• Make sure there aren’t any bandwidth hogs running. If there is a high-bandwidth application running, try pausing it and see if that clears up your phone call. High bandwidth applications include:
  • File sharing or other peer-to-peer applications like BitTorrent, Limewire, Kazaa
  • Graphic-heavy online games like World of Warcraft, League of Legends, or Call of Duty
  • Uploading large files with FTP programs
  • Sending email with big attachment sizes


• Turn off (or unplug) your modem and phone adapter, wait a couple minutes and turn them on again starting with the modem


• Keep your VoIP phone adapter (the special router you received from telnet when you signed up) well ventilated so it doesn’t overheat

• Make sure your VoIP phone adapter is positioned at least 3 feet away from any electronic device that might cause interference


• Reboot your adapter, modem and computer (It may seem silly but often works.)
  
  To reboot your phone adapter:
  1. Pick up a phone that is connected to the phone adapter
  2. Dial:* * * * (star 4 times) even if there isn’t a dial tone
  3. Dial REBOOT# (732668#) and hang up
  
  This will reboot the Phone Adapter


• If you have multiple routers or other networking equipment, try plugging your phone adapter directly into the Internet modem. If this solves the sound issue, you might have a problem with one of the other pieces of equipment. Gradually add the equipment back into your setup until you’ve identified the one that’s causing the problem

If none of these solutions solve the problem, contact technical support at 1-855-835-6381 or support@telnetcommunications.com.
