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 RJ45 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 RJ45 cable, make
■
sure that power is applied to the cable at its source.
Your telephone has lost the connection to the system. Remove the
■
RJ45 cable 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
