Is it possible to set asterisk's VoIP authentication to be based on EAP-SIM auth of freeradius?

Hi all, I want to make initial VoIP authentication process from asterisk server to be based on EAP-SIM authentication of Freeradius server (so it will be not necessary to insert account datas in the asterisk database). Is there any way of doing that from Freeradius? Or at least, is there any way to sync the EAP-SIM data on Freeradius to asterisk server? thank you -- Best Regards,
