1.1.0 is way too old :-) . If you try it right now, I recommend using 
3.1.x, I have tested it a SIPit and location was working fine.

Core and SIP routing are also ok. To my knowledge the permissions module 
has a too small column size in database address table (on my todo list 
to fix in this devel cycle). Probably the same is with lcr module.

Being that old, I cannot remember if there were other issues. If you 
want to continue with this one, run it in debug mode, also enable mysql 
query logs and try to figure out what was wrong there. Then maybe there 
was a fix for that. Anyhow, iirc, there was an issue with storage of 
ipv6 address in one of the location fields, probably not done in 1.1.x 
at all since was done more recently.

Cheers,
Daniel
