• [x] The phone numbers in Top Blocked/Top Permitted Callers should be links to Call History
• [x] The phone numbers in Blocked Numbers and Permitted Numbers should be links to Call History
• [x] A "Play" button is needed on the View Call page (even though there is a play button on the audio controls)
• [x] A" Back" button is needed on the Call History pages
• [x] A" Back" button is needed on the Blocked Numbers
• [x] A" Back" button is needed on the Permitted Numbers
• [x] Help buttons (question or info icons) are needed on each page
• [ ] ~The name search behavior is a little wonky - it clears and resets to a phone search after using it~ Maybe later.
