Possible Solution(s)
The Network Disconnected prompt appears on the display
and the telephone status lamp turns on if phone is not properly
connected to the network. The phone also displays the default
time and date of 12:00 am Jan 1st, 2005 or the equivalent.
Check that the cables are tightly connected to the phone and to
the wall jack. The phone should automatically detect when it is
reconnected and will display the "Network Connected" prompt
for a few seconds.
However, if changes have been made to your phone's network
settings, you may need to restart your phone.
Contact your system or network administrator for assistance.
Ensure that power is being provided to your phone. If your
network does not provide inline power over Ethernet, you can
obtain an additional accessory, the Aastra PoE (Power over
Ethernet) inline power supply, to provide power over Ethernet
locally to your phone.
See the section "Connecting to the Network and to Power" in
the Aastra Model 6757i Installation Guide for details.
If you press the Speaker key and the speaker lamp flashes
and you do not hear dial tone through the speaker, the
option in the phone's Options list has been set up for headset
use.
Press the Speaker key a second time and if the lamp goes out,
the phone has been set up to be used only with a headset or
handset. If the lamp stays on steady and you hear dial tone, the
phone has been set up so that you can alternate between the
speaker and the headset by pressing the Speaker key.
Check for any loose connections and that the phone has been
installed properly. For installation instructions, refer to the
"Installation and Setup" section in the Aastra Model 6757i
Installation Guide provided with your phone.
Check the ring volume on your phone. It may be turned down
or turned off. To adjust the ringer volume setting, press the
volume key when the phone is on-hook and idle.
Your phone system or service provider must provide a Visual
Message Waiting service for this function to work. Contact your
system administrator.
Check to ensure that the handset cord is fully connected to
both the phone and handset. The handset connection on the
bottom of the phone is marked with the handset symbol
This setting is in the Options list. See Status.
