Nalee, who's the manu.?
Has it not occurred to you that Don has probably already perused the manual?
I should expect that someone who declares themeselves MCP, which I assume is a Microsoft Certified Professional, to have better customer service skills, and better manners in general.
Don, you may want to check with Suddenlink to be sure their digital phone service supports sending faxes. Most digital services do. Some don't.
You say you've set up the information. I'm assuming that you load the paper you want to fax, enter the number, and press Send. Nothing happens after that? Do you hear the fax dialing out? Most faxes will scan the pages before attempting to make the phone connection. Does the machine scan your pages?
Also, Don, as a gentle reminder, most all in one units "default" to Copy mode. I trust you are engaging the Fax mode?
