If your Alcatel-Lucent IP Phone's PC Sync displays 'Unable to listen to the port', ensure that no other applications are currently using the same port. Additionally, verify that your firewall settings are configured to allow listening to this port. If the issue persists, try changing the port used by PC Sync.
