Power: The Cisco 9951 Charcoal Slimline Handset is powered by the VoIP network and does not require a separate power source. This reduces the overall energy consumption and eliminates the need for a power outlet near the phone. The power consumption of the CP-9951-CL-K9 is low and contributes to the energy efficiency of the device.
Energy Efficiency: The CP-9951-CL-K9 is designed with energy efficiency in mind. The slimline design reduces the overall energy consumption and makes it an environmentally friendly choice. Additionally, the device features an automatic sleep mode that reduces energy consumption when not in use. The use of efficient power supplies and the low power consumption of the device further contribute to its energy efficiency.
The CP-9951-CL-K9 Cisco 9951 Charcoal Slimline Handset is equipped with various security and encryption features to ensure the protection of sensitive information during communication. These include:
- AES (Advanced Encryption Standard) Encryption - This encryption algorithm provides secure voice communication by encrypting the voice payloads in real-time, ensuring that the data transmitted between handsets is protected.
- Authentication - The handsets use digital certificates to authenticate themselves to the Cisco Unified Communications Manager. This helps prevent unauthorized access to the communication network.
- Transport Layer Security (TLS) - This protocol provides secure communication over the internet by encrypting all data transmitted between the handsets and the Cisco Unified Communications Manager.
- Secure Real-time Transport Protocol (SRTP) - SRTP provides end-to-end encryption of voice and video calls, ensuring that the data transmitted during a call is protected from eavesdropping.
- Secure Provisioning - The handsets can be securely provisioned and updated over the air (OTA) to minimize the risk of unauthorized access to the device and its firmware.
