Hi Lily2, first, verify that Simultaneous Ring is activated in Voice Tools. Log into your Cox.com account with your Primary Username, and then go to
http://phonetools.cox.com. Click "Settings" to expand the options. If active, the button next to Simultaneous Ring will appear blue. If not yet active, the button will be gray. Once active, space is provided so you can add up to 3 phone numbers. Make sure your Nomorobo number (provided by Nomorobo when you create an account) is entered here, and then click Save. After you've completed those steps, go back to your Nomorobo Account (
www.nomorobo.com/phone). Go to "Your Phones" and click "Test" next to your number. Then click "I'm ready. Call Me Now." You should immediately receive a call letting you know if everything is set up correctly. Wait until the third ring before answering the call. Do you receive the test call from Nomorobo successfully? -Becky, Cox Support Forums Moderator
