The table below shows whether a particular standard is supported in the OC SIP RA itself (Full), or if the standard may be easily supported by an application using the RA (Partial).
The SIP protocol was designed to be very extensible, so most SIP standards assume a basic SIP stack is available, and add extensions that can be implemented at the application layer.
The rapid pace of development in the SIP world means it is not feasible to support every new standard directly in the RA, and this is not necessary when they can be easily implemented by an application.
