Cleaning Your Telephone
Suggested Solutions
Verify that the power cord is fully inserted in the
correct connector on the underside of the
telephone. Use the strain relief tab to prevent the
cord from becoming unplugged.
Verify that each Ethernet cable is connected and
that each cable is in the proper connection.
Remove and add power to the telephone by
unplugging the power cord at the electric outlet
and plugging it back in.
If the telephone is powered through a powered
Ethernet cable, make sure that power is applied to
the cable at its source.
Your telephone has lost the connection to the
system. Remove the Ethernet cord from the jack,
and then re-insert it into the jack.
Wait a few seconds. If the telephone still appears to
be locked, disconnect the electrical power for your
telephone, and then plug it back in.
Your mailbox may be full. Log in to your voice
mailbox and delete some messages.
Your telephone may be set up for Greeting Only
Mailbox. Log in to NBX NetSet > NBX
Messaging and clear the Greeting Only Mailbox
checkbox.
