Introduction

MessengerCTI.Mobile Slican Software is mobile application dedicated for Android operating system, which allow to make incoming or outgoing calls, access to phone book, call history, view status of other subscribers and chat.
Application can work together alongside desk phone and smartphone already in use by PBX subscriber.

Application have advantage of being integrated with phone book saved in PBX. MessengerCTI.Mobile is using phone book stored in PBX but phone book entries can be modified only by using system phone or by computer with MessengerCTI.Desktop application or WebCTI. Additionaly MessengerCTI.Mobile Slican software operates as internal messenger-chat. Messenger can be use by all subscribers of particular PBX if required licenses are supplied.

Application advantages

Basic functionalities

Using a smartphone, the application user gains mobility and still has the option of using the PBX as an internal subscriber.

VoIP and GSM client MessengerCTI.Mobileparallel telephone, associated with the desk telephone equipment, landline (FXS, CTS, SIP). The application can work as a VoIP or GSM client. The user decides on which device to answer the call and make the call - phone or smartphone. A new feature is the ability to use the application as a standalone phone in NCP PBXes (from PBX firmware version 1.11). The CTIuserPlus license is required for its proper operation.

Configuration in VoIP mode - basic configuration for using the application. Both conducted calls and other information, e.g. about the caller's number, contacts in the directory, subscriber statuses, chats - are sent via the IP network (WiFi, Internet LTE/HSPA)

Configuration in the GSM mode - it is most often used if the access to the IP network or the Internet in a given location is weak (insufficient for making VoIP calls) or unstable. All information and signaling - are still sent via the IP network (WiFi, LTE / HSPA), but the calls themselves are carried out by the GSM operator. With poor quality of IP transmission, it should be taken into account that information may not always be displayed.

Switching between VoIP and GSM mode can be performed by the user from the application level (provided that he has the appropriate configuration on the PBX).

Contact book

A great advantage of the software is easy and convenient access to contacts from the PBX telephone books and displaying them on the user's smartphone. MessengerCTI.Mobile uses only the books stored in the PBX. Contacts can be grouped according to user requirements. Entering new subscribers and modifying existing entries can be made both from the system phone and in a more convenient way, from a computer - MessengerCTI.Desktop or WebCTI. The modification is visible immediately after its introduction. Access to the directory allows you to easily and conveniently search for the number of the person you want to call in the database. On the other hand, during incoming calls, clear information about the caller is displayed on the smartphone screen.

Call history The user of the program has access to the history of all his calls, both received and missed. It is saved in the Slican central. Using MessengerCTI, you can display it, obtain information about the order of calls, date and time of their execution, as well as about the sum of missed calls made from the same number.

CallCenter In conjunction with NCP PBXes for Call Center agents, the functionality of handling queues has been introduced. It allows e.g. logging in to one of them, viewing its status, answering and making calls, calling back lost and abandoned calls, enabling the status of temporary breaks in work.

Text messages

Using MessengerCTI.Mobile, you can send text information - from an internal communicator (chat) via a computer network - to another person who has MessengerCTI.Desktop or MessengerCTI.Mobile. The chat can be used by all subscribers of a given PBX and PBXes linked to it with the eSSL ver.2 system. This functionality is particularly attractive for those companies that, having Slican exchanges, do not allow the use of public messengers for security reasons. To ensure parallel access from different devices (computer, smartphone), chat history is saved directly in the PBX and synchronized with the MessengerCTI applications on an ongoing basis. An extension of this functionality is the ability to chat with many users at the same time, i.e. the so-called text conference.

Text and voice conferencing

A functionality that allows you to exchange messages / talk to many users at the same time.

File transfer Between MessengerCTI application users (desktop, mobile) it is possible to send files, e.g. photos, documents

Location Sharing

Due to mobility - the user can make the observation of his location available to selected people. An authorized person gains the ability to observe its location.

Support for cameras and DPH.IP doorphone

The introduction of DPH.IP doorphones with camera support for sale forced the creation of an option for displaying video images from them. Such a possibility was introduced in the MessengerCTI.Mobile application. In the case of a connection from the doorphone to the application user, the image from his camera appears in the window. After receiving and carrying out the call, and without the need to talk to the person at the doorphone, only after visual identification, you can open the door, gate or barrier using a special button. Also in the opposite direction, when calling the doorphone or any other extension number associated with the camera, the image from the camera appears on the monitor screen. This allows for temporary observation of the surroundings of the installed camera, e.g. the person we are calling. It is also possible to select and observe the image from any camera without the need to make a connection, just by indicating the associated icon in the application. Using MessengerCTI.Mobile it is also possible to use cameras from other manufacturers, but they must support video formats and codecs compatible with VLC application libraries. Opening the door using the context menu or widget is available only after starting the ACS system.

Works with the desktop version

The application can also be used in parallel and synchronized with MessengerCTI.Desktop, i.e. the version for a computer with Windows.

Minimum requirements

MessengerCTI.Mobile application - is available to download from Google Play store.

For installing application minimum requirements must be met:

• Android operating system
  • minimum version: KitKat 4.4.4
  • minimum recommended version: Nougat 7.0
  • PBX and application must have access to internet

Phone with lower version of operating system then 4.4.4 won't be able to install application.

Application installation

MessengerCTI.Mobile usage is licensed do purchasing of proper license is required. Purchased serial code is used during PBX configuration, serial code defines number of users that are able to use application. Application licensing doesn't interfere with installation. During the installation, you are prompted to provide some permissions and change phone settings. They may differ, depending on the Android version and phone type. You can accept them all or select only those related to the functionalities that will be used:

• Camera - for scanning the QR code and taking and sending photos
• Location - to share the location
• Microphone - for making calls in VoIP mode
• Internal storage - for saving photos, transferring files and using the clipboard
• Telephone - to use the application in GSM mode
• Contacts - for copying contacts to the local phone database (only used in some versions of the application)
• Displaying above other applications - should be made available so that you can answer the call correctly when the application is, for example, dormant
• Disable battery optimization - Battery optimization for the app must be disabled to prevent it from going into deep sleep

After installing application, it must be configured for connecting to PBX: Settings->Account (described below).

Starting application

MessengerCTI.Mobile application runs just like any other application working on Android operating system. During startup application is logging to PBX(according to setting from Settings->Account tab). After successful login synchronising between application and PBX starts(call history and chat history).

Configuring application

For proper communication between application and PBX, CTI account information and other functions must be configured properly. Configuration menu is placed in bottom left corner of application window. From drop down menu Settings menu can be chosen.

Settings

Fields required for configuration can be found here:account, notifications, handy numbers.

Supporting messages and calls

For call between two users necessary are:

• proper account configuration of application and PBX
• full connection between application and PBX(full data synchronisation of application with PBX) - application icon should have green color
• installed Slican system phone, VoIP or analog phone for IPx, MAC or NCP PBX or configured MessengerCTI subscriber((only NCP PBX)

Making calls

Two ways of making calls:

• from Contacts tab - choosing subscriber from particular group (if applicable), or from "All contacts" group. Call is made by touching contact tab, then choosing icon from drop down menu.
• from Contacts tab- searching for contact name in Search field by using keyboard then touching lower right corner of keyboard

• from Last/Recent - find subscriber which we had shared call(he called or we called him) and then make call by touching middle part of contact tab and choosing action from drop down menu

• from Search field tab- searching for phone number in Search field by by typing the phone number directly from the keyboard, and then tapping the green receiver on the right

Configuration in VoIP mode - basic configuration for using the application. Both conducted calls and other information, e.g. about the caller's number, contacts in the directory, subscriber statuses, chats - are sent via the IP network (WiFi, Internet - HSPA, LTE)

Configuration in the GSM mode - it is most often used if the access to the IP network or the Internet in a given location is weak (insufficient for making VoIP calls) or unstable. All information and signaling - are still sent via the IP network (WiFi, Internet - HSPA, LTE) but the calls themselves are carried out by the GSM operator. With poor quality of IP transmission, it should be taken into account that information may not always be displayed.

Switching between VoIP and GSM mode can be performed by the user from the application level (provided that he has the appropriate configuration on the PBX). Due to that reason, required city line for PBX must be at least ISDN BRA. The presented connection details on the smartphone display differ depending on the mode of its connection. The connection looks different in VoIP mode than in GSM mode due to the need to use the native telephone dialer. An example of an outgoing call made in VoIP configuration.

Outgoing call made in VoIP configuration.

Incoming calls

Incoming calls are displayed with a call popup and ringtone configured in the app's notification settings. Calls are answered by moving the icon with the green handset, if the phone was turned off, or by pressing the green button. If we want to reject the call, it can be done by moving the red handset or pressing the red button. If additional pop-up numbers have been set, the call can be forwarded to them by moving the icon with the pop-up number. The process of accepting incoming calls in the GSM mode consists in making a return call via the GSM line to the application access number defined by the PBX administrator.

You can direct an incoming call to another person. This can be done before answering the call or during it (with or without notification):

• instantly - by pressing the button with a quick contact, or
• select a number from your contacts list or recent calls

During a conversation, the user has the option of muting the microphone and/or turning on the loudspeaker mode.

The presented connection details on the smartphone display differ depending on the mode of its connection. The connection looks different in VoIP mode than in GSM mode (due to the need to use the phone's native dialer)

An example of an incoming call made in VoIP configuration

Connection setup and conversation are carried out entirely over the IP network (WiFi or LTE/HSPA Internet)

An example of an incoming call made in the GSM configuration (in the call interception mode)

This mode consists in the following:

The call for the user is an incoming call, but from the Slican PBX it is sent to the phone and the MessengerCTI application via the IP network - WiFi or Internet LTE/HSPA information about the incoming call and the MessengerCTI application initiates an outgoing call from the user's phone to the PBX (via the GSM operator) and there it joins a call, e.g. internal or from the city

In the call interception mode, the application user has more possibilities to manage the connection than in the parallel calling mode

During the conversation, the phone's GSM dialer window appears with the "tag" of the MessengerCTI application.

An example of an incoming call made in GSM configuration (in parallel calling mode)

In the parallel calling mode, information about the caller (via the IP network - WiFi, LTE/HSPA Internet) and connection setup (by the GSM operator) are initiated in parallel by the Slican PBX. During the call and conversation, the phone's GSM dialer window appears with the "badge" of the MessengerCTI application.

Missed calls are displayed with icon . Going to call history or calling back will clear information about amount of missed calls.

Calls to the Call Center Queue

Tab - allows you to handle calls directed to Call Center queues

The user who is an agent of the Call Center queue, in the CC tab, has the option of programming up to 4 individual buttons - login / logout from the selected queue, activation of the break.

With their help, he can perform the following actions:

• if he is permanently logged in to a given queue, then the button is permanently green in the appropriate queue (does not respond to touch)
• if he logs in/out to the queue - he logs in and out using the appropriate button and the button itself changes color from black and white to green
• if he goes on a break - it is with the help of a button whose color changes from black - white to yellow

If the user belongs to several queues, he or she can independently switch the preview of each of them using tabs (status of available agents, number of waiting in the queue, list of subscribers to be called back). If the user calls back to the person displayed in the List, he or she decides whether the call was successful (there are situations when the voicemail is answered, the caller is on another call, is out of network coverage, temporarily has no time, etc.)

A call to the Call Center queue is displayed as a normal incoming call. If there are unviewed missed calls in the tab, a red dot is displayed next to CC.

Use cases examples

MessengerCTI.Mobile application is useful tool for companies that employ mobile workers which requires constant access to phone with internal number of phone system.
These employees can be a good example:

• sales department - working in different locations, office <-> outside office
• service support - constant fieldwork
• remote worker - remote work
• mobile worker - working on vast area(production halls, vast areas) -where Wifi or DECT network range won't be adequate

Working in the local network and outside the local network without changing the MessengerCTI configuration

Changing the network source by the MessengerCTI.desktop or MessengerCTI.mobile user (e.g. LAN <--> Internet <--> LAN, work <--> travel <--> home) always entails changing the configuration of the application, i.e. changing the IP address of the PBX from local to public or vice versa (this situation does not occur if the user only uses LTE/HSPA internet).

In order to simplify the operation and configuration of the MessengerCTI application, you can use the functionality offered by many network routers. It allows a device with MessengerCTI (laptop, smartphone) to connect to the PBX, regardless of whether it is in the local network (LAN, WiFi) or outside it (other subnetworks, Internet, GSM-LTE). In routers, this functionality is called NAT hairpinning, NAT loopback, or NAT reflection. It enables access to the service via a public IP address, regardless of which network the user is currently in.

Example network:

• public address of the router (WAN on the router): address in the decimal system - 203.0.113.1 or domain address - voip.xxxxxx.pl
• local address of the router (LAN on the router, gateway): 192.168.1.1
• PBX address (NCP, IPx, MAC, CCT) in the LAN network: 192.168.1.2
• address of the user's laptop from MessengerCTI.desktop or smartphone from MessengerCTI.Mobile in the LAN: 192.168.1.100

If MessengerCTI from a laptop/smartphone from the local network from the address 192.168.1.100 sends a packet to the public address 203.0.113.1 (voip.xxxxxx.pl), the packet is normally directed to the default gateway - 192.168.1.1 (router). The hairpinning NAT router detects that 203.0.113.1 (voip.xxxxxx.pl) is the address of its WAN interface and treats the packet as if it originated from that interface. Determines the destination for this packet based on DNAT (port forwarding) rules. If the packet was sent to port 5529 (for VoIP: 5060, 8100-8300 for IPx, 10,000 - 20,000 for NCP) and there is a DNAT rule for this port directed to 192.168.1.2, then the PBX receives the packet at this address.

If appropriate DNAT rules exist, address translation is performed - the router rewrites the source local IP address in the packet to a public address. The laptop/smartphone (192.168.1.100) sends the packet, but the central office (192.168.1.2) receives it as coming from 203.0.113.1. When the control panel answers, the process is identical to the laptop/smartphone. In this way, bi-directional communication between a laptop/smartphone in the LAN via a public IP address is possible.

Installing beta version

"Beta" version contains new functionalities which will be added in next production version but not all of planned functions are implemented. This version also cointains fixes for error submited for earlier versions. It was initialy tested.
To install beta version:
