GATE CALL IN

When I have a guest coming to my unit I call the phone number for guest and a
recording comes on and states to CLEARLY STATE THE NAME OF YOUR GUEST
AND DO NOT HANG UP UNTIL TOLD TO DO SO. The last 3 times I called in my
guest and clearly stated their name and was told that I may hang up the phone now
it seems when my guest gets to the gate and shows their ID they are asked for my
address. When they hesitate or say Chatham O they refuse to let them in because they
did not know the unit number so then they tell them they have to call me and tell them my address. Does anyone else have this problem??????????
