-/**
-Base implementation for virtual API declared in MCallBaseTSY.  This base implementation always returns KErrNotSupported and 
-it is therefore necessary for TSYs who support this API to override this in their CCallBase derived class.
-
-This function passes through a pointer to a heap-based CFaxSharedFileHandles object.  This object is instantiated by Etel but 
-a successful return of this function will pass responsibility for deletion of aFaxSharedFileHandles from Etel server to the TSY.  
-If an error code is returned from this function (e.g. KErrNotSupported) Etel maintains ownership of the aFaxSharedFileHandles and 
-is responsible for its deletion.
-
-TSY overrides of this function must correctly handle the cleanup of the aFaxSharedFileHandles object if they take ownership of it 
-which is implied when returning from this function with KErrNone.
-
-@publishedPartner
-@param aTsyReqHandle Handle to request.
-@param aFaxSharedFileHandles CFaxSharedFileHandles instance to be stored in TSY.

+Base implementation for virtual API declared in MCallBaseTSY.  This base implementation always returns KErrNotSupported and

+
+This function passes through a pointer to a heap-based CFaxSharedFileHandles object.  This object is instantiated by Etel but 
+a successful return of this function will pass responsibility for deletion of aFaxSharedFileHandles from Etel server to the TSY.  
+If an error code is returned from this function (e.g. KErrNotSupported) Etel maintains ownership of the aFaxSharedFileHandles and 
+is responsible for its deletion.
+
+TSY overrides of this function must correctly handle the cleanup of the aFaxSharedFileHandles object if they take ownership of it 
+which is implied when returning from this function with KErrNone.
