Aplication structure

Introduction

MessengerCTI.Mobile Slican Software is mobile application dedicated for Android operating system. It integrates smartphone, computer and subscriber's desk phone. MessengerCTI.Mobile allows users making and receiving calls as PBX subscriber, transferring calls to another subscriber, using contact book, history of calls, conducting chat and text conferences, viewing phone and MessengerCTI status of other subscribers and transferring files. Video image preview function is available for PBX that support DPH.IP doorphones equipped with camera. Application supports calls related to Call Center queues - PBX subscribers/ agents are mobile and independent of their permanent workplace. Functionally, MessengerCTI.Mobile is fully synchronized with MessengerCTI.Desktop, so regardless of version used (mobile, desktop) it always ensures work with up-to-date data.

Warning! For proper operation of application and calls, following are required: permanent access to WiFi or Internet from smartphone with MessengerCTI.Mobile application permanent access to LAN and Internet for PBX if MessengerCTI.Mobile works via Internet - domain address or permanent public IP address of PBX, or if PBX is located in local network behind NAT - on edge router it is necessary to redirect some ports to its IP address. Description of port forwarding configuration is presented below in Ports and Protocols chapter MessengerCTI.userPlus license per user at PBX optional, depending on adopted configuration - license for VoIP subscribers in NCP or subscribers and VoIP channels in IPx, MAC, CCT exchanges

Basic Features

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

VoIP and GSM client

• MessengerCTI.Mobile - parallel telephone, associated with equipment of desk phone (FXS, CTS, SIP). Application can work as VoIP or GSM client. User decides on which device to answer call and make call - by desk phone or smartphone. Novelty is possibility of using application as standalone telephone in NCP (from firmware version 1.11). CTIuserPlus license is required for its correct operation.
• Configuration in VoIP mode - basic configuration for using application. Both calls made and other information, e.g. about the caller's number, contacts in book, subscriber status, chats - are sent over IP network (WiFi, LTE/ HSPA Internet)
• Configuration in GSM mode - it is most often used if access to IP network or Internet in given location is weak (insufficient for VoIP calls) or unstable. All information and signaling - are still sent via IP network (WiFi, LTE / HSPA), but calls themselves are carried out by GSM operator. With poor IP transmission quality, you should take into account that information may not always be displayed.

Switching between VoIP and GSM mode can be done by user from application configuration (if PBX is properly configured).

Phone Book

Big advantage of software is simple and convenient access to contact from phone books and displaying them on computer screen. MessengerCTI.Mobile can use only phone books from PBX. Contacts can be sorted according to user needs. Adding new subscribers and modification of existing entries can be done from CTS system phone or more conveniently, by using computer with MessengerCTI.Desktop or WebCTI. Modification of entry is visible instantly after adding it. Access to phone book allows to simply search numbers of contacts user want to call. On other hand, during incoming calls computer displaying will be showing clear information about calling person.

Call History

User has access to complete history of their calls, picked up and missed one. History is saved on Slican PBX. By using Messenger.CTI history can be displayed alongside information about order, time of calls and number of missed calls from particular number.

CallCenter (NCP PBX)

In conjunction with NCP for Call Center agents, queue handling functionality has been introduced. It allows agents to log in to them, view status, call back lost and abandoned calls, and turn on status of temporary work breaks.

Text messages

By MessengerCTI text information can be sent, from internal messenger (chat) through computer network to another person with MessengerCTI.Desktop or MessengerCTI.Mobile. Chat can be used by all subscribers of given PBX and other PBX linked with eSSL ver.2 system. This functionality is especially attractive for those companies which, having Slican PBXes, do not allow use of public communicators for security reasons. To ensure parallel access from various devices (computer, smartphone), chat history is saved directly in PBX and synchronized with MessengerCTI applications on ongoing basis. An extension of this functionality is possibility of conducting chat with many users simultaneously, i.e. so-called text conference.

Text and voice conferences

Functionality that allows to PBX messages / talk simultaneously with many users

Uploading files

It is possible to send files, e.g. photos, documents, between users of MessengerCTI application (desktop, mobile)

Location sharing

Due to mobility - user can turn on selected people observation of his location. Authorized person gains ability to observe its location.

Using cameras and DPH.IP doorphones

Introduction to sale of DPH.IP doorphones that include cameras allowed to solution that allows display of video from these cameras. Functionality was added with MessengerCTI.Mobile. While connecting to doorphone from software video from camera will appear in new window on computer display. After starting call and next finishing call, even after without talking to person standing beside doorphone, just after visual check user can open door, gate, barrier using dedicated button. Reverse is also true, calling to doorphone or another telephone associated with camera, computer display will show video from their cameras. This allow for temporary observation of neighborhood of installed camera, for example person we are calling. There is also option of watching video from any camera without making call, just using application icon. Thanks to MessengerCTI.Mobile user can preview video from camera of other manufacturers, but those devices have to support video formats, codec compatible with VLC application libraries.

Works with desktop version

Application can be used alongside and synchronized to MessengerCTI.Desktop, that is version for computer with Windows.

Minimum requirements

MessengerCTI.Mobile application is freely available - it can be downloaded from Google Play store..

For installing application minimum requirements must be met:

• Android operating system

  • 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.

Attention! While using for VoIP calls we recommended Android version 7.0 or higher due: better call stability option of automatic regaining voice connection after reloging to network or changing IP option of regulating microphone gain for VoIP calls

Warning! MessengerCTI.Mobile application works with IPx, MAC and CCT PBX with firmware version 6.53 or higher and NCP PBX 1.11 VoIP with application is supported for IPx, MAC and CCT with firmware 6.54 and NCP firmware 1.12

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

During installation, you are prompted to provide some permissions. You can approve all of them or select only those related to functionalities that will be used:

• Camera - for scanning QR code and taking and transferring photos
• Location - to share your location
• Microphone - for making VoIP calls

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, CCT, MAC, NCP PBX or configured MCTI subscriber (only NCP PBX)

Making calls

You can make calls in several ways:

• from Contacts tab - select subscriber from appropriate group (if such in PBX contacts are created) or directly from All contacts group. Call is made by tapping contact and then selecting Dial icon from drop-down menu
• from Last tab - you find from history we are interested in contacting subscriber (we had conversation with him, he called us or made call to him, we sent or received message from him). Call is made by tapping contact and then selecting Dial icon from drop-down menu
• in Search field by entering telephone number or subscriber's name directly from keypad, and then by tapping green receiver on right side
• from numeric keypad opened in lower right corner of Last tab

VoIP mode - basic configuration for using 'application. Both calls made and other information, e.g. about caller's number, contacts, subscriber status, chats - are sent over IP network (WiFi, Internet - HSPA, LTE)

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

Switching between VoIP and GSM mode can be done by user from application level (if PBX is properly configured).

Presented connection details on smartphone display differ depending on calls setting mode. VoIP call looks different than GSM call due to necessity to use native phone dialer.

Example of outgoing call made in VoIP mode:

Example of outgoing call made in GSM mode:

Incoming calls

Incoming call is signaled visually by pop-up call window and acoustically with bell configured in notification settings. Calls are answered (depending on whether display phone was turned off or not) by moving middle icon towards green handset or by pressing green one. If call is to be rejected, move icon towards red handset or by pressing red one.

We can redirect incoming call to another person. You can do it before answering call or during call (with or without notification):

• immediately - by pressing button with Quick transfer contact, or
• dialing number from list of contacts or recent calls

During call, user can mute microphone and/or turn on speakerphone mode.

Presented connection details on smartphone display differ depending on calls setting mode. VoIP call looks different than GSM call due to necessity to use native phone dialer.

Example of incoming call made in VoIP mode

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

Example of incoming call made in GSM (Call pickup mode)

This mode is based on following:

• connection for user is incoming connection from Slican PBX (information about connection is sent to smartphone and MessengerCTI application via IP network - WiFi or LTE/HSPA Internet)
• physically, MessengerCTI application initiates outgoing call from user's smartphone to PBX (by GSM provider) and joins connection there, e.g. internal or external

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

During call, GSM dialer window with MessengerCTI application "badge" appears.

Example of incoming call made in GSM (Parallel calling mode)

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

In call history, missed call is symbolized in application with icon . Going to Last tab or callback call clears information about number of missed calls.

Calls to Call Center queue

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

User who is agent of Call Center queue, in CC tab, can program up to 4 individual buttons, e.g. logging in / logging out from selected queue, switching on break.

With button help, user can perform appropriate activities:

• if he is permanently logged in to given queue, button is permanently green at appropriate queue (it does not respond to touch)
• if he logs in / out of queue - he uses appropriate button to log in and out and button changes color from black and white to green
• if he go on break at work - he uses button whose color changes from black - white to yellow

If user belongs to several queues, he can independently, using tabs, switch preview of each of them (status of available agents, number of waiting in queue, list of call-back subscribers)

If user calls back to person displayed in List, he independently decides whether given calls was successful (there are situations when voicemail is reported, called back carries out another conversation, destination subscriber is out of network range, temporarily lacks time, etc.)

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

Chat

Application allow to send and receive text messages between MessengerCTI.Desktop/ Mobile application user (internal chat).

To send message, click:

• application status icon on left side or message/chat icon on right side of username
• in username and from pop-up menu, select option Chat/History

Receiving new message is signaled by sound signal, information on bar/ in the notification window and appropriate icon next to username in call history.

If user uses both MessengerCTI.Mobile and Desktop versions, history of messages between aplications is synchronized.

Operation in local network and outside local network without changing MessengerCTI configuration

If MessengerCTI.desktop or MessengerCTI.mobile application user is on move, his IP network source may change (np. LAN <--> Internet LTE, HSPA <--> LAN, work <--> travel <--> home) it may results need to change application configuration, i.e. change IP address of PBX from local to public or vice versa (situation does not take place if user uses LTE/HSPA internet only)

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

Sample network:

• router's public address (router's WAN): decimal address - 203.0.113.1 or domain address - voip.xxxxxx.com
• router's local address (router's LAN, gateway): 192.168.1.1
• PBX address (NCP, IPx, MAC, CCT) in LAN network: 192.168.1.2
• user's notebook address with MessengerCTI.Desktop or smartphone with MessengerCTI.Mobile in LAN: 192.168.1.100

If MessengerCTI from notebook/ smartphone from local network - IP address 192.168.1.100 - send packets to public address 203.0.113.1 (voip.xxxxxx.com), packets are routed to default gateway - 192.168.1.1 (router) by default. NAT hairpinning router detects that 203.0.113.1 (voip.xxxxxx.com) is address of its WAN interface and treats packets as if it were coming to that interface. Determines destination for those packets based on DNAT (port forwarding) rules. If packets have been sent to port 5529 (for VoIP: 5060, 8100-8300 for IPx, 10,000 - 20,000 for NCP) and there is DNAT rule for this port directed to 192.168.1.2, then PBX receives packets at this address.

If appropriate DNAT rules exist, address translation is performed - router rewrites source local IP address in packets to public address. Notebook/ smartphone (192.168.1.100) sends packets, and PBX (192.168.1.2) receives it as coming from 203.0.113.1. When PBX responds, process is same as for notebook/ smartphone. In this way, two-way communication between notebook/ smartphone in LAN via public IP address is possible.

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
