[Freeswitch-users] multiple inbound trunks

Hi all; I need to run a switch will handle calls from 30 different provides ( some of them have more that IPaddress as originator ) to two gate. 30 SIP providers =====> FS ==> 2 SIP gate cos there is no registration, first way is to open them in acl.conf.xml. but I like to know if there any other way ( for incoming trunks without registration ) to open / accept there calls and distinct them before dial plan to route them better and of course easily log parsing! simply management is there any idea? tnx
