Types of Cisco IP Phones VoIP


Cisco IP Phones offer the high-quality, reliable communications your business needs every day. They also add new capabilities that increase your ability to collaborate within the workplace.

Thanks to network integration, these phones are easy to install, manage, and update. Our broad portfolio can help you improve productivity, foster collaboration, and reduce operating expenses.

With the proliferation of Voice over IP (VoIP) telephone technologies, Cisco phones have become a popular choice because of an extensive selection of models covering a wide range of needs. While they employ features specific to the Cisco VoIP servers, these phones can also be used with "open source" VoIP technologies. As the phones progress toward the 9900 series, more features become available. The models listed here range from basic cubicle phones to sophisticated phones that include video conferencing capabilities.

This entry-level phone offers a graphical display that can display basic images such as a corporate logo. The display also features scrollable menu selections to access additional features.
