[Stephen King's 1408] What was the voice screaming the numbers on the phone? Why those numbers?

Another illusion by the malevolent will of 1408. Because it's disorienting and terrifying.

The pairs of numbers always add up to 13, notably. This may be significant because, like many hotels, the Dolphin renumbers its floors so that its 13th floor is labeled 14-- so room 1408 is on the 13th floor. 1+4+0+8 also equals 13, and the temperatures the thermostat sets itself to also add up to 13 every time.

Edit: It's possible, based on the short story, that Room 1408 is a creature from Todash space much like It/Pennywise-- the short story describes both Enslin and the maid who went blind as having seen terrible colors. These are perhaps something like It's deadlights.
