Hi list. I try to deploy cluster FS by using "ODBC in the core". But i have some problem when deploy: 1. I deploy 2 FS share registration ( by config odbc-dsn in internal profile). With default config: User 1001 registers in fs1: 10.2.48.194, user 1003 registers in fs2: 10.2.48.243. I show sofia status profile internal and see to registration: Call-ID: d3298837aa18ac2bOGYyNTYyZGJjNzcyNzNhNDA3MTI0MmY4MmMzOWFkZDU. User: 1001@10.2.48.194 Contact: "1001" <sip:1001@10.2.48.184:42064;rinstance=22b332e0ef7c7fc1> Agent: eyeBeam release 1003s stamp 31159 Status: Registered(UDP)(unknown) EXP(2010-04-16 11:26:47) Host: FS1.voip.vn IP: 10.2.48.184 Port: 42064 Auth-User: 1001 Auth-Realm: fs.vn MWI-Account: 1001@10.2.48.194 Call-ID: NzFiZmQxM2FlZDdmZjU3NTk4NjY4NmIwOWQ4NTcwZDI.

It likes because user 1001 calls 1003@10.2.48.194 while user 1003 is registers 10.2.48.243. I read in list that can call between FS with odbc in the core. Do i miss config something ? 2. I have read some comments with 2 FS, we need to config DNS-SRV for load balance between them. But I wonder how gateway connects with fs by load-balance SIP trunk? Tks for help.
