Problem Cause/Solution
I cannot make a call. •Check if the STATUS indicator or indicator is lit in
green. If it is not lit in green, refer to the User Guide on the
Panasonic Web site (® see Introduction).
•You cannot make a call while the base unit is downloading
the firmware update. Wait until the STATUS indicator or
indicator stops flashing and changes to steady green.
•The handset is too far from the base unit. Move closer and
try again.
•Check the VoIP status in the Web user interface and
confirm that each line is registered properly (® see To
check the setting status in the Web user interface in
this section).
•Check that the SIP server address, URLs of the
configuration files, encryption key, and other required
settings are correct.
•Check the firewall and port forwarding settings on the
router (® see 1.1.10 Other Network Settings).
•Check [Multi Number Settings] in the [Telephone] tab in
the Web user interface (® see 3.7.1 Multi Number
Settings).
•If 3 calls are being handled by the base unit and/or
handsets simultaneously, a new call cannot be made from
the unit.
•For details about settings, consult your network
administrator or phone system dealer.
Password for Web User Interface Programming
Problem Cause/Solution
I have lost the login password of the Web
user interface for the Administrator or User
account.
•Reset the password from the base unit or one of the
handsets. The passwords for both Administrator and User
will be reset (® see 2.1.6 Reset Web ID/Password).
For security reasons, it is recommended that the
passwords are set again immediately (® see
3.5.2 Administrator Password or 3.5.3 Change User
Password).
