On January 20, 2021 the 46th president of the United States was inaugurated into office. As such he had access to the presidential communications system, including secure and non-secure telephone lines.

There was small and unnoticed changes in the telephones on the desk of the new president, as well as what happened to the call device that became known as Trump's "Diet Coke Button".

The telephones on the President’s desk

On the first day as president, the Oval Office of the White House By then, this famous room had already been redecorated with new paintings, busts and photographs, while Trump's beige rug had been replaced by the deep blue one from Bill Clinton's Oval Office. The flags of the five branches of the US Armed Forces have also been removed.

A close look at the photos shows that there was also a small change in the telephone equipment. On Biden's presidential desk there are now two identical phone sets, which can be identified as the high-end Cisco IP 8851 Phone:

Both phones are not the standard commercially available model, however, as they have been modified by a small communications security company called Advanced Programs, Inc. (API). This can be recognized by the dark gray metal box at the back side of the phone's color display and an additional red button on the front panel of the phone:

The purpose of these modifications is to provide on-hook security for the handset and the speakerphone and probably also for TEMPEST protection - to make sure that the phone cannot, either accidentally or deliberately, pick up and transmit audio when the handset is on-hook.

Comparing the two phones on Biden's desk with the ones used by President Trump, we see that under Trump only one of the Cisco 8851 IP phones had the aforementioned modifications. The other phone was the standard model:

Unclassified phone calls

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.

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.

Classified phone calls

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 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 WHCA is a joint military unit that provides the president with secure and non-secure communications in Washington as well as during presidential travels. The Signal board also connects to the White House Situation Room.

Despite being used for classified conversations, the Cisco 8851 IP phone for secure calls wasn't equipped with the additional security features like the non-secure telephone - probably because secure calls travel over a separate, encrypted network, which mitigates the risk that adversaries can abuse the phone's microphones for eavesdropping.

But now, under president Biden, the phone for secure calls also has the modifications for on-hook security. Maybe this was considered safer, or maybe it's just to make both phone sets look the same, so outsiders cannot see whether the president is making a classified or an unclassified phone call based upon which telephone he is using.

Usually, the phones for the secure top-level telephone network can be recognized by a bright yellow faceplate, as can be seen at the modified Cisco IP phone that is used when the president is outside the White House, for example.

Yellow is the color code for the highest classification category: Top Secret/SCI, but in the Oval Office this would probably stand out too much, so here this phone just has the presidential seal in the bottom left corner of the black display section:

Update #1:

Around the first of February 2021, there was another small change in the phone on Biden's desk in the Oval Office: as can be seen in the picture below, the Cisco IP phone on the left, probably the one for unclassified conversations, now has an Key Expansion Module attached to it, which provides 14 additional programmable direct line buttons.

Under Obama, the old Cisco 7975 IP Phone for secure calls had a similar expansion module, but under President Trump that module was removed. Apparently he saw no need for having the extra direct line buttons, probably because he could always make calls via the White House switchboard operator, but it also symbolized that there was only a very small group of people he was in contact with.

Update #2:

On February 18, 2021, the White House released a photo in which we see president Biden in the office of his secretary, just outside the Oval Office. On the desk in front of him are the same modified Cisco 8851 IP phone sets as on his own desk, although here, both have an additional Key Expansion Module.

In the Oval Office, the phones have brown network cables to blend in with the furniture, but in the secretary's office the cables are color-coded: green for the Unclassified network and yellow for the Top Secret/SCI telephone network:

The president's call button

While the small change in phones wasn't noticed, there was quite some media attention for something that appeared missing on the desk of president Biden: the wooden box with the presidential seal and a red push-button, which became known as Trump's "Diet Coke Button".

The removal of this box was just temporarily though, because meanwhile it has been placed back on the president's desk, as can be seen in this photo from January 25:

Trump's "Diet Coke Button"

There are a lot of stories about how President Trump used the button. Former White House communications aide Cliff Sims, for example, wrote in his 2019 book Team of Vipers that Trump would prank visitors by hitting the button and suggesting it was related to the country’s nuclear weapons arsenal.

"Out of nowhere, he'd suddenly press the button," Sims wrote. "Not sure what to do, guests would look at one another with raised eyebrows" he added. "Moments later, a steward would enter the room carrying a glass filled with Diet Coke on a silver platter, and Trump would burst out laughing."

On Twitter, Times Radio political commentator Newton Dunn recalled a similar situation: "When Tim Shipman and I interviewed Donald Trump in 2019, we became fascinated by what the little red button did. Eventually Trump pressed it, and a butler swiftly brought in a Diet Coke on a silver platter."

Earlier usage of the call button

The fancy walnut box used by the President to call his Valet for services goes back to the Nixon Administration. WHCA technicians were pretty crafty at fabricating things after going to Radio Shack and purchasing a bag of components. The original "Valet Call System" was locally fabricated by purchasing the mechanism for a "Sears Garage Door Opener" and then remounting the electronics inside a wooden housing. That proved to be the quick and easy way, they actually had to buy a complete garage door opener, motor, chain, mounting rails, and the works, only to keep the guts for the call box. Push the button, and it would trigger a relay in the nearby kitchen or other nearby room for the Valet's to respond. I am sure they have advanced to a off the shelf product after 50+ years. Both the Western White House in San Clemente and Key Biscayne as well as Camp David had WHCA fabricated Call systems.

The box with the call button is in the Oval Office  not only on the president's desk, but also on a side table in the seating area and in the small presidential dining room nearby the Oval Office.

The button has nothing to do with nuclear command and control, but can be used by the president to summon assistance. According to earlier sources, it was meant to alert the Secret Service, while others say that pushing the button makes an aide come in for whatever the president may need.
