Cisco – IP 7940G

The Cisco IP Phone 7940G is a legacy enterprise-grade VoIP phone designed to provide high-quality, secure voice communication for office users and knowledge workers. With support for two active lines, the 7940G delivers a balance of usability, functionality, and durability, making it a widely adopted IP phone in Cisco Unified Communications deployments.

Equipped with a large, 320×222-pixel grayscale LCD display, the phone provides easy access to call information, directories, and configuration settings. It features programmable line and feature keys, a built-in speakerphone, headset support, and context-sensitive soft keys, offering a flexible interface for handling calls efficiently.

Key features include:

• Two SIP or SCCP-enabled lines for call flexibility

• High-quality audio with wideband support (via firmware upgrades)

• Built-in full-duplex speakerphone and headset port

• Large LCD display for caller ID, call status, and settings

• Power via IEEE 802.3af PoE or optional external power adapter

• Integration with Cisco CallManager (CUCM) and Cisco CME

• Customizable ringtones and user settings for personalization

Although now end-of-life (EOL) and replaced by more modern models like the Cisco 8800 and 7800 series, the 7940G remains in use in many legacy networks due to its proven reliability and ease of deployment in Cisco VoIP environments.
