DECT Headsets

Highest Security Level DECT Wireless Headsets

What is DECT? 

Digital Enhanced Cordless Telecommunications (DECT™) is the European Telecommunications Standards Institute’s (ESTI) standard for short-range cordless communications, adapted for voice, data, and networking applications. DECT technology has become the global standard for secure residential and business cordless phone communications. More than 110 countries have adopted the DECT system, with more than 100 million new devices sold annually. 

DECT Security Certification 

To meet the increased demand for secure communications, the DECT Forum, the international association of the wireless home and enterprise communication industry, has established the DECT Security Certification program. The certification program consists of requirements and security features, which, when implemented in a product, are validated by an accredited and independent test laboratory to show compliance. (DECT Security Certified products listed here)

3 Steps in the DECT™ Security Chain 

The DECT™ security chain is made up of three steps, as shown below:  

Pairing 

The first and vital step in the process is to bind the headset with the base. Pairing can be done over the air or for greater security by physically docking the headset into the base. This ensures the secret key shared during the process is exchanged via the charging contacts and not over the air.  

Authentication  

The secret key shared during the pairing process is used for each call to establish authentication between the subscribed headset and the base. A non-paired headset will not work with the base.  

Encryption 

The audio between the headset and the base is encrypted for each call so that intruders cannot read it – the encryption keys are regenerated every 60 seconds. 

DECT™ Security Evolution 

DECT security has evolved from the original security definition to new enhanced definitions called Step A, B, and C, each step offers increased security over the previous step. Each new security level includes all features of the prior level.  

  • DECT security – Authentication (DSAA)*, Encryption (DSC, 64 bit keys) 
  • DECT security step A – New features which correct certain vulnerabilities. Secure DECT certification. 
  • DECT security step B – New authentication using strong AES 128 bit encryption (DSAA2)* 
  • DECT security step C – Strong encryption of audio stream using AES 128 bit keys (DSC2)* 

* DSAA and DSC are the authentication and encryption algorithms defined in the DECT security standard ETSI EN 300 175-7 applicable for DECT security and DECT security step A. DSAA2 and DSC2 are the equivalent updated security algorithms for the next steps of DECT security, steps B and C. 

FIPS 140-2 

The Federal Information Processing Standard Publication 140-2 (FIPS 140-2) is a U.S. government computer and security standard used to approve cryptographic modules. Select DECT wireless headsets go one step further and utilize encryption algorithms (Advanced Encryption Standard (AES) 256-bit encryption) listed in FIPS 140-2 standards required by the US military and government. This level of security goes beyond DECT level C.  

Who Needs DECT Security Step C or FIPS 140-2 Level Security? 

Any industry that shares sensitive or private information over voice calls should strongly consider DECT wireless headsets with a higher level of security to include Financial, Banking, Healthcare, Insurance, Government, and Contact Centers.  

Secure DECT Wireless Headsets  

EPOS has a Protected Pairing process which transfers sensitive pairing data via the charging terminal of the IMPACT SDW 5000 base station instead of ‘over the air’. The security of the pairing process is further enhanced by the authentication algorithm (DSAA2), which uses AES-128-bit keys. The EPOS Impact SDW 5000 Series has reached step B in the DECT security level by implementing this enhanced algorithm. There are multiple wearing styles and connectivity options available to support individual preferences. Contact us for help in selecting the right EPOS Impact SDW 5000 model!

Yealink WH6X Series utilize DECT security level step C: Authentication – DSAA2, Encryption – DSC2 (128bit) and Cordless Advanced Technology: CAT-iq 2.0. They are available as stand alone DECT wireless headsets that connect to a computer or compatible IP phones that support USB headsets and they also have a new category of audio devices with their Yealink UC Workstation series.  

AES-128 encryption ensures secured communication when using Cisco Headset 560 Series available with a Standard or a Multibase. The Standard base supports single connectivity to a desk phone or a computer. The Multibase supports connectivity to a desk phone, computer, and mobile phone.

Military Grade Security 

These DECT wireless solutions utilize AES 256-bit keys for the very strongest level of encryption in professional headsets. The Jabra Engage 75 Series and Poly Savi 7300 Office models are also available in multiple wearing styles and connectivity options to support your team members regardless of work style and workspace. Contact us if you need help selecting the right wireless headsets for your team.

Poly Savi 7300 Office Series great solution for Return to Office

On March 5, 2021, we posted the Poly Savi 7300 Office Series Overview | NC Mic and Wireless Range Test video. It had been exactly a year since Call One, Inc. and Hello Direct, Inc. were sent to work from home due to the global pandemic. Today, we are getting requests for DECT Wireless headsets that achieve better density as some large organizations start heading back to the office.

Businesses are still reviewing and developing post-pandemic work models. Many will implement a hybrid work model that includes both in-office and remote work. For organizations that are going back full time and do not allow Bluetooth headsets on the premises, a dual connectivity DECT wireless headset that does not include Bluetooth is beneficial.

Desk Phone and Computer Connectivity

The Poly Savi 7300 Office Series offer desk phone and computer connectivity. They are compatible with existing EHS cables and Handset Lifter. Included in the box are both USB-A and USB-C cables for connecting to a computer’s USB-A or USB-C ports. The Savi 7300 Office Series are available in four models that include single and dual ear headband wearing styles. There are also Microsoft Teams Certified models.

What is the Savi 7300 Office Series?

The Savi 7300 Office Series is a new range of ultra-secure wireless DECT headsets for connection to a computer and/or desk phone. They do not replace any existing products. A key difference is security. The Savi 7300 Office Series headsets are designed to meet the highest level DECT Security Step C enhanced with Military level FIPS 140-2 listed features, such as 256-bit AES encryption. These are a great choice for financial, medical, government, contact centers, or anywhere sensitive conversations happen.

Acoustic Fence and Microsoft Teams Open Office

Additionally, the Savi 7300 Office Series headset uses a flexible noise-canceling microphone boom with Acoustic Fence technology, so conversations stay private. Acoustic Fence technology uses a second microphone on the ear cup to help identify and reduce background noise. The Savi 7300 Office Series meets the Microsoft Teams Open Office specification.

Microsoft Teams Certified

The Savi 7300 Office Series are the first Poly Microsoft Teams certified DECT™ headset with dedicated Microsoft Teams button. When pressed, the Teams button brings the Microsoft Teams desktop client to the front of the screen. If there is a message waiting or other notification the application will open to that screen – for a seamless Microsoft Teams experience.

Conference Feature for Training

Like all other Poly DECT Wireless headsets, the Savi 7300 Office Series supports multi headset conferencing. You can conference up to 3 additional headsets to a call in progress. This is a great feature for training Customer Service Representatives, contact center agents, or new team members. You can also mix desk phone and softphone calls together via Savi 7300 Office Series.

2x Better Density

The Savi 7300 Office Series makes more efficient use of the available spectrum by using the latest compression and modulation techniques as well as a new codec to provide up to 2x better density (compared to existing Poly and competitor devices) without impacting audio quality. There is no question that wireless headsets increase productivity. A challenge for large enterprises is deploying large numbers of wireless headsets without impacting performance. If you are looking to deploy large quantities of wireless headsets in single location, it’s best to contact an Authorized Poly Reseller like Call One, Inc. or Hello Direct to start a wireless density survey for your location/s.
