PrivateWave
Quick Start Guide for Android

This guide provides you easy step-by-step instructions to help you get started with PrivateWave .

Secure calls with  PrivateWave

Calling with PrivateWave  is a very easy task. You can both use your contact list or directly dial a number using the dialpad.

 

To make a secure call, you and the called party must have PrivateWave software running on the mobile device, be connected to the Internet and to the same PrivateServer .

Calling by Contacts list

Select Contacts tab from the tab bar, tap on the contact you want to call and select the contact number associated with PrivateServer .
figure 2. your address book is shared with application

As you can see in figure 2. your address book is shared with application each contact can show a coloured ball at its left, or nothing at all. These are status marker and they represent the Presence Status for each contact.

Presence

The Presence avoid users to call contacts who are not reachable, eg: because they do not have PrivateWave  activated and/or connected. The main value of this feature is to improve user experience suggesting the possible outcome of a call.

Contacts lists

PrivateWave  gives you access to three different kind of lists:
  • ALL: it lists all the contacts which are in the mobile address book, ordering them in the very same way.
  • KNOWN: it shows only known contacts (registered or not) according to PrivateServer 's knowledge. This means it is a list of the contacts that are recognised by the server and thus can have a status.
  • FAVOURITES: it reads the contacts marked by you as " PrivateWave favorites". It's a selection of contacts you choose to have apart, in order to make speed calls.
Each list may show a Contact status beside each contact. The contact status legenda is shown below:

Contact status

OnlineThe contact is reachable. You can make a secure call to the user.
OfflineThe contact is not reachable, because is not under network coverage or is offline. You can try to make a secure call but the call will likely fail
Warning

The contact is not reachable using a full secure call, but you can call him using one Sip Trunk configured on your server. 

ErrorThere is a comunication error between your phone and the server. The contact status is unknown, anyway you can try to make a secure call

 

Calling by dialpad

You can make a secure call to any arbitrary number (presuming that the call peer has PrivateWave  connected) from PrivateWave  menu by simply entering the number with the on-screen keypad and pressing the dial (green) button.

Receiving a secure call with  PrivateWave

Once PrivateWave  is installed and all the settings are correctly configured on your device you are able to receive a secure call. When a secure call arrives to your device a notification bar will be shown on the top of the screen. Tap on the notification to bring the application in foreground, then answer or decline the call from the application. After the system have exchanged and verified the security keys the you can start the conversation.

Call status

To establish a call PrivateWave  completes three phases shown by two icons:

Call status icons

Red light

Starting the connection

Connection not yet established. This step may take several seconds

Green light

Secure call established

Connection established and secure. You can now speak securely

Checking your security

A PrivateWave  call is always encrypted. The call is automatically secured during the call setup. As soon as the call is established you can immediately start to talk securely with your call peer.

The security of the call is based on a digital certificate verification on the SIP/TLS server. If a certificate error appears check whether the date of your phone is correct. If the date is correct it is possible that the certificate is wrong, misconfigured or expired or that your phone is undergoing a security attack. In these cases always contact your system administrator.

 

History

Every event performed or received on your PrivateWave  is listed into the "History" tab, which can be displayed by pressing "Recent" icon on the tab bar.

figure 8. event detail

By clicking on this icon you have access to event's details (cfr figure 8. event detail). 

Secure Messages

You can communicate with your peers by text messages using the Secure Messages System which provides Secure Messages. A Secure Message is a text message that travels into the same encrypted architecture of the Secure Call. 

The maximum length of a single message is 160 character

  • If PrivateWave  is configured with PIN disabled each Secure Message has a time validity, after which it expires. Expiration means that the Secure Message content is no longer readable and it's gone for good. Instead of message content you'd rather read "Message received" or "Message sent".
  • if PrivateWave  is configured with PIN enabled each Secure Message is persistent.

 If you disable PIN or use duress code all messages and calls history will be deleted from  PrivateWave  .
