[cisco-voip] VOIP Eavesdropping?

[Edward Beheler]

This morning, a user reported that she got a call from an internal extension on our system.  She answered it and was able to hear a conversation between the apparent caller and someone else, but they couldn't hear her and apparently hadn't deliberately conferenced anyone into the call.  Eventually, the 'eavesdropper' hung up and reported the call to me.

Phones are Cisco 7942's, running SCCP42.8-5-3S, CUCM System version: 7.1.3.32900-4.  Each phone only has one line associated, and those two lines aren't associated to any other devices.  Both lines are in pickup groups, but different ones.

Anyone had this issue before, or can suggest where to start looking?
