My line just started beeping 10 times as well. I tried *99 and a voice says that the service is not available on this line. In the past, I asked them to disable the voicemail. Any suggestions besides getting on the phone with Comcast?
Sorry for the inconvenience. At the present time we do not support business services on the forums. We have a dedicated Business service tea available to assist you. However I have reached out to Business services and will have someone contact you and they will be able to access your account to figure out what is going on with your voicemail.
