Cisco CP-8831-K9 IP Phone Overview

 

Take full control of conference calls with this Cisco Unified IP conference phone. It delivers superior high-definition audio and 360-degree coverage for conference rooms in a variety of sizes, along with executive offices. This phone system is a technologically advanced solution for highly secure communications, boasting wideband, full-duplex audio performance. The Cisco Unified IP conference phone delivers highly secure, comprehensive, mission-critical unified communications with especially comprehensive audio performance and flexible accessory options. Security is ensured thanks to device authentication and signaling encryption, which uses Transport Layer Security (TLS) with Advanced Encryption Standard 128 (AES-128). This Cisco phone system also includes support for daisy chaining two units, providing extended room coverage. Because it has a two-element speaker, the phone can capture the full voice spectrum, ensuring clear acoustics throughout the audio communication. Support for DECT wireless extension microphones is another feature of this conference call system; up to two microphones can be used simultaneously. This device also features Session Initiation Protocol (SIP) signaling, allowing for Internet telephony function for voice and video calls over online connections.
