Service Access Points

A service access point (SAP) identifies the characteristics of incoming calls of interest to a connection-oriented client. By registering a SAP with a call manager or MCM driver, a client indicates that the call manager or MCM driver should notify the client of all incoming calls addressed to that SAP.

A client does not always register a SAP, for example, if it does not handle incoming calls. A client can register multiple SAPs with a call manager or MCM driver.
