Ending Phone Service - new number notification?

Thanks for reaching out to our Comcast Business Support Forums, danstewart. We can set up a temporary notification that will last about 30 days letting your callers know that the number has been disconnected and to call the number of your choice. If you'd like assistance, send me a private message with your full name, the primary phone number on your account and, your service address. I'll also need your Voice Security Pin so that I can make the change for you.
