I modified the openserctl script to give more output:

400 table (aliases) not found
error: 400; check if you use aliases in OpenSER

on `openserctl ul add 11112223333 at etcvoip.net sip:18122228203 at etcvoip.net`

I traced this message back to the ul_show_contact function in ul_fifo.c. 
Everything is fine until it gets to line 573, where it calls 
fifo_find_domain, which sets d=0. Then, in line 575, the error message given 
above is returned because d if now false.

static inline void fifo_find_domain(str* _name, udomain_t** _d)
{
	dlist_t* ptr;

	ptr = root;
	while(ptr) {
		if ((ptr->name.len == _name->len) &&
		    !memcmp(ptr->name.s, _name->s, _name->len)) {
			break;
		}
		ptr = ptr->next;
	}
	
	if (ptr) {
		*_d = ptr->d;
	} else {
		*_d = 0;
	}
}

I'm not a C programmer, so I don't really understand what's happening here, 
but it appears to be looping through a list to find a domain, checking to be 
sure their lengths and values match. It keeps looping until it finds one, and 
then quits on the first one. It appears that ptr doesn't point to anything in 
my case; it fails the next if, setting the passed-by-reference d to 0, 
leading me to think that it hasn't found any domains, or couldn't get a 
domain list in the beginning. What does this "ptr = root;" mean?

I then tried running `openserctl domain show`, only to get:

500 command 'domain_dump' not available

Now, I checked the actual database openser.domain table, and my domain 
appeared correctly. I am also loading the domain module on openser startup.

Any ideas? I realize this is getting awfully deep into code, but I hope 
someone can help. It's probably a simple error on my part. Thanks in advance.
