Oh contrare my dear Mart!
I have quite a few photos of them I have taken over the years...and they are all out the back on the ones I have encountered. They are generally ornate with rounded or more ornate tops - that rules them out for bedside tables when they have a door and a drawer. In addition, being from the true south...I have encountered many a one over the years. The door on this style doubles as a writing surface and the drawer holds the pens/paper/etc. There are different ones/styles out there.... The instrumental question here is "was the hole original"...then I say it is a telephone cabinet. If it wasn't...then I vote liquor cabinet.
This is a more ornate one I found online...and if they had posted the innerds I bet my next piece of banana bread that it has the hole out the back!
This this one...American Made
http://www.telephonecollector.info/collectionsite/specialty_items/stickcab.jpgAmerican Made One: This is a very special candlestick telephone cabinet, designed to "hide" the phone from view. The back slides up so that the connected phone can be placed in the cabinet with
cords exiting the back. The phone sits on a slide-out shelf. To the side of the phone is a pocket for phone books. Below the phone is a drawer for storing desk items. There is a decal in the drawer with the name of the manufacturer, Imperial Furniture Company, made in Grand Rapids, Michigan. There is also a small stool that fits between the legs of the desk. This one is very tastefully ornate with some door design and other subtle features, suitable for most any home decor. I bought this in Las Vegas in an antique store in 1990.
