Why I cannot make a call with my Panasonic KX-UT670?
- JJohn MurphyAug 28, 2025
If you cannot make a call on your Panasonic Telephone, check the VoIP status in the unit's notification screen and confirm that each line is registered properly. Also, verify that the SIP server address, URLs of the configuration files, and encryption key are correct. Make sure to check the firewall and port forwarding settings on the router. For further assistance with these settings, it is recommended to consult your network administrator or phone system dealer.
