Hello,
I need to prepare two kamailio instances accessing the same mysql db.
They will write to different location tables so i use function calls like these:

Server1:
  save("k1_location");
  lookup("k1_location");

Server2:
  save("k2_location");
  lookup("k2_location");

This is working fine.

However, checking db, I can see there is also a table called location_attrs and I am not sure what is its purpose (is this documented?).
Anyway, I suspect I should also set a separate copy of it for each kamailio instance, but I am not sure how to do it. 

Regards,
Takeshi
