Download and installation

KCTI 4 can be downloaded for free from the Download page of the official KalliopePBX website.

The user can then go to the configuration page to select which version to open each time (as long as the corresponding license has been activated on KalliopePBX V4). KCTI Free, Pro, or Phone are different modes of the same software.

Note

Installation does not prompt for any activation keys. Instead, the application will automatically check for the correct license on KalliopePBX every time it is opened.

Unlike KCTI 4 Free, KCTI 4 Pro and Phone require a specific license to be activated on KalliopePBX V4 for each workstation. The KCTI 4 Phone license also includes KCTI 4 Pro. The user can choose their desired mode from the configuration page.

For instructions on how to activate the KCTI 4 Pro or KCTI 4 Phone licenses, see the licenses page.

System requirements:

Windows:

Windows 10 or later
Sound card (for KCTI Phone)
2 GB RAM
100 MB of free disk space

MAC:

macOS: Ventura, Monteray and BigSur
recommended: Apple hardware from 2013 or later

Linux:

Ubuntu 22.04 and 20.04

To install the application on Windows, simply open the executable file and follow the instructions.

Note

In case the SIP service of the central unit is exposed on a different IP from the CTI connection one, or on a different port from the standard one (5060) it is necessary to set on the KalliopePBX one or both of the following custom placeholders inside the Provisioning panel: %%_KPHONE_SIP_REGISTRAR_IP%% and %%_KPHONE_SIP_REGISTRAR_PORT%%% . This configuration is normally necessary when the SIP service is exposed to the public through a Session Border Controller that uses a different IP from the one on which the PBX is reachable, while it is not necessary if the PBX and the SBC are NATed on the same public IP, each one for the ports of its competence (TCP/5039 and TCP/5222 for the CTI and Chat components, towards Kalliope, and SIP + RTP for voice, towards the SBC).

KalliopeCTI Mobile

Introduction

For those who need to always be on call, Kalliope has designed the KalliopeCTI mobile app for Android and iOS.

The KalliopeCTI mobile app is an optional product that lets you access telephone and UC services even outside your office through your extension number, using the company lines.

To guarantee stability and improve conversation quality, KalliopeCTI mobile lets you choose how to handle your calls: based on data traffic availability, you can choose whether to use the GSM network or use the app in softphone mode.

KalliopeCTI mobile lets you call using three different modes:

Click-to-call: the call will be handled through the desk phone associated with your extension;
Call-back: call from your smartphone using Kalliope lines;
Softphone: using an integrated SIP telephone engine, your smartphone will register to KalliopePBX like any other IP client.

KalliopeCTI mobile is available on Playstore and App Store.

View the policy on Processing of users’ personal data

Note

Each extension can only be linked to one KCTI account.

Initial configuration

In order to use the KalliopeCTI mobile app you must first:

Enable “KCTI Mobile App” in the account settings

Note

Only one account per extension may be enabled to use the mobile app

Assign one of the following KalliopeCTI licenses to the user:
- KalliopeCTI Pro license -> enables the use of the KalliopeCTI mobile app only in callback mode (GSM™)
- KalliopeCTI Phone license -> enables the use of the KalliopeCTI mobile app in both softphone and callback mode
If you wish to externally access the company network with the mobile app, you will need to publish the following KalliopePBX ports

Note

It is recommended to not expose the central unit’s SIP service on the public in a direct way that can be reached from arbitrary IPs, but to use a Session Border Controller that can properly protect the central unit from intrusion attempts from outside)

TCP 5039 port for CTI services
TCP 5222 port for XMPP chat services
UDP for SIP service port as configured in the “SIP settings” page (only for softphone mode, default value is ‘5060’)
UDP 10000-20000 ports interval for RTP streams (only for softphone mode)

Also, it is necessary that the KalliopePBX can send messages to the push notification servers of Apple and Google, so the reachability by the KalliopePBX of the following addresses must be guaranteed:

iOS: api.push.apple.com (HTTPS, port TCP/443)
Android: fcm.googleapis.com (HTTPS, port TCP/443)

Since these hosts may resolve different IPs over time, it is recommended that no filters be applied to HTTPS traffic exiting KalliopePBX.

In addition, in order for mobile devices running the KalliopeCTI Mobile APP to receive notifications, they must be connected and reachable by the sending services. For more information about the flows that must be ensured, please refer to the official documentation of:

Note

In order to avoid abnormal behavior in sending incoming/ending call notifications to clients, it is necessary that each user is logged in on a single device, because each SIP account (and therefore associated user) can be associated with a unique Firebase token (used to identify the recipient of the notifications).

Note

In case the central unit SIP service is exposed on a different IP than the CTI connection IP, or on a different port than the standard one (5060), it is necessary to set on the KalliopePBX one or both of the following custom placeholders within the Provisioning panel: %%_KPHONE_SIP_REGISTRAR_IP%% and %%_KPHONE_SIP_REGISTRAR_PORT%%%. This configuration is normally necessary when the SIP service is exposed to the public through a Session Border Controller that uses a different IP from the one on which the PBX is reachable, while it is not necessary if the PBX and the SBC are natted on the same public IP, each one for the ports of its competence (TCP/5039 and TCP/5222 for the CTI and Chat components, towards Kalliope, and SIP + RTP for voice, towards the SBC).

Kalliope Call Center is an optional KalliopePBX module that adds advanced features specially designed for call centers.

The main features included in Kalliope Call Center are:

Kalliope Supervisor Panel
Call Center CDR
Call Tagging
Spy/Whisper/Barge services
Queue position reservation and automatic callback

This page describes the Kalliope Supervisor Panel. For further information on the other features included in Kalliope Call Center, see the user manual.

Kalliope Supervisor Panel

The Kalliope Supervisor Panel software lets a user access queue statistics based on their role, monitor and change the state of the operators, and manage dynamic operators.

When first opening the application, you will need to go to the Settings page and insert the credentials of the extension. The system will automatically check for the required Call Center license and the role of the user (supervisor or operator).

Note

Installation does not prompt for any activation keys. Instead, the application will automatically check for the correct license on KalliopePBX every time it is opened.

Menu bar

The menu bar lets you select the Settings sub-menu.

The Settings menu contains the following items:

Connect to KalliopePBX: start the connection with KalliopePBX
Disconnect from KalliopePBX: interrupt the connection with KalliopePBX
Fullscreen: view the application in fullscreen mode (shortcut: F11)
Settings: opens the Settings page
Quit: close the application (shortcut: CTRL+Q)

Settings page

From the menu bar you can open the configuration page, which consists of two parts: Credentials and Customize logo.

Credentials

This section lets you configure the following parameters:

KalliopePBX IP address: the IP address of the KalliopePBX the application should connect to
Username: the name assigned to the user
Password: the password assigned to the user

Note

The username and password are the same as the credentials on the System -> KCTI/Web users page on KalliopePBX V4.

Customize logo

This section lets you upload an image file containing the custom logo that will be displayed in the main screen of the application instead of the KalliopeCC logo.

Main screen

The main Kalliope Supervisor Panel screen is divided in thee sections:

Logo bar
Statistics panel
Operator panel

The first has a set size and cannot be hidden, while the other two can be expanded or reduced and can be set to completely fill the main screen. This can be useful if, for example, you wish to only view aggregated data without seeing the names of every operator.

The main screen changes depending on whether the logged-in user is a supervisor or an operator. A supervisor will see information on all active queues on the PBX and will have permissions to pause and assign queues to every operator. An operator will only see the queues and statistics that concern them.

The three sections are detailed below.

Vediamo, di seguito, le singole le sezioni in dettaglio.

Time and logo bar

As explained above, this section can be partly customized by changing the logo from the Settings page.

The time and logo bar displays the following information:

The KalliopeCCenter logo or the custom logo uploaded by the user
Date and time
The total number of calls in every queue
Time range selection: from the drop-down menu you can choose the time range for which to display aggregated data in the section below

Statistics panel

This columns of this table display information on each active queue on the PBX.

The rows display data on:

Users in the queue: dynamically updates when a user enters or exits the queue
Oldest call in the queue: the time, in seconds, that the oldest call has been in the queue;
Average waiting time: always refers to the last hour regardless of the selected time range and updates every 5 minutes by automatically downloading and analyzing the month’s CDR;
Active operators: reports the state of the operators in real-time; the first number is the number of active registered operators (green BLF), the second the number of busy registered operators (red BLF), the third the number of paused registered operators (orange BLF), and the fourth the number of operators whose state is unavailable (gray BLF);
Missed calls (in the selected range): varies depending on the time range selected in the drop-down menu;
Answered calls (in the selected range): varies depending on the range of time selected in the drop-down menu;
Average waiting time (in the selected range): varies depending on the range of time selected in the drop-down menu;
Average conversation time (in the selected range): varies depending on the range of time selected in the drop-down menu;

_images/450px-Pannello_statisticheCC.png

Operator panel

The first column shows the registered operators on the PBX, the second the corresponding BLF state, and the remaining ones correspond to each queue, as with the statistics panel.

Each row corresponds to a single operator and their data for each queue they are statically or dynamically assigned to. This table gives an overview of the situation across all queues.

Each cell corresponding to a specific operator and a specific queue gives the supervisor important information.

The color of the cell indicates the state of the operator. If the operator is active, the cell is green; if the operator is paused, the cell is orange. Similarly, the button will change between Pause and Reactivate.

Note

Operators are only able to change their own status, while supervisors can act on all operators.

Each cell also displays the following information:

The number of answered calls in the selected time range, on the top right;
Whether the operator is static or dynamic on that queue (in the latter case, a “D” will be displayed next to the number of answered calls);
Time operating on the queue: the amount of time since the status was last changed from active to pause or vice versa;
Time of the last served call.

Adding dynamic operators

A dynamic operator is a user that has been temporarily assigned to one or more queues by a supervisor. Unlike static operators, dynamic operators are assigned to the queues on an application level rather than a PBX level.

Any extension on the PBX can be set as a dynamic operator, not just those already assigned to a queue.

To add an extension that is already an operator on at least one queue, the supervisor can simply right-click on the empty cell that corresponds to the desired queue and selecting Add from the context menu. Similarly, they can remove the operator by right-clicking on the relevant c

If the extension is not an operator on any queue, the supervisor must use the drop-down menu at the end of the column that corresponds to the desired queue. From there they can select the desired extension then click on Add to assign it to the queue as a dynamic operator. A new row will appear displaying information on the new operator.

As with other dynamic operators, the supervisor can simply right-click on the relevant cell to remove the extension from the queue.

FAQ

(Android) After starting the Smartphone, I do not receive incoming calls on Kalliope Phone. What can I do?

The behavior is introduced by Android security settings from version 10 onwards. The terminal is really operational only after unlocking by PIN, sign or biometric reading, the times vary from a few seconds to a few minutes depending on the hardware characteristics of the terminal.

(Android) I am not receiving incoming calls when Kalliope Phone is in the background. What can I do?

Go to Settings > App > Manage App > Kalliope Phone and check that no background usage or power saving restrictions are set. Go to the Play Store, search for the Operator Services (Google LLC) app and make sure you have the latest version installed. Also check that the ports needed for Google to deliver push notifications are not blocked by routers, firewalls, or antiviruses. Read here for more information.

(Xiaomi) Kalliope Phone does not appear in the foreground when I receive incoming calls. What can I do?

Kalliope Phone may not have the necessary permissions to appear in the foreground on the lock screen. Go to Settings > App > Manage App > Kalliope Phone > Other Permissions and make sure the permissions are all enabled.

(Android) The ringtone is not played when I receive an incoming call. What can I do?

In case the ringtone is saved on external storage, Kalliope Phone may not have the necessary permissions to read the audio file. Therefore, you need to go to your smartphone settings and authorize Kalliope Phone to access the phone’s memory. For example, on Samsung terminals, go to Settings > Applications > Kalliope Phone > App Permissions > Memory and select Allow.

I cannot make or receive calls and the message “not registered” is displayed. What can I do?

In case of connecting via mobile data network, make sure you:

you have 3G/4G/LTE coverage
you are not in airplane mode
you have not run out of available Internet traffic

In case of connection via WiFi network, make sure that:

the ports on SBC or PBX used for signaling and audio streams are reachable (depends on installations). Es. 5060 UDP and 10000-20000 UDP on Kalliope IP in case the default Kalliope configurations are used and there is no SBC.
port 443 TCP on the IP address used during configuration is reachable
outbound traffic to IPs 78.152.108.54, 78.152.108.55, 80.93.131.132 and 80.93.131.134 (ports 443 TCP, 24998 TCP and 4998 TCP/UDP) is not blocked

If you continue to have problems, please contact your designated Kalliope specialist technician.

(Android) During installation you are prompted to enable permission to display Kalliope Phone in the foreground, but I cannot change this setting. What can I do?

Check Settings > Applications > Kalliope Phone for the Display Featured item and grant permission. The item may have a different name depending on the model (e.g., show above other apps). If your smartphone does not show such an item or the item is not enabled, it is possible that Android Go, a particular version of Android that is not supported by Kalliope Phone, is installed on your smartphone. You can check this in the following ways:

the version of Android currently installed on your device can be found within the Phone Settings. Remember that the section may have different names depending on the model.
the screen shown when restarting your device should say go edition in addition to powered by Android.
standard applications installed on your smartphone should have the suffix Go in addition to their name (e.g., Google Assistant Go, Gmail Go).
standard app icons may have the word GO in them.

I experience poor audio quality under WiFi network. What can I do?

When connecting over WiFi network, the quality of service (QoS) Voice with Kalliope Phone is dependent on the correct LAN configuration. You can best manage the priority of traffic generated by Kalliope Phone by taking into account that RTP packets are classified and marked (within the TOS, Type Of Service, field) with a DSCP value equal to 46. Make sure that the access-points used allow prioritization of voice packets. If you continue to have problems, contact your Kalliope technical specialist of choice.
