Not sure about the phone but, as an aside bordering close to a tangential discussion, that radio in the lower right foreground looks like an RCA 26x-1 Chassis RC1014 AM/SW Radio, or some model similar that used the same chassis and housing.

My didn't get the back board with mine but looking at the radio in the Maltese Falcon image, the number of top ridges, the top side design and the antenna frame (showing through the opening at the top of the back board) match mine.
And the right front of the dial shows a gold box with the word "POLICE" over 170 (1700 KHz AM band) which would let Sam listen to police calls back then. The first image below shows that best.
