How do I stop telemarketers from calling?

You can use the Call Blocking feature through the Member Portal. However, the best way to stop receiving telemarketing calls on your TeleBlend phone is to register your TeleBlend number on the National Do Not Call Registry at www.donotcall.gov. To block a call, click the User Desktop link on the left when you log into the portal which will make a tab called Single appear on the top right next to the Logout link. Click the Single link and you will see your extension in the main window. Click the Address Book and then Add Number. Enter the First name as BLOCK and the number in the format 13015551212. Select Block in the drop down below it and then click Submit.
