Call modes

PrivateGSM lets you to:

  • make secure calls to phone numbers and contacts using the PrivateGSM +801 prefix (not available on iOS). In this case, you do not need to manually open the main menu of PrivateGSM if the application is in background.
  • make secure calls to phone numbers and contacts without entering the PrivateGSM prefix directly from menu of the application.

Secure prefix number (Android and BlackBerry)

Calls with PrivateGSM are simply identified by the "+801" prefix in front of the number to be dialed including the international prefix without zeros. For example:
"+801 44 333 1234567"

+801

PrivateGSM prefix, including '+'

44

International country code for UK without zeros

333 1234567

Phone number

Note

For quick dialing we recommend you save numbers with the +801 prefix as "secure" contacts in your phone book.

Dial secure call with +801 prefix (not available on iOS)

Dialing a call with secure prefix +801 is not available on iPhone/iPad due to platform constraints.

Making secure calls with PrivateGSM is very easy. Dialing is as simple as prefixing your phone numbers with +801 as with international calls. With secure prefix you can make calls as you do with normal calls on your phone: insert phone number, select a contact from your address book or even from recent calls logs. Phone numbers prefixed with secure prefix +801 are detected by PrivateGSM which automatically starts a secure call.

Dialing a secure call

You can dial a secure call by entering the "+801" prefix before the number to be dialed, including the international country code without zeros, and press the Dial button.

Presence

1. Introduction

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

3.2. Contacts list

Due  to this features, on PrivateGSM we have three kinds of contacts list:

  1. Regular contact list: it contains all the contacts in your mobile.
  2. Favourites: a selection of contacts you choose to have apart, in order to make speed calls.
  3. Known: a list of the contacts that are recognised by the server and thus returned with a status
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 the unsecure Sip Trunk configured on your server. 

Enterprise version only!

 

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 

3.2.2. Client - Contacts lists

Up to PrivateGSM 11.x, two contact lists are available in PrivateGSM UI:

  • ALL: all contacts in device's addressbook, which are shown in PrivateGSM contact list
  • FAVORITES (iPhone only): contacts marked by end-user as "PrivateGSM favorites" are shown. This list is shown in a dedicated UI view
Starting with this version, there is one single contacts view. End-user can choose which list he wants to see in contacts list view:
  • BASE: list of all contacts to be shown in place of ALL. By default is phone address book as previously, but it could be substituted with favorites, remote address book, etc... See future enhancements.
  • KNOWN: show only known (registered or not) contacts, according to PrivateServer's knowledge
  • FAVORITES: contacts marked by end-user as "PrivateGSM favorites" are shown.
All the contact list are not editable. The BASE list has 1 item x contacts: if contact has multiple numbers he appears just once. When selecting it for secure call or in order to put the contact to the FAVORITES list (see below), end-user is prompted to choose the phone number to be used. The other lists (KNOWN and FAVORITES) shows 1 item x phone numbers.

 

 

3.2.3. Client - Favorites List

End-user can add and remove contacts from this list.

Favorites list contains single virtual phone number. If a contact has multiple numbers, end-user choose the specific phone number that we wants to add to favorites, so the same contact can appear in this list twice, with two different numbers.

3.2.4. Client - Known List

End-user can not edit this list.

Known list contains single virtual phone number, only if the phone number is registered on SIP server. The user can add a known number to the FAVORITES lists.

 We recognized three testing scenarios:

  1. Closed PrivateServer with Professional clients (Rendezvous style) : PBX_A
  2. Closed PrivateServer with Enterprise clients (Hofima/Rezzonico style): PBX_B
  3. Unsecurely open PrivateServer with Enterprise clients (PBX style): PBX_C 
  4. Securely open PrivateServer with Enterprise clients (ENI style): PBX_D

The # 3 has a working sip trunk towards some other pbx (might be a sip provider or an internal pbx as well).

Except where clearly stated into the test row it is intended that the test suite has to be run thrice: one for each scenario but for the first two that can be collapsed.

 

Dialing a secure call

You can make a secure call from the PrivateGSM menu by simply entering the number complete with international country code (i.e.: +44 for UK) and pressing the dial button.

Suggestion
