Flash Detection Time (131)
The Flash signal generated by a Standard MF telephone will only be detected if it is within the range configured for the system.
It is therefore recommended that you check the Flash detection time of MF telephones and adjust the settings to approximate
them as much as possible.
The configurations for detection of Flash may vary from country to country.
The system has the capability for Automatic Flash Detection.
Overflow/Escape Extension (132)
An overflow extension only receives calls when the extension that was called is not available, does not answer or was not
programmed.
The overflow extension can be accessed through the specified internal number and
cannot be used or programmed as a Fax extension.
Hotline (145)
This function lets you dial a number previously programmed into the Phonebook automatically as soon as the handset is lifted.
Multiple extensions can dial a number programmed in the Phonebook.
Warmline (162)
It allows you to specify a period of time for activating the Hotline.
Each extension can have a different timeout set for the Warmline, from 0 to 9 seconds.

This feature allows you to assign many extensions to one executive telephone.
There are 8 groups available with 16 extensions each (all extensions must use system telephones).
