Greetings, glennturner! I appreciate you taking the time to reach out to us here on the forums. I hope you are having an amazing day. I would like to assist you with this. Can you verify if you're trying to unblock your number when you make a call or is it a call coming into you?
If it's for a call coming to you, you should be able to find some helpful information here: https://www.xfinity.com/support/articles/call-screening
If it's for your number when you make a call you should be able to find that information here: https://www.xfinity.com/support/articles/caller-id-blocking-by-line
