Purpose
SAPphone provides an RFC interface which is used to connect external telephony software to SAP Systems. Third-party manufacturers can program a direct connection to the RFC interface or use the SAPphone Server delivered with the SAP System. The SAPphone Server works as a link between the SAPphone RFC interface and the TAPI standard interface defined by Microsoft for telephone integration solutions. If the SAPphone Server is used, manufacturers of TAPI-compatible telephony products do not have to program an individual connection to the SAPphone RFC interface.
The following graphic shows the components involved in connection via the SAPphone Server:

Implementation Considerations
See
Architecture of the Telephony Connection.Features
SAPphone Server 2.5 supports all the basic telephony functions and call center functions of
SAPphone. It is downwardly compatible, meaning that you can use it with SAP R/3 version 3.1I and higher. Predictive dialing is not supported by the SAPphone Server.
