Troubleshooting tip

I am not able to block or unblock a number
  • You may have encountered the issue when Sorenson's servers are temporarily unavailable. Try these troubleshooting steps in the order to resolve the issue, stop when the issue is resolved:
    1. Force quit app then login again or reboot the VP.
    2. If using ntouch mobile or VP on the home network, reboot modem and router.
      • Try plugging ethernet into different network port.
      • If using router, try bypass the router and connect directly to the modem.
    3. Check your internet to make sure it is working as expected. Open a web browser and if it opens Internet Service Provider page containing some kind of warning then there may be issue with your provider and you may need to call them.
