Full Commercial Overview

The Cisco CP-7961G is an enhanced six-line executive-class IP phone in the Cisco Unified IP Phone 7900 Series, serving as the upgraded successor to the original CP-7960G. It is purpose-built for executives, department supervisors and administrative assistants who manage high-volume multi-line calls, shared extensions and colleague presence monitoring via BLF keysCisco.

This device supports dual native VoIP signaling protocols for flexible enterprise deployments: proprietary SCCP (Skinny Client Control Protocol) optimized for Cisco Unified Communications Manager (CUCM), and open standard SIP v2 for Cisco Unified SRST disaster recovery gateways and third-party SIP PBX systems. Unlike the triple-protocol CP-7960G, MGCP is not supported on the CP-7961G.

Core Hardware & Feature Differentiators vs Other 7900 Series Models

1. Backlit high-resolution 4-bit grayscale LCD screen: Major upgrade over the non-backlit monochrome display of CP-7960G, delivering crisp rendering of XML enterprise applications, multi-language Unicode characters and real-time call status dataCisco.
2. Six backlit tricolor programmable BLF line keys: Each key provides real-time visual presence monitoring for six independent directory numbers (DNs), a scalable multi-line feature unavailable on two-line CP-7941G/7942G and single-line entry models (7911G/7912G).
3. CP-7914 expansion module compatibility: Supports attachment of one or two 14-button CP-7914 expansion modules to add additional programmable speed dial and shared line monitoring keys for receptionist workflows.
4. Dual integrated 10/100 Fast Ethernet switch ports: Separate LAN uplink and PC passthrough port to daisy-chain office workstations without extra wall network jacks, optimizing cubicle cabling infrastructure.
5. Built-in dedicated RJ9 headset jack: Native wired headset operation without external adapter hardware, a feature omitted from low-tier single-line 7906G/7912G phones.
6. Dual PoE power support: Fully interoperable with both legacy Cisco pre-standard inline power and official IEEE 802.3af Class 2 PoE switches, compatible with mixed-generation corporate network hardware.
7. Factory pre-installed X.509v3 digital security certificates: Enables native device authentication against CUCM servers, streamlining enterprise network security compliance compared to the CP-7960G without preloaded certificates.

The chassis is constructed from scratch-resistant textured dark gray recyclable polycarbonate ABS plastic with a silver decorative front bezel. It ships with a fully adjustable foldable desktop foot stand supporting multiple viewing angles for ergonomic LCD readability; the foot stand can be fully detached for vertical wall mounting via keyed rear chassis cutouts, no mandatory wall-mount bracket included.

The CP-7961G reached official End-of-Sale (EoS) status many years ago; only limited critical security vulnerability and bug-fix maintenance support remains active, with no new feature firmware releases planned. Remote bulk provisioning, unattended mass firmware upgrades and centralized device monitoring are fully supported via TFTP auto-provisioning servers and embedded HTTPS web administration portal, fully compatible with Cisco CallManager 4.1 and later CUCM/CUCM Express releases, as well as Cisco Unified SRST fallback voice gateways.
