Problem
Network Disconnected
message
Why is my display blank?
Why is my speaker not
working?
Why can't I get dial tone?
Aastra - 2758-002
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 9133i SIP IP Phone 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
Audio Mode
option in the 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 9133i SIP
IP Phone Installation Guide provided with your phone.
