If you are unable to make a call from your MiiTel Phone, the following may be the cause. Please check each solution.

The other party is on a call


If the other party is answering another call, you will hear a long electronic tone that sounds like "poo poo poo". In this case, please allow some time to call back.

You are calling a non-existent phone number


In rare cases, when you call a non-existent phone number, the voice guidance such as "The number you have dialed cannot be connected" may not play. Please make sure that you are calling the correct number.

You are calling a phone number that cannot be dialed

  • MiiTel supports toll-free numbers (starting with 0120, 0800), navi-dial numbers (starting with 0570), and emergency calls (110, 119, etc.). code>119, etc.) are not supported.
  • .
  • International calls to some countries are not supported. For details, please see "Making international calls".

Your network is going through a proxy


If your organization's network uses proxies (including products called L7 firewalls and web filtering), these products may be blocking voice communications. For more information, see "Confirmation of use".

Failed to load


In rare cases, the connection may fail due to incomplete loading of the MiiTel application. In this case, a forced reload (Ctrl + F5 key on Windows, Command + Shift + R key on macOS) in some cases.

No outgoing phone number is set in your account


If you receive an announcement that says "You cannot make a call because the phone number you want to use is not registered" when you make a call, it is likely that you do not have an outgoing phone number set up for your account. Please make sure that your phone number is set. For more information, please see "Setting up an outgoing phone number for users".
