change the usrloc db_mode in your kamailio.cfg on both kamailio server.

mode 2 will store the location Data to your mysql server.

modparam("usrloc", "db_mode", 2)

2 - Write-Back scheme. This is a combination of previous two schemes. 
All changes are made to memory and database synchronization is done in 
the timer. The timer deletes all expired contacts and flushes all 
modified or new contacts to database. Use this scheme if you encounter 
high-load peaks and want them to process as fast as possible. The mode 
will not help at all if the load is high all the time. Also, latency of 
this mode is much lower than latency of mode 1, but slightly higher than 
latency of mode 0.
