The WHCA is a joint military unit that provides the president with secure and non-secure communications in Washington as well as during presidential travels. This telephone replaced an old Cisco 7975 IP phone in September 2017 and connects to the so-called Signal switchboard of the White House Communications Agency (WHCA).

The standard, unmodified Cisco 8851 IP phone on Trump's desk was for the highly secure Executive Voice over Secure IP-network which is part of the Crisis Management System (CMS) and connects the President, the National Security Council, Cabinet members, the Joint Chiefs of Staff, various intelligence agency headquarters and watch centers, as well as Continuity of Operations (COOP) sites.

This telephone connects to the regular White House switchboard in the basement of the Eisenhower Executive Office Building, where operators can set up calls to whoever the president wants to speak with. The modified Cisco 8851 IP phone was placed on the president's desk by the end of 2016, replacing an old Avaya/Lucent 8520T of the internal White House telephone network which is used for all kinds of unclassified phone calls.
