What do we need to make the backup domain controller perform actively if the domain controller set down in Windows Server 2003 on AD network? Any ideas?

I was attempting to assimilate Office Communications Server (OCS) 2007 to a current SIP (Session Initiation Protocol) infrastructure through its own proxy. Configuring correctly the Routing and Host Authorization options, I was able to call using the OCS 2007 client to SIP clients. But the problem is I was unable to do the reverse way. I cannot make a call from my SIP client to OCS 2007 client. What is your solution to this?
