The spam calls have been getting much worse. I contacted support, who suggested I create spam blockers and enter each number individually. Been there, done that. It is a useless task. The spammers just keep changing their phone numbers. It is not MY job to spend an hour a day signing on to my account and entering phone numbers. It is hugely distracting from my production here at the office. I have received at least 6 "NO DATA" calls this morning between 9-11 am. It's up to COMCAST to listen to all their business voice customers and come up with the software to avoid this issue. I use NOMOROBO at home, and even that has begun to fail as more robocalls are getting through. DO SOMETHING NOW!!!
