When placing test calls, try these ideas:
  • Make sure the number you dialed is correct, then try the call again. For example, you might need to dial 9 for an outside line or include a long distance access or country code.

  • To find out if the problem exists in your system, ask the person you were trying to reach to call you instead.

  • Find out if the system you are calling is powered on and is functioning properly.

  • If you can make calls but not receive them, make sure that your system is configured with the correct number.
