From interviews with Roger Waters, on the subject of <em>Money</em>, found at

Here is what Waters said about the sounds created for <em>Money</em>:
"The effects loops at the start of the song were re-recorded in the studio and this took a long time. Each sound had its own loop which we had to measure, using a ruler, to keep it in time. There was a tearing paper sound, a telephone Uni selector from a sound effects tape, bags of cash literally being droppedThere on the studio floor and a cash register ringing. The loop itself became the click. Once we'd got the loop they went out and played to it and I faded it out in their ears. It comes back once but that's just a happy coincidence, it's actually not quite in time."
A telephone Uni Selector, the phone noise that Waters described as being in the special effect of the mix, can be described thus:
The SxS exchange simply handles each number one step at a time. When
the receiver is picked up, it is connected to a device called a UNISELECTOR
which is just a moving arm making contact with a selected point. The purpose
of a uniselector is to find a free BIMOTIONAL Selector. A Bimotional selector
is simply a two dimensional version of the uni-selector. You are ofcourse
given a dialtone when the uniselector connects to the first BMS. When the
first number is dialed, you are connected to another bi-motional selector.
The selector connected to is dependent on the number dialed. Each number
dialed connects you to the relevant selector until the telephone number you
are calling is reached. See the discussion at

In short, the best I can glean from Waters' own quotes is that indeed the dial tone noises of a payphone were included,along with the clanking cash registers, to reach their desired effect. It's simply wrong to say that a phone was not in the mix.
Hope that helps.
