Your Extension’s Accessories

Operation in Headset Mode

Once the headset connection has been validated, you may then, 

at your leisure, operate your extension either in headset or handset

A new call is presented on your idle extension in the standard manner 

through an audible, single, discreet signal emitted over the headset, 

rather than your extension’s usual ring, which is automatically de-

activated.
However, according to the programming for your facility, this signal 

heard in the headset may be accompanied by a repetitive signal 

also heard on your extension’s loudspeaker. This signal is repeated 

every 5 seconds until you answer the call that is presented to you 

on your idle extension.
You will be notified of a new call presented on your extension with a 

single ring heard over your extension’s headset. This is also true for 

any call that is on hold.
