It would also mean you're not the not the only person experiencing this problem. Might be worth a Google search to see if anyone else has reported issues with these numbers.
A great resource I use is 800notes.com. You can report suspicious numbers and also query numbers you've called or answered to see if they've been reported by other posters. Now that more people have become aware of phone scams and either blocked or refused to answer calls from unknown numbers, it's likely that the scammers are finding new ways to reach their marks. I wouldn't put it past them to hack into the phone systems of legitimate companies/organizations and program those systems to "reroute" random incoming calls. Industrious little shits they are!
TT, I never suggested it was human error, it think it is a phone issue. Some wireless phones cache the dialing digits. It you switched it to "pulse" mode dialing pulses would generated on the "base" end, not the transceiver.
