3.4 Initial Boot-Up and Configuration

Once connected to power and network, the phone will automatically begin its boot-up sequence.

This may include firmware updates.

• The phone's display will show progress messages.
• Upon successful configuration, your extension and name should appear on the display.
• The phone supports SIP protocol. Ensure your call management system is configured accordingly.
• For remote site usage, the phone includes an SSL VPN client. This feature requires an ASA firewall at the remote end and a specific AnyConnect for Phone license. Consult your IT administrator for VPN setup.
