Services| Encrypted Voice Call

Encrypted Voice Service Overview

Voice transmission is easy to intercept with the recent technological advances. The only way to hide the information is to encrypt it. With the Encrypted Voice Service you have secure voice protection whenever and wherever a sensitive call needs to be placed. When an encrypted phone call is enabled on a mobile and it calls another encrypted-enabled mobile, the devices transparently and seamlessly authenticate and connect. All voice communication is then encrypted and sent over a secure data channel.

The Encrypted Voice service is facilitated by the Trust Center which is responsible for:

  • Assigning, storing and authenticating User IDs, TrustChip IDs and Device IDs.
  • Maintaining active directories of authenticated users, restricted to administrator-defined TrustGroups.
  • Facilitating secure communications between authenticated users belonging to the same TrustGroups.
  • Utilizing push technology to notify users of incoming communication.

Depending on the needs and customer preferences, the Encrypted Voice is offered in two different options:

  1. Hardware Edition (HE) via the KoolSpan TrustChip© hardware-anchored, microSD encryption engine.

    2. This option consists on the installation of the Koolspan Trustchip and the Koolspan TrustCall App into your mobile devices eliminating the risk of voice traffic intercepts across carrier infrastructures. Each TrustCall-enabled device is equipped with a TrustChip® microSD security processor to authenticate and secure communication between two entities. When a TrustCall-enabled phone calls another enabled phone, the devices transparently authenticate and connect. All voice communication is then encrypted and sent over a secure data channel. The entire process is facilitated by the Kryptic Mobile Trust Center’s secure server network, is seamless to the mobile device users. Our service representative will deploy this service for you at your location and convenience. We provide you with a dedicated technical support with your order.

  2. Virtual Edition (VE) – KoolSpan's hardware-anchored, software-based encryption engine

    3. This option provides secure voice communication utilizing the native hardware of the mobile device rather than an external encryption engine. TrustCall/VE's authentication, key management, and encryption functions are provisioned to the Trusted Execution environment (TEE) of the mobile device CPU, allowing for rapid VoIP communication, easy deployment, and minimal physical inventory to manage and track. This combination of software and hardware is significantly more secure than software-exclusive mobile security solutions.


The Encrypted Voice is a monthly service that works between two or more mobile devices such as iPhone, Android or Blackberry. Your mobile devices must have a data plan subscription with your existing phone carrier provider.
