Who maintains Call States?

[Mohit]

Hi Friends,

Can any one tell me that in TAPI, who maintains the state of the call?
I mean, when an incoming or outgoing call is made using TAPI Application
then the call is passed from various call states like, Offering, Connected,
Idle, Diconnected, etc. So, who maintains these call states, TAPI
Application, TSP, TAPISRV or all of them?

Thanks,
Mohit

Mohit,
solely the TSP maintains the call states.
The TSP sends LINE_CALLSTAE messages to TAPISRV,
TAPISRV passes these messages to TAPI apps monitoring this call.
