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).
