Set Audio
The 53i allows you to use a handset, a headset, or handsfree to handle
incoming and outgoing calls. The audio mode option provides different
combinations of these three methods to provide maximum flexibility in
handling calls. There are four audio mode options to choose from:

Headset Mic Volume

To adjust the headset microphone volume, press Advanced after selecting
the audio option, and then select the Low, Medium, or High volume level.

This is a system administrator level-only option, and requires a password
to access. See the AastraLink RP Administrator Guide for details.
Phone Status
This option allows you to:
• View your network status including your phone’s IP and MAC address
• View your firmware version
• Restart your phone
There is also a system administrator level-only option to reset the phone to
factory default settings. See your system administrator for details.
