Line/Call Appearance Keys
The 55i has 4 hard line/call appearance keys each with a corresponding
status light. Additional line/call appearances may also be set up on your
phone as softkeys.
These line/call appearance buttons and lights represent physical lines or
calls for your extension. By pressing a line/call appearance button, you
connect to the line or a call it represents. The line/call appearance light
indicates the status of that line or call.
When the phone is taken off-hook, the phone will automatically select a
line for you.
For more information about the Line/Call Appearance keys, see the
Aastra Model 55i IP Phone User Guide.
Using a Headset with your Telephone
The 55i accepts headsets through the modular jack on the back of the
phone. Contact your telephone equipment retailer or distributor to
purchase a compatible headset. A non-amplified headset is required.
Customers should read and observe all safety recommendations
contained in headset operating guides when using any headset.
Note: For best headset performance, Aastra recommends non-amplified headset
equipped with modular connector.
