After starting to paste the kamailio.cfg snippets, I noticed I was using
route(SIPOUT) instead of route(RELAY) for the aliases. Switching it to
RELAY fixed it. What is the difference between the two? Does SIPOUT
only work for devices registered with Kamailio?

Assuming you haven't changed the default config, SIPOUT only handles routing to foreign domains:

# Routing to foreign domains
route[SIPOUT] {
   if (!uri==myself)
   {
      append_hf("P-hint: outbound\r\n");
      route(RELAY);
   }
}

If your alias is still a local URI, SIPOUT would just ignore the message and exit the block.
