Routine Description:

This method is called by TAPI3 to get a list of static terminals that can 
be used on this address. If our list is not empty, just return the list. 
If our list is still empty, create the static terminals and return the list.
Derived class can override this method to have their own terminals. Locks 
the terminal lists.

Arguments:

pdwNumTerminals
    Pointer to a DWORD.  On entry, indicates the size of the buffer pointed 
    to in ppTerminals. On success, it will be filled in with the actual number
    of terminals returned.  If the buffer is not big enough, the method will 
    return TAPI_E_NOTENOUGHMEMORY, and it will be filled in the with number
    of terminals needed. 

ppTerminals
    On success, filled in with an array of terminals object pointers that are 
    supported by the MSP for this address.  This value may be NULL, in which 
    case pdwNumTerminals will return the needed buffer size.

    
Return Value:

S_OK
E_OUTOFMEMORY
TAPI_E_NOTENOUGHMEMORY

Routine Description:

This method is called by TAPI3 to get a list of dynamic terminal guids 
that can be used on this address. It asks the terminal manager for the 
list of guids and returns them. Derived class can override this method 
to have their own guids.


Arguments:

pdwNumClasses
    Pointer to a DWORD.  On entry, indicates the size of the buffer 
    pointed to in pTerminalClasses. On success, it will be filled in 
    with the actual number of class IIDs returned.  If the buffer is 
    not big enough, the method will return TAPI_E_NOTENOUGHMEMORY, 
    and it will be filled in the with number of IIDs needed. 

pTerminalClasses

    On success, filled in with an array of terminal class IIDs that 
    are supported by the MSP for this address.  This value may be NULL, 
    in which case pdwNumClasses will return the needed buffer size.
    
Return Value:
