Although the FO has primary responsibility for initiating calls to the DDS to transmit
            information essential to the disability determination, there may be occasions when
            the DDS will call the FO in title II and/or title XVI cases. Such requests will usually
            pertain to information available from the E/R, the claimant's compliance with DDS
            requests, help in locating a medical source, or contacting someone in a position to
            help the claimant. If the FO cannot comply immediately with the DDS request because
            the E/R has not been received or a necessary contact cannot be readily made, diary
            the request for immediate telephone reply to the DDS when such information is available.
            Follow-up with the source of information to assure expeditious DDS processing.
         
         The DDS will inform the FO by phone of capability development as soon as the DDS becomes
            aware of it.
