They replaced all the old POTS phone with VoIP phones, which are basically digital. Except they look pretty much just like the old phones. And sadly, have the same crappy user interface. Make a mistake dialling, and you have to hang up and start over. There's no delete button – why not?
It's skeumorphism in all the bad ways – they imitated the analog so slavishly that there are very few benefits to being digital.
And what genius decided to make the outside line 9, as in hit 9-1-626-867-5309 to dial an outside number. No, no one is ever going to fat-finger 911.
