Features and Capabilities


The cost-effective Cisco IP Phone 7800 Series is ideal for small to large enterprises seeking high-quality, full-featured VoIP communications.

Customers who use traditional analog or digital phones and wish to advance to a Cisco IP Phone system, whether deployed on-premises, from the cloud, or in hybrid configurations with the Cisco Spark Phone OS are a great fit for the 7800 Series.

In addition, customers who would like to expand their existing Cisco voice communications desktop investment can take advantage of these endpoints.

The 7800 Series, with pre-loaded multiplatform phone software (i.e., firmware), can also be deployed by organizations who have made, or are considering, investment in UCaaS services from Cisco pre-approved third party providers.

Enhanced User Experience for Collaboration

Key features and capabilities that promote a superior user experience include:

  • Single, multi-line models for desktops and an endpoint for small conference rooms
  • Backlit, pixel-based displays with soft keys
  • Fixed keys for conferencing, messaging, directory and two-way navigation ease use
  • Wideband audio and full-duplex communications deliver crystal clear voice
  • Electronic hook-switch control to more easily manage personal calls on most models

Simple, Cost-Effective Administration

The IP Phone 7800 Series is easy to deploy and manage, with features such as:

  • Flexible deployment options for On-premises and cloud with Cisco Spark, along with Cisco pre-approved UCaaS providers
  • Low power consumption and Cisco EnergyWise to reduce energy costs
  • Integrated IEEE switches to reduce installation costs and clutter at the desktop
  • Cisco Expressway for remote worker single sign-on access without a VPN client
