You would think that at this time in our lives, that an elevator phone would be a no brainer. Hell for the less then the cost of most elevator phones, you can get a smart phone that will almost wipe your @#$#. Elevator phones should just work, There should be no issues with these units. I kind of like the janus idea where you call and they take care of the rest. I usually don't deal with phones, but I can see where taking a couple of hours to read the manual and try to set the damn thing up can be frustrating to an elevator mechanic that already is overburdened by the sheer number of units the big companies are expecting him to take care of in 1/2 hour increments, all in the name of more profit for the share holders. uggggghhh
