How to install AudioCodes 445HD IP Phone

• Unbox the phone, verify all components, and place the device on a clean, stable desk or choose a wall-mount setup if required.
• Connect a network cable to the LAN/Network port. If your network supports PoE, you can power the 445HD directly through the Ethernet switch to simplify deployment; otherwise, connect the included power adapter to the Power port.
• Connect the second Ethernet port to your computer or another network device if you need a pass-through connection for convenient access to the local network.
• Power on and allow the phone to boot. If your organization uses a centralized provisioning system, enable zero-touch provisioning or manually configure the SIP account settings as directed by your IT team or service provider.
• Enter your SIP credentials, server address, and any required security settings (TLS/SRTP, certificate validation) as provided by your PBX or cloud provider. Save the configuration and reboot if prompted.
• Test call functionality by placing a test call, adjust the display and sound settings for comfort, and set up speed dials or contact shortcuts for faster access. Document the setup for future reference and users’ guidance.
