The present manual offers a guide to manage the PrivateServer that (among PrivateGSM clients) composes the Enterprise Voice Security Suite: the solution that ensures the safety and inviolability of voice communications on both mobile and fixed phones by offering a secure voice convergence system in a corporate network.


An installed and on-line PrivateServer.


The present manual is intended for a Secure VoIP Service Administrator. It explains how to manage the day-by-day procedure for:

Intended audience

This guide is intended for PBX administrators who will provide secure call service by PrivateServer. No specific background is needed

This manual won't explain how to install the server itself. For such knowledge please refer to the PrivateServer Administration Manual.


In the present documentation you'll meet the following terms:


private branch exchange (PBX) is a telephone exchange that serves a particular business or office, as opposed to one that a common carrier or telephone company operates for many businesses or for the general public. 

PBXs make connections among the internal telephones of a private organization—usually a business—and also connect them to the public switched telephone network (PSTN) via trunk lines.


trunk line is a circuit connecting telephone switchboards (or other switching equipment), as distinguished from local loop circuit which extends from telephone exchange switching equipment to individual telephones or information origination/termination equipment.

When dealing with a private branch exchange (PBX), trunk lines are the phone lines coming into the PBX from the telephone provider. This differentiates these incoming lines from extension lines that connect the PBX to (usually) individual phone sets. 

Secure Call

Secure Call is a voice connection which can't be wiretapped. It runs on the Voice Over IP (VoIP) communication protocol and can be used in two classification models:

  • End to end
  • End to site
The end to end provides the highest security level but can be used only between two PrivateGSM equipped devices.
The end to site provides a strong security level and can be used among two or more PrivateGSM equipped devices and/or among SNOM 300 landline devices or also for connecting other non-secure PBX. In this case the call is secured in the PrivateGSM to PrivateServer leg but is not secured on the PrivateServer to PBX one.


PrivateServer is the PBX committed to perform Secure Calls both end to end and end to site. It differs from a standard PBX for exposing just the Secure Call service to VoIP PrivateGSM clients and can be connected to a standard PBX via SIP Trunks if configured accordingly.


PrivateGSM is the VoIP client for Secure Calls connections. It has to be used along with PrivateServer and is deployed in two different models to perform two different secure models:

  • PrivateGSM Professional: used for end to end communications
  • PrivateGSM Enterprise: used for end to site communications

Because of the security model each one implements, the two versions can't communicate with each other. Plus, the PrivateGSM Professional edition can only perform direct calls to another PrivateGSM Professional Devices. On the other hand the PrivateGSM Enterprise Edition can also perform Conference Calls and Three-Way Calls.

Conference Rooms

The conference call is a call in which more than one person can partecipate. The conference calls are usually defined as "rooms" which access can be limted by time settings or pass code. In PrivateServer the conference calls can be provided on a Secure Call base if using the PrivateGSM Enterprise Edition only.

SIP Accounts

The SIP Accounts are the users account on the PrivateServer. Without configuring such accounts none can place or receive Secure Calls.

Automatic Activation 

The Automatic Activation is the way of create new users automatically without any need they interact with anybody. As from user's side the procedure is that he/she gets first an invite SMS useful to download the application PrivateGSM and then a configuration SMS which provides automatic configuration of the client itself. All the user has to do is follow the links into both the SMSes and it goes automatically on line.


The Provisioning is the configuration needed for delivering both for the PrivateGSM application and its configuration and nowadays it's used by the Automatic Activation only.
