-10-0-0-3 /usr/local/sbin/kamailio[17873]: ERROR: tm [ut.h:309]: uri2dst2(): failed to resolve "sip.example.org" Mar 26 14:18:00 ip-10-0-0-3 /usr/local/sbin/kamailio[17873]: ERROR: tm [uac.c:452]: t_uac_prepare(): no socket found Mar 26 14:18:00 ip-10-0-0-3 /usr/local/sbin/kamailio[17873]: ERROR: uac [uac_reg.c:1181]: uac_reg_update(): failed to send request for [12345678] If anyone can help find the issue I’d be very interested, however it looks like issue is package/config somewhere rather than kamailio.
