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 (currently available only on iOS).

KalliopeCTI mobile is available on Google Play and the App Store.

N.B.: Each extension can only be linked to one KCTI account.

Call history

Call history

  • Missed calls

Calls are grouped based on the called or calling contact/number, and the total number of calls is shown in parentheses.

Call management

Inbound calls in call-back mode (Android and iOS)

Inbound call notification

For inbound calls to the extension, will send a notification to the mobile app and the screen shown in the picture to the right will be displayed.

As they use the official notification engine of their operating systems, these notifications will be sent even when the app is closed.

This screen lets you select one of three options:

  • Slide down: the call will be ignored, the notification on mobile will be silenced, and the extension will keep ringing.
  • Transfer to mobile: the extension will stop ringing; the PBX will contextually establish a call to the mobile number linked to the user by the system admin from the extensions configuration page. The call will arrive to the mobile SIM dislpaying the geographic number of the line associated to KalliopePBX as the sender. By answering this call you will begin conversation with the caller. This call forward is completely transparent to the caller, who will hear the ringing tone for the entire duration.
  • Refuse: the PBX will refuse the call and the extension will stop ringing.

Inbound calls in Softphone mode (iOS only)

Notifica chiamata in ingresso CallKit

For inbound calls to the extension, will send a push CallKit notification that will trigger the standard inbound call screen as shown in the picture.

These notifications will arrive even when the app is closed, so you can be on call even when the sartphone is on standby.

This screen lets you select one of two options:

  • Refuse: the PBX will refuse the call and the extension will stop ringing.
  • Accept: the KalliopeCTI app will wake up in softphone mode, the "Active call" screen will be displayed, and the SIP call will be established directly via the app. The smartphone will effectively become an extension of KalliopePBX.
Chiamata in corso in modalità softphone

The caller name and number are displayed on the top of the "Active call" screen, and on the bottom of the scrreen you can find the buttons to activate the available features:

  • Pause: the call is put on hold. You can take the call off hold with the same button.
  • Call transfer: performs a blind call transfer to another number (extension or external).
  • Bluetooth: enable/disable bluetooh earpiece.
  • Speakerphone: enable/disable speakerphone.
  • Keypad: displayed the numeric keypad (e.g. in order to navigate an IVR menu).
  • Mute: enable/disable the microphone.

Outbound calls

KalliopeCTI offers three options for setting up outbound calls in call-back mode.


The first icon from the left lets you use the click-to-call service. The landline phone linked to the extension will receive a call from the PBX where the caller is c2c: called number. Answering this call will establish a new call to the desired number.


The callback service lets you call directly from your mobile phone using the PBX lines. When you tap the center button the PBX will call the mobile number linked to the extension. By pressing 1 when prompted by the audio guide you will begin communication with the desired number.

Using the device SIM

With this option, the call will be made directly from the SIM card of the mobile phone on which the KalliopeCTI app is installed.

Outbound calls in Softphone mode (iOS only)

Outbound calls in softphone mode will be sent directly from the app via SIP.

The click-to-call and using the device SIM call setup mode will remain available, but callback mode is replaced by the direct call through SIP.

Dialing a number directly from the keypad will establish a call via SIP. Once the call is established, the "Active call" screen will automatically be displayed.


Aside from searching the phonebook, you can also dial the number you wish to call with Kalliope directly on the KalliopeCTI mobile app keypad. While dialing, you will be shown autocomplete¹ suggestions.

In call-back mode: Tapping the call button lets you choose which mode to use among the ones listed above.

In softphone mode: Tapping the call button will directly establish a SIP call.

N.B.: The KalliopeCTI keypad does not automatically add the outbound prefix. You will need to dial the number as you would on a landline phone.

¹ Feature only available on Android.



On Android, you can access the KalliopeCTI app services by tapping the gear icon in the lower right. On iOS, you can access them via the system menu.

Three services are currently available: presence (seen above), unconditional forward, and fork to mobile.

Unconditional forward

Unconditional forward lets you set an extension number to which to automatically forward all inbound calls (this feature only applies to calls made directly to the extension and not those originating from groups or queues).

This service is useful when you are not available but wish to redirect inbound calls so they can be dealt with.

To enable the unconditional forward service, simply tap the arrow icon, input the extension number to which you wish to forward calls, and save.

When this service is enabled, the icon will change color, and a notification will be shown containing the number calls are being redirected to.

To disable this service, simply tap on the arrow icon again.

Fork to mobile

With the fork to mobile service, a call to an extension is presented to the mobile number linked to it as well.

Answering the call on the mobile phone will cause the extension to stop ringing, and vice versa.

To enable the service, simply tap its icon. As with unconditional forward, the color of the icon indicates the status of the service.

Privacy Policy

Secure connection

In order to offer its services (e.g. telephony, real-time notifications, chat), KalliopeCTI must be able to communicate with KalliopePBX. This communication is made through an encrypted connection, guaranteeing the security of transmitted personal data and messages.


You can give KalliopeCTI permission to access the contacts on your device. The saved contact data will only be used within the app and will never be sent to KalliopePBX or exchanged with other users, except for the information required to make calls via the PBX.

Phone number

In order to use the mobile features of KalliopeCTI, you must first insert your phone number in the KalliopePBX configuration page. This number will then be verified by KalliopeCTI and compared to the number of the SIM card in the device.


KalliopeCTI will access the phone's memory in order to send diagnostic data to the KalliopePBX developers via email. This data will only be sent when the user selects the "Send report" item in the KalliopeCTI menu.
