Absolutely! Plug in two 824's and you have 32 extensions. Expand the second box and you have 48 extensions. The numbering plan and the intercabinet calling is zero, the trunks don't share, but you can work 48 extensions.

There's a saying "you can lead a horse to water but you can't make him drink". In Fidoland there's you can lead a horse's xxx to knowledge but you can't make him think".

Buy 2 of everything, or 1 TDA-1232 or a newer product with MSLC/SLC cards, but don't expect a miracle out of a fixed product. It's an 824 and I'm out of this thread.
