Calling station ID

[madal 30]

I have enabled the detail log in my freeradius server. It logs everything which is cool. However, in Calling-Station-ID it only logs the last octes as :
        Acct-Session-Id = "4FEE219C619400"        User-Name = "test at test.com"        Acct-Status-Type = Stop        Service-Type = Framed-User        Framed-Protocol = PPP        Acct-Authentic = RADIUS        Acct-Session-Time = 9        Acct-Output-Octets = 320        Acct-Input-Octets = 925        Acct-Output-Packets = 1        Acct-Input-Packets = 4        Calling-Station-Id = ".031"        NAS-Port-Type = Async        Acct-Terminate-Cause = User-Request        Framed-IP-Address = 192.168.1.20        NAS-IP-Address = 192.168.1.1        NAS-Port = 0        Acct-Delay-Time = 0        Acct-Unique-Session-Id = "537e68121f1931c8"        Stripped-User-Name = "test"        Realm = "test.com"        Timestamp = 1342054821        Request-Authenticator = Verified
How do I or where do i adjust this parameter sothat full IP address is logged in calling-station-ID ? I looked at detail file in  modules/detail but could not find the parameter
