IST-2
Integrated Services Telephone - wanted item

IST-2 is an integrated services desktop telephone for secure/non-secure conversations, in­tro­duced around 2003 by Raytheon in St. Petersburg (Florida, USA) and subsequently manu­factu­rerd by Telecore, Inc. in Richardson (Texas, USA). It is intended for use on the US Defense Red Switch Network (DRSN) [1] and is therefore also known as a red phone. The IST-2 itself does not feature encryption/de­cryption, but instead relies on the bulk encryption features of the local PABX.

The device has 50 software-defined but­tons – in a 5 × 10 layout – for direct access to a central office line (CO) or a local subscriber. To the left of this direct access field is a numeric dial pad with the regu­lar 12 buttons, plus an extra row of red buttons for precedence and priority override, similar to the red buttons on the telephone sets of the old AUTOVON/AUTOSEVOCOM networks.

The difference with the old AUTOSEVOCOM network – which faced many problems and high cost – is that communication over the twisted pair line is digital rather than analogue (POTS).
  

The IST-2 is only suitable for connection to a DRSN switch, which allows its users to place secure as well as non-secure calls directly, without installing encryption keys and/or using a Crypto Ignition Key (CIK). In a DRSN network, security is handled by the local switch, rather than by the individual terminals, which makes setting up a call or a conference much easier for the users.

The IST-2 was introduced around 2003 and replaces the its predecessor – the Raytheon IST – and the older MLP-1A made by Electrospace Systems, that had been in use since 1983. The IST-2 was phased-out around April 2011 during the presidency of Barack Obama. It was replaced by two separate phones: an Avaya/Lucent 8520T for non-secure calls through the regular White House switch, and a Cisco 7975G Unified IP Phone () for secure calls [4].

Presidential communications
US President George W. Bush
The image on the right shows US President George W. Bush (2001-2009) using the IST-2 on his desk in the Oval Room at the White House for a conversation with British Prime Minister Gordon Brown on 7 October 2008.

Although the 50 speed-dial buttons of the IST-2 were usually covered by a grey panel when the press was in the room, it ocassionally slipped the attention of the White House staff, revealing the direct contacts of George Bush [2].

US President Barack Obama

The IST-2 on the President's desk was replaced in March or early-April 2011, by two modern phones: an Avaya/Lucent 8520T for non-secure calls, and a Cisco 7975G Unified IP Phone with expansion module 7916 for secure calls through the Executive Voice over Secure IP network [4].
