[Serusers] aliases

I am coming over from OpenSER because I ran some tests and found SER to be much faster. There are some things that are new to me that I imagine are easy to do. I have a working config with the 12/22/06 development snapshot of 0.10 but I would like to lookup aliases to redirect inbound calls to another domain. I filled in the domain table and the uri table with a user and I looked through the sample config but can't seem to get it to work. I have also loaded the domain module, then the uri module, then the avp and avpops modules (among others). Any idea what I might need to put in my route? This doesn't seem to work (stolen from ser.cfg.sample): if (lookup_user("$t.uid", "@ruri")) { setflag(1); route(1); break; }; Thanks!
