Speaking to the former tenants of Calthwaite Hall, you're probably not far from the mark. Such 'speaking instruments' must surely have halved the work of the butlers and staff: being instructed directly and only making one trip to 'er Ladyship' rather than looking at the flag, walking upstairs, then going for what was required.

I need to check in Herbert G. White's 'Telephone Erection and Maintenance' but I'm pretty sure some sets were made specifically to use existing annunciator wiring without too much modification.
