4G Keypad Intercom Development   'Have you got a keypad intercom yet?' Well yes we do! It only took 8 years. We designed the simple 1-button 4G intercom with a keypad expansion in mind. In fact we had a non-working mock up of the keypad unit around the same time we launched the 1-button version. In practice though it took quite a few changes to the basic design which we will examine here. Our chosen keypad features a die-cast metal enclosure designed to be mounted with screws through the front panel. Having screws appear on the front panel looks a bit...

Issue: Double output pulse on dial-ins On  23/10/20 Hutchinson Telecom appear to have changed the way they reject calls to our portal. Instead of denying access to the number (which subsequently played a message stating you not able to place the call) they now perform a hard reject.

The Fix To resolve this issue, we store in the database the time of the last call from...
