In Oracle Communications Network Charging and Control (OCNCC) 4.4.1, Session Control Agent (SCA) is a highly available and scalable SIP transparent back-to-back user agent (B2BUA), redirect server, proxy server and registrar.
There is a known issue where SCA is not handling RE-INVITEs when CLI privacy is active, in one call scenario with the SCA function, certain calls are dropping out after about 30 minutes when the A party has CLI Privacy turned on.
The SCA function is unable to process RE-INVITES coming from the B-leg of a call where the TO header does not contain a numeric CLI of the original calling party (i.e the user uri is set to "Anonymous"). This will occur which a call is made to SCA (A-leg) where CLI restriction is enacted.
In this case the SCA function is acting as a B2BUA.
