caller ID shows as unknown on outgoing calls

@user_933f1c, I understand how frustrating it is when your outgoing calls show as "Unknown" instead of your phone number. This can happen for several reasons, including caller ID settings on the device, account-level caller ID configuration, or network-related issues. I'd be happy to help investigate further.  Here are the detailed steps to direct message us:
How to Send Us a Direct Message:
1. Click "Sign In" if necessary.
2. Click the "Direct Messaging" icon.
3. Click the "Start new conversation" (pencil and paper) icon. 
4. In the "To:" line, type "Comcast Business".
5. As you type, a drop-down list will appear. Select "Comcast Business" from that list.
6. An "Xfinity Support" graphic will replace the "To:" line.
7. Type your message in the text area near the bottom of the window.
8. Press Enter to send it.
