Auto Detection of Key Expansion Modules

You can configure a new phone to auto-detect the maximum number of key expansion modules that it supports.

For these phones, the Number of Units field shows the maximum number of key expansion modules that the

phone supports as the default value. When a user adds key expansion modules to these phones, the module

lights up and is enabled automatically. Default value of this field is 2 for Cisco IP Phone 8851 and 3 for Cisco

IP Phone 8861. Navigate to Admin Login > Advanced > Voice > Att Console to check the value of the

Number of Units field.

If your user has an older release phone and it is upgraded to the current release, you can change the cofiguration

of the phone so that when the user adds a key expansion module to the phone, it lights up and is enabled

automatically.

Make sure that the screws are fully inserted into the phone and tightened.
