MBS( "TAPI.Initialize" )




Returns OK or error.


Initializes the TAPI interface.
Must be called once before any other TAPI function.
This loads the TAPI DLLs and initializes the drivers. Depending on your driver, it may cause some initialization code to run, which can take a while, e.g. to find the base station for the phone system in the network.

If your TAPI drivers are 32-bit only, it may or may not work in 64-bit.
