There are a number of ways that Caller ID can deliver erroneous results. If your wife's employer has a PBX (a kind of business phone system), then the PBX must send valid Caller ID to the local phone company. If her employer and your home phone use different local phone companies, the one company has to hand off the Caller ID data to the other.

A glitch in any one of those steps can cause you to get garbled Caller ID data.
