EPM, unreachable until rebooted?

After using ZTP and EPM to provision a S700 for ext 123, it’ll grab the config and an IP, but EPM shows “5060 unreachable”. Only after reboot does the phone become reachable and routable for calls. Is this normal to have to reboot after provisioning?

cat /var/log/asterisk/full | grep 123
