"KNCTR fans,

We are getting lots of great feedback and are currently working on some upgrades to the system to improve the KNCTR app for everyone. As such, you may experience some temporary interruptions when making calls with the KNCTR phone. Thanks for your patience. We continue to look for ways to provide the best possible experience for you!
Sincerely,

The KNCTR Team"
