Press and hold the DSS key for 10 seconds until you hear a beep, then press it once quickly and the device will announce its IP address.
For indoor monitor devices:
Non-touchscreen models: Bi51W, Bi52W
Press and hold the OK key, then go to System Information —— Network —— IPv4.
Touchscreen models: Bi53W, Bi56A
Go to Menu —— Status —— Network —— IPv4.

Settings for the Bi6X Series and Bi51X Indoor Monitor Series
1. Log in to the web interface, then go to Function Key —— Function Key Settings.
① Type: Memory Key
② Value 1 and Value 2: enter either the phone IP address or the SIP account registered on the server

Important Notes
When using IP direct calling, you must disable the device restriction for IP direct dial. Using the i53W as an example, go to Line -> SIP -> SIP Global Settings, then clear the Enable Strict UA Match option, as shown below, and click Submit to save the setting.

You also need to go to Line -> SIP -> Basic Settings, then enable Allow Unregistered Outgoing Calls and click Submit to save the setting.
