2. Initial Boot-up and Configuration
Once connected, the phone will power on automatically and begin the boot-up process. This may take a few minutes.
- The phone will attempt to obtain network configuration (IP address, subnet mask, gateway, DNS) via DHCP.
- It will then attempt to register with your call control system (e.g., Cisco Unified Communications Manager or Cisco Webex Calling).
- Follow any on-screen prompts for initial setup, such as language selection or network settings if DHCP is not available.
Note: This device is optimized for Cisco Webex Calling. A Cisco Webex subscription must be purchased separately for full functionality.
