An old telephone with a cord for the receiver is a dangerous object! Especially in fiction, when a) that cord can be absurdly long for no practical reason, and b) characters are easily distracted and ignorant of the world around them when they become engrossed in the phone conversation.
This results in the phone user, or more often the people around them, finding themselves caught in a messy web of tangled phone cord quite easily. Can occur if the character likes to Walk and Talk, slowly encasing themselves and any innocent bystanders as the conversation goes on. Of course, they could just as easily fall into the phone, and if a villain is short on rope a phone cord is the surprisingly popular alternative to tie up or strangle a victim.
Sadly, Technology Marches On, and the advent of cordless phones and cellphones are the Trope Breaker for this trope. This can also add to the trope though; if a character is used to using cellphones and has to rely on an old phone in an old building etc, they would invariably struggle with an unexpected cord.

- One of the inevitable results of old-style telephone receivers, where the handset was permanently attached to the receiver by a coiled cord, was how quickly the connecting cord ceased to be a neatly organised smooth coil. It would inevitably tangle, snag, knot, loop back on itself, and tended to somehow double over on itself, until the connecting wire between handset and receiver was effectively half its original length. Anyone picking up the handset to such a phone would drag the whole thing up off its table and find it swinging in the air. Left-handed users soon found that the arrangement favored right-handed people — both in the direction of coiling, and in the way the headset was meant to be returned to its rest with the connecting wire on the right-hand side. Any old-style phone regularly used by left-handed people would unravel its coils twice as fast (the natural tendency being for a left-hander to return the handset to the rest with the coil-connected end on the left.) Any household with both left and right-handed people would discover their shared phone suffered from Garden Hose Syndrome — it became an utter tangled mess very quickly.
