Yes, actually quite common, especially on "dry" circuits (those without 
talk battery).

Using their test set put current on the circuit, effectively (and 
temporarily) "sealing" noisy splices. This testing conundrum ("came 
clear while testing") led to interface devices that placed sealing 
current on the circuit.
