Problems with freepbx GUI

hello

i have checked the issue and it seem that there is a full disk problem. the mysql log returns an error 28

And i see that the root filesystem is full

root@pc47 ~]# df -m
Filesystem 1M-blocks Used Available Use% Mounted on
/dev/mapper/vg_pc47-lv_root
50397 47966 0 100% /
tmpfs 1860 0 1860 0% /dev/shm
/dev/sda1 485 34 426 8% /boot
/dev/mapper/vg_pc47-lv_home
1823105 196 1730301 1% /home
[root@pc47 ~]#

Is it possible to do something that the recorded calls will be saved in another file system ?

Thank you
