Are TAPI applications and service providers backward or forward compatible?
There are three components of TAPI that determine the version being used. The first component is the operating system (see question 2), which is backward compatible but not forward compatible. If you are using an operating system that only supports TAPI 2.0 then applications and TSP’s that only support TAPI 2.1 or later will not run. However, if you are using an operating system that supports TAPI 2.0, and the application and TSP both support TAPI 1.4 then the application will run properly. The next component that determines the version is the TSP being used. When a TSP is loaded by TAPI it negotiates a range of versions that it supports. For example, a TSP may support TAPI 1.3 through TAPI 2.1, or it may support only TAPI 1.4, or it may support any other contiguous range of TAPI versions. The TSP can only be installed in an environment that is supported by the TSP. A TAPI 2.1 TSP can not be installed in a TAPI 1.4 or 2.0 environment. The third component that determines the version is
