(1) CP-HANDSET-CORD
*Power Adapter not included
Keeping your workforce connected with clear, reliable voice communications shouldn't mean compromising on features or network efficiency. The Cisco Unified IP Phone 7945G (CP-7945G) delivers enterprise-grade VoIP telephony with wideband audio, a vibrant 5-inch backlit color display, and integrated Gigabit Ethernet — all in a proven, widely deployed form factor from the Cisco 7900 Series.
Designed for transaction-type workers and professionals with significant phone traffic, the CP-7945G provides direct access to two telephone lines, four context-sensitive soft keys, and an intuitive four-way navigation cluster. The large 320×240 color TFT display makes it easy to view caller information, access directories, and run XML-based applications. High-fidelity G.722 wideband audio is supported across the handset, speakerphone, and dedicated headset port, ensuring lifelike voice quality in every conversation.
The built-in 2-port 10/100/1000 Ethernet switch lets you share a single network drop between the phone and a PC, with 802.1Q VLAN separation for voice and data traffic. Power-over-Ethernet (IEEE 802.3af) support simplifies deployment by eliminating the need for a separate power adapter at each desk. Whether you're expanding an existing Cisco Unified Communications environment or sourcing cost-effective replacements, the CP-7945G remains a dependable, feature-rich IP phone.
Features & Benefits
High-Fidelity Wideband Audio
The CP-7945G supports G.722 wideband audio across the handset, speakerphone, and headset port, delivering vibrant, lifelike voice quality. Full-duplex speakerphone with acoustic echo cancellation ensures clear hands-free conversations. Internet Low Bitrate Codec (iLBC) support also provides resilient audio quality on lossy networks.
Vivid 5-Inch Color Display
A 5-inch TFT active-matrix color display with 320×240 resolution and 16-bit color depth provides easy-to-read caller information, call logs, and application interfaces. The backlit screen supports double-byte Unicode encoding for localization in over 30 languages, making it suitable for global deployments.
Integrated Gigabit Ethernet Switching
The internal 2-port 10/100/1000BASE-T Ethernet switch allows a direct connection to the LAN and a pass-through connection for a colocated PC — all through a single network drop. Administrators can designate separate 802.1Q VLANs for voice and data, improving security and traffic reliability.
Flexible Protocol & Platform Support
Supporting both SCCP and SIP protocols, the 7945G integrates seamlessly with Cisco Unified Communications Manager and Cisco Unified Communications Manager Express. Firmware updates can be downloaded from Cisco.com, and the phone's dynamic feature set keeps pace with evolving requirements without hardware changes.
Enterprise Security Features
The CP-7945G supports X.509v3 certificates for positive device identity, digitally signed firmware images, and secure signaling and media with AES-128 encryption. An 802.1X supplicant with EAPOL pass-through provides network access control at the port level.
Deployment Scenarios
Enterprise Office & Transaction Workers
Ideal for employees with significant daily phone traffic — receptionists, customer service agents, and administrative staff. The two-line support, color display, and wideband audio provide a productive, comfortable calling experience throughout the workday.
Bandwidth-Intensive PC Colocated Desks
The integrated Gigabit Ethernet switch with 802.1Q VLAN support lets knowledge workers share a single network drop between their phone and PC without sacrificing bandwidth or security. This reduces cabling costs and simplifies desk provisioning.
Cost-Effective Fleet Expansion or Replacement
Organizations running Cisco Unified Communications Manager can deploy pre-owned CP-7945G units to expand or refresh their phone fleet at a fraction of the cost of new endpoints, while maintaining full feature compatibility with their existing infrastructure.
