After each call, within a few minutes you will receive a text message with the caller information. At this point, you will know after speaking with the caller if the call was relevant to your business. If the caller was asking about a service you do not provide or outside your service territory, simply reply back with the "1" in the text. You are marking the call "Not Relevant" and you will NOT be billed. You will have 24hrs to mark a call not relevant.
