Things to do when you first get your One Net Business mobile phone

When you first get your mobile phone

  1. Ask your administrator to add your mobile phone to One Net Business.
  2. Download the Webex app and install it on your mobile phone.

Your two phone numbers

When you use a mobile phone with One Net Business, you get two numbers, your One Net Business number and your mobile number. Your One Net Business number looks like a fixed line number, but you can make and receive calls with it from any device.

Your One Net Business number is your default number, but in One Net Manager you can switch between using your One Net Business number and using your mobile number as the outgoing caller ID from your mobile.

Using your mobile phone

Making calls and sending texts with your One Net Business phone

By default, you make and receive calls with your One Net number, but you send and receive text messages with your mobile number.

You can either use the Webex app to exchange messages using your One Net number, or send standard text messages with your mobile number. If someone sends a standard text message to your One Net number, it won't be delivered.

Using feature access codes on your mobile phone

You can use feature access codes (FACs) on your mobile phone just like you do on your other devices. FACs allow you to:

  • Perform call services from your phone, such as picking up a call and pulling a call from one phone to another
  • Activate or deactivate call services, such as do not disturb and call forwarding
  • Check whether some services are currently active

Using extensions on your mobile phone

When you dial some extensions on a mobile phone, you are redirected to other phone numbers. For example, when you dial an extension that begins with an emergency number, you are connected with that emergency number.

The following groups of extensions cause redirects to other phone numbers:

To prevent calls to those extensions from being redirected

  • Dial <location dialling code of the user's site> <the user's extension>, for example, 66 1120.
