Secvoice 1.1611

This phone is suitable to be used by your circle of friends that want privacy or in an enterprise level.

We are deploying Secvoice at no cost with full security as a beta test product, this is the full product with full security, only limiting the conference call to 3 users, you need only to install and use.

NO warrantee and limited support is provided for this free application, at any time we can interrupt the service.

Our crypto phone allows:
* Point to point full duplex (talk and hear at the same time).
* Conference call up to 20 users in half duplex ( Walkie talkie mode ).
* Mode mute or silent. At any time you can interrupt the microphone.
* Can be used very well as a cell crypto, with excellent results in cellular telephony.
A NEW CONCEPT IN SECURITY.
Secvoice is a cryptophone that offers to our Clients the opportunity to have all software under their management in an easy way, creating all his security keys and bringing an enterprise class product with a low cost of maintenance and top security.

We can install and configure the server, the server have versions that scales to manage since few users to more than 40.000 users.

Secvoice is designed to offer to our Client the option to have under his control his own Secvoice server.
In this way, we deploy the Secvoice Server software to our Clients to use it in a private way.

Advantages:

The Enterprise Secvoice server is under our Client management.
* All security keys created by our Client.
* The physical local where the server is located is our Client choice.
* Who is or not is allowed to access the server is under our Client control.
* Cryptographic keys generation for the server access are under our Client control.
* Option to not have any kind of log, including the suppression of the register of all Client communications.
* The Secvoice server administrated by our Client communicates only with our Client smartphones.
* Once deployed, the server will be entirely managed by our Client, no way the server be remotely disabled by us.

OTHER PRODUCTS IN THE MARKET.

We compare our Enterprise Server with other products in the market:
* A easy to install server.
* A server can be configured to scale up to more than 40.000 users in one equipment.
* Almost no human intervention, means a low cost maintenance.
* Using only low complexity communication protocol ( UDP ).
* An Enterprise Key Server to deploy authentications keys, where our clients can generate all cryptographic keys.
