[Freeswitch-dev] Freeswitch SBC register account

Hi all, I have one idea in Freeswitch SBC as: + I used Freeswitch as register proxy, in Freeswitch, it forwarding register message to kamailio and receive authen status. + In this case, FS action as a UA, and kamailio as a registra server. If user authenticated, FS store user infor in internal database, if not, it pass authen status to real UA. + i have research alot and do not know how to do this. Hope every one can help me to do this, i am new in FS, and new in FS module too. Thank all in advance   ThanhT
