Broken english- possibly hispanic voice qualities. Called wife, who knows how they got the number. Called back to ask if they would leave us alone, person answering said the company was extended warranty. Asked to be put on DNC list. CenturyLink twice said they could not find our account when trying to pull up. Wondering if our service is being routed through another router since VOIP is capable of that. Speculate that these people could be calling our number to get tacit permission to route their discount calls through our account (read about this before).
