Objective

The attendant console helps to increase the extension numbers of the SPA500 series IP phones. With the help of an overlay button you can easily map up to 25 lines in one single button which overcomes the use of limited buttons on an IP phone. To configure an overlay extension at least two normal, shared, or central office line extensions are needed.

This article explains how to configure an Overlay extension on SPA500S through the use of SPA500 Series IP Phones which is connected to a UC500 series device.

Note: To configure an overlay button on an SPA500S Attendant Console which is connected to SPA500 series IP phone, first you need to configure Extension Mobility User Profile for dual line. Because octal lines do not support overlay buttons. To know more about how to configure Extension Mobility User Profile refer to Configuration of Extension Mobility Feature on UC500 Series. The SPA500DS will not work with the UC500 series unified communication devices and will only work with UC320 unified communication device.
