Answer w/ co. greeting, dead air, listen for awhile, nothing, nothing, click, busy signal. I never, EVER say anything more than our co. greeting. I do not say hello. They're waiting for a live voice to respond again. So sick of this crap!
We're a doctor's office. Got two calls, a half hour apart, from this number. Answered "doctor's office, how can I help you?" Both calls gave no response, then hung-up.
I also work in a doctor's office and got several calls from this number. Same thing happened. I answered Dr's office, how may I help you?" and they hung up. Annoying. You would think dr's offices would not get all the spam calls, but we get them all ... people looking for donations, wanting to make us loans, telling us that it is time for them to do the regular service on our copy machine (we have no regular service set up). It is very, very disruptive.
