Exactly, that is what i am doing. using ODBC with Mysql. My registration are saving in "sip_registration" table and i can get the IP location of each user (sip_host address). A perl script serving the purpose of fetching records from DB and knowing the IP location of callee and caller. But , i am trapped in "domain" structure of FS. I do not want to create two copies of a single user, like SIP number : 1000 with domain of FS IP-1 SIP number : 1000 with domain of FS IP-2 As both FS instance need to knwo if that user exists in their directory or not, which is depicted in terms of "domain" -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Centralized-SIP-directory-tp75...
