What should I do if I hear little clicking sounds when dialing out?

This is most likely a symptom of your Flashback being in "DP mode."

To troubleshoot, please try toggling the small button at the bottom right of your Flashback's keypad from DP mode and then back to TT mode to see if that does the trick!
 

If not, please send us a note at support@tincan.com and we'll be happy to help with more troubleshooting?
