| Platform SDK: TAPI |
Call data is a variably sized buffer implemented by some service providers in order to accumulate information about a session and make that information available to all applications which handle the session.
Call data is most commonly used in a call center environment, where access to information such as an IVR input of account numbers may be needed by several agents.
Not all service providers support use of this information.
