Here are descriptions of the more relevant changes in EVSS 3.3.

Platform changes

Presence and audio messages

With the present version we completed one milestone of the Suite. We are very glad to introduce the Presence and the Audio Messaging into EVSS 3.3.

Presence is the name for the user reachability, that is the status of the client we want to call. Thanks to the Presence it's now possible to know if a user is on line and can receive a secure call before calling it.

The Audio Messaging feature is one strong request from our customers that we gladly accepted. It's a dramatic improvement in the the look and feel of PrivateGSM because now the application can play localised audio messaging that pairs with the pop-up messages to notify the users. This modification let the user deal with the phone in a more natural fashion, ie without having to check on the screen how is progressing the call.

Audio messages speaks directly to the user to inform about the reasons behind a failed call. Audio messages are localised both on client and server side.

The two options combined create an astounding improved user experience.

PrivateServer changes

Audio Messages

Starting from this release you can configure the "data retention" policy for different types of historical data. These data will be automatically archived on the file system and thus removed from the operational database.

Administrators can dis/enable data archival and configure the retention period to keep the historical data online. Archived data can be exported/downloaded and removed from PrivateServer.

This version enables by default 1 month of data retention for SIP Sessions data, which are generally useful only for debugging and support purposes: if you want to keep them more time please change your configuration.

Localization

It is possible to configure RPM package repositories, then verify if any update is available and apply them to PrivateServer via web console.

CDR (Call Detailed Record) privacy option

PrivateServer can send periodic keepalive messages to clients, on per account basis. This is especially useful with network equipments or mobile operators that uses a short TCP-idle timeout, even shorter than 10 minutes, which is a critical conditions with iPhone devices.

Improved Network Segregation
