About Scall

Idea

RELAYONIT Scall is an application for the devices based on the Android operating system created to ensure the secure communication.

 

Through the use of end-to-end communication and encryption through SRTP, users can conduct secure conversations, video conferencing, and send messages using their phone.

 

Scall works over a local area network as well as a wide area network, where subscribers are connected by wide area network with NAT and firewall device types.

Step by step installation

#1

In order to use Scall, you must register a group account on our portal.

#2

As soon as payment for the product is completed, the Group Manager will be able to add users to the group.

#3

Added users receive an email with necessary information to download the application and log in to Scall.
As soon as a user is added, their name appears on the contact list of all the users within the same working group.
You can also add external contacts (outside of your organization)
At any time, the Group Manager can delete a user account of the working group and create another.

#4

The service will be continued in the next billing period if the full payment was made on the first day of the new period at the latest.

#5

In case of lack of payment, an email informing about the approaching end of the billing period will be sent to the Group Manager as well as an information about the end of services.

Quick start without commitments

RELAYONIT provides a dedicated communication server instance with access to the administration console. Users install only the communication software on their devices.

 

The process of starting the service is entirely independent – it is enough to choose the desired configuration and make a payement.

 

You don’t have to opt for the long-term subscription. The service is provided for 30 days. If you do not wish to continue, you just don’t pay for the next month.

Safety guarantee

Our solution is based on the „end-to-end” voice streaming (RPT protocol) secured by the SRTP protocol while the key exchange takes place through the GNU ZRTP protocol. It is necessary to have an access to Internet for both communicating users.

 

Network and cryptographic protocols used in our solution are: OTR, XMPP, SSL.

Principles of operation

The application allows to log in to an organization with the credentials obtained from the Group Manager. All registered contacts from the working group are downloaded automatically to the user’s contact list.

 

During dialing a voice connection, the cryptographic material is being exchanged via ZRTP protocol (Diffie-Hellman algorithm) and an Encrypted Real-time Transport Protocol session is being initiated.

 

The application offers the voice verification by using a four-sign SAS (Short Authentication String) Key. After the verification, an Retained Shared Secret is generated (hashed key information for SAS), which is cached for use during the next secured connection establishment.

Two models of cooperation

Scall is available in two options: Cloud and On-Site. The Cloud option provides an immediate access to the service, easy installation and application deployment. The service administrator can manage the user accounts of the organisation straight from the administration panel.

Unlimited encrypted calls, messages and videoconferences

No extra costs or investment of infrastructure

Fixed subscription fee
