October 2015 - On the audio side of things is a headphone jack (plus the side one via the detachable cooler mentioned earlier), DTS Headphone:X with 7.1 virtual surround sound and Hi-Res Audio support. The highlight, though, is the front facing stereo speakers that come with a ‘smart amplifier’. After our hands-on time, they’re easily some of the most powerful we’ve heard on a phone.
from the Galaxy S9+ and, well we have collected a lot of data from the field directly and from many other blogs so very complete his discussion here about October 2015, on this blog we also have to provide the latest automotive information from all the brands associated with the automobile. ok please continue reading:

The location that best represents Top Level Telecommunications in every sense of the word is probably
Air Force One, the aircraft that carries the president of the United States.
As unbelievable as it sounds, the telephone sets used aboard this plane dated back to the 1980s and so they were finally replaced by new ones in August 2012. Here we will take a look at this new telephone equipment, which is now used by president Obama when he travels by air.
The new phonesIn a range of pictures showing president Barack Obama using a telephone aboard Air Force One, we can see that the new phones consist of a handset in a customized cradle. In the conference room they have a rubber foot so they can be placed on the table without sliding away:

The phone sets to be used by the president in his office room and the conference room have a brown/goldish color that matches the wood and the leather chairs. All other handsets that have been installed throughout the plane are in standard gray:

In the back we see two new phones in gray on a wall mounted cradle.

These new phones aboard Air Force One can be recognized as the Airborne Executive Phone (AEP) made by
L-3 Communications. This is a military contractor that, among many other things, also manufactures the
STE, the secure desktop telephone that is most widely used by US military and government.
The Airborne Executive Phone is able to make both secure and non-secure calls from a single handset. It also provides
Multiple Independent Levels of Security (MILS) for digital voice and internet data access. This should provide end users with the experience of "reliable connectivity, interoperability and security they would have in an executive office environment".
Global Secure Information Management SystemsThe Airborne Executive Phone is part of L-3 Communication's Global Secure Information Management Systems (GSIMS). This is an IP-based system for secure airborne communications and has a modular, scalable, and redundant design.
GSIMS integrates existing analog and digital radio and interphone systems with its own IP-based architecture, this in order to provide reliable connectivity, secure video conferencing and controlled wireless connections. The system is effectively controlled from an operator workstation.

More details about the Global Secure Information Management Systems (GSIMS) can be found in the
fact sheet (pdf).
Development and installationThe installation of new phones aboard Air Force One was part of a larger, 81 million dollar contract that was
awarded to L-3 Communications in 2009. This contract included the
installation of Airborne Information Management Systems (AIMS) hardware and software. It modernized the on-board communication systems and replaced outdated analog systems, providing fixed bandwidth switching and integrated secure/non-secure video teleconferencing. Also included was the installation of seamless passenger information interfaces throughout the VC-25 aircraft that serve as Air Force One.
It seems that the Airborne Executive Phone (AEP) was originally developed by Telecore Inc., as can be read in the
resume of someone who made a video presentation of this device (he did the same for the Senior Leadership Airborne Information Management System of L-3 Communications). Telecore is the company that manufactures the
IST-2 telephone for the
Defense Red Switch Network (DRSN), which is also a single device that can be used for both secure and non-secure calls. Probably Telecore sold the AEP to L-3 Communications.
Secure and non-secure callsAs we can see in the L-3 Communications advertisement, secure calls are indicated by a red background in the display and non-secure calls by a green one. This corresponds with two lights on the back of the handset: a green light which is on when the call is non-secure, and a red light that will indicate when it's a secure call over a highly encrypted line.

release to whom Obama was talking on this occasion.

The new Airborne Executive Phones are also installed in the smaller
Boeing C-32, a modified Boeing 757, which gets the air traffic call sign
Air Force Two when it is carrying the vice-president of the United States. Sometimes this plane is also
used by the president, and then serves as Air Force One, like for example for a trip on July 17, 2014 to the Port of Wilmington in Delaware:
President Obama talks on the phone with president Petro Poroshenko of Ukraine
about the Malaysia Airlines plane crash in eastern Ukraine, July 17, 2014.
Here we see the new phone in gray, and as Obama's finger is covering
the red light, and the green light is off, it seems a secure call.

Initially, Air Force One had sets of two telephone handsets installed all over the plane. These consisted of a cradle and an old-fashioned, so-called G-style handset, one in white and one in beige. The white handset was for non-secure calls and the beige one for phonecalls over a secure line. These phones were introduced on the previous plane that served as Air Force One, during the presidency of Ronald Reagan(!).

Air Force One on their way to the NAACP convention in New York. July 2009.
In this picture we see the phones that were previously used.

After the new Executive Voice over Secure IP (VoSIP) telephone network was installed in 2007-2008, which connects the White House with some of the most senior policy makers, the
Cisco 7975G Unified IP Phone used for this network was also placed in Air Force One, where the big device was somewhat out of place:

Now, all these three different phones have been replaced by a single Airborne Executive Phone, which connects to both ordinary and highly secure telephone networks.
