The classic setup of Remote Phone consists of two components. Remote Phone Call, the app running as service on the Android phone, and the PC client CallCenter.

Starting with CallCenter 6.0 the PC client alternatively connects to the mobile device via the Bluetooth Handsfree profile. Using the Handsfree profile does not require a running App on your phone. Therefore, also iPhones and nearly all other mobile phones are supported.

The PC client connects to the phone via Bluetooth or for the classic setup with the Android app service alternatively via WiFi.

After establishing a connection, you can manage calls fully from your Microsoft Windows desktop. You can easily dial numbers from phone contacts, from the call history, from the clipboard, from Microsoft Outlook, Word and Excel and manually entered numbers. Further, you can accept and end calls. Using the Android app service or the Bluetooth Message Access Profile (MAP) additionally allows you to write and read SMS messages.

Please take a look at the following feature matrix to decide which setup best suits your needs.

  1. SMS support for the Handsfree setup requires the Bluetooth MAP profile. Functionality differs depending on your mobile device manufacturer. For Android 5 or higher reading and writing messages should work. For iPhone only reading of incoming SMS messages is possible.
  2. WIFI connections may not be stable for newer Android devices because of power saving technics. Bluetooth connections are recommented.
  3. All mobile devices supporting the Bluetooth Handsfree profile.
  4. The PC client CallCenter needs a key for the Bluetooth Handsfree feature only. For connections to a licenced Android App no further key is needed.
  5. For the trial version of the Android App "Remote Phone Call" install Remote Phone Call Trial.

For the classic setup with the Android app we recommend the usage of a Bluetooth headset connected to your phone since call audio is not routed to the PC. In contrast, the Handsfree setup passes audio to the PC and you should use a headset connected to your PC.

Remote Phone Call Trial is offered as full functional 15 day test version on Google Play. Also on Google Play you will find the paid version Remote Phone Call. If Google Play is not available for you, Remote Phone Call LK will be an option. This licence key version can be downloaded from the download section and will work as 15 day trial before a licence key is needed. For the Handsfree setup no Android app is needed and you can just download and install CallCenter on your PC which also allows a free 15 day trial for the Handsfree feature.

Video & Screenshots

Watch our product video which demonstrates how CallCenter and Remote Phone are working together for the classic Android setup. CallCenter works nearly identically for the Handsfree setup. On the left site you can see the screen capture of a real Android device which is controlled remotely from a Windows desktop.

You can see how to start calls on the phone from CallCenter or directly from Microsoft Outlook. Also some details about writing and reading SMS messages, about contact search and various other features are shown.

Extended features

Because of architectural changes of the Android phone runtime extended features are currently deprecated and not available since version 6.1. Many thanks to all testers and your feedback. Maybe extended features for holding/activating calls, dialling DTMF tones, managing conference calls and so on will be available in a later version again.

Since begin of development of Remote Phone Call a full featured remote control of all phone functions was the goal. Although Android is a great development platform, there are some features which cannot be controlled by app developers. For example it is not possible to dial DTMF tones for active calls and to manage foreground, background and conference calls. Even such basic functions like answering and ending calls are not directly offered and may stop working in future Android releases.

Starting with Android 4.4.3 some of this missing functions and with Android 5.0 nearly all features are provided. Unfortunately this new functions are not usable for common app developers. They are only available for device manufactures and for users which owns rooted phones. Nevertheless, the current Remote Phone Call version adds experimental support for extended call management functions.

Please help and vote for a new Android feature that would allow to offer these extended functions also for non-rooted phones.

Additional features

  • Hold/Activate calls
  • Dial a second call
  • Manage conference calls
  • Dial DTMF tones
  • Shows current call duration


  • Android 4.4.3 or above
  • A rooted phone
  • Remote Phone installed as system app within system/priv-app (see below)

Install Remote Phone as system app

Installation of Remote Phone Call as system app is only possible on rooted phones or on devices with unlocked bootloader and installed extended recovery tools. Please note that rooting or unlocking can lead to severe damages of device and loss of warranty. WE ARE NOT RESPONSABLE FOR DAMAGS OF YOUR DEVICE OR ANY DATA LOSS. Help and vote to make this available for non-rooted phones too.

This is a brief instruction of two possible ways of moving the Remte Phone apk file to the system/priv-app folder which will give the needed permissions for extended features. For more details please do some web researche about this topic. ex.: "How to install any App as a system app on Android"

  1. Install Remote Phone on your device as usual. Open the settings screen of Remote Phone and verify that the "Enable extended feature"-option is visible but not enabled for activation. In the case the option is not visible, your device does not support extended features and is probably running an Android version below 4.4.3 or a the Remote Phone version is below 5.5.
  2. If a exteded recovery tool is installed, perform a complete system backup.
  3. Install the app ES File Explorer or a compareable file explorer with root support on your phone.
  4. Open ES File Explorer and activate the "Root Explorer" option under tools.
  5. Go to the folder "/data/app".
  6. On an Android 4 device look for the "justPhone.remotePhone...apk" and perform a cut-operation on the apk-file. For Android 5 look for the "" folder and cut the folder.
  7. Go to the folder "/system/priv-app".
  8. Perform a past-operation.
  9. Reboot your phone.
  10. Start Remote Phone and verify, that the "Enable extended feature"-option is now enabled for activation.
  1. Install Remote Phone on your device as usual. Open the settings screen of Remote Phone and verify that the "Enable extended feature"-option is visible but not enabled for activation. In the case the option is not visible, your device does not support extended features and is probably running an Android version below 4.4.3 or a Remote Phone version is below 5.5.
  2. Boot into recovery mode and perform a complete system backup.
  3. Within recovery tool: mount your system image for write access
  4. Open a shell with root access on your PC via ADB or with a shell offered by your recovery tool if available.
  5. Use common shell commands and change the current folder to "/data/app".
  6. On a Android 4 device look for the "justPhone.remotePhone...apk"-file, for Android 5 look for the ""-folder and move the apk-file respectively the folder to "/system/priv-app
  7. Reboot your phone.
  8. Start Remote Phone and verify, that the "Enable extended feature"-option is now enabled for activation.


  • Can I use the PC microphone and speakers?

    For the Handsfree setup the answer is yes. But for the classic setup with the Android service this is not possible. The Android platform doesn't allow this for app developers. Therefore we recommend to use a Bluetooth headset directly connected to your phone for best results. As an example of such a headset look at our product picture. We have an eye on this but we don't think that one of the next Android releases will make this possible.

  • Can I dial numbers while a call is active?

    Unfortunately dialing DTMF tones for active calls is not possible for app developers on non-rooted Android phones. Starting with Android 4.4.3 experimental support for rooted phones was added to Remote Phone call. For details please see extended features. For the Handsfree setup dailing DTMF tones would be possible but is currently not implemented. This feature may be available in one of the next releases.

  • Is Remote Phone Call available for iPhone or other non-Android devices?

    Yes, you need to use the Handsfree connection type of CallCenter. Connections to the Remote Phone Call app service is only available for Android. Currently only Android gives us the needed public features on the programing interface.

  • Are clients available for non-Microsoft Windows platforms?

    Currently the only client platform is Microsoft Windows. This is because we have invested a considerable amount of time to implement a client which integrates as seamless as possible into your desktop environment. But this comes with the price of a platform dependent client. Clients for other platforms are currently not planned for the near future.

  • Why do WiFi connections consume more battery power than Bluetooth connections?

    While the phone service is waiting for a new WiFi client or while it is connected via WiFi a CPU wake look needs to be held. Otherwise the phone would not be reachable or the connection would be lost. This wake lock for the main CPU is not needed for Bluetooth connections since the Bluetooth chip does the job. This saves power. In the case you use WiFi while your phone is not plugged to the power supply without the usage of CallCenter, you should stop the phone service and eventually disable the auto start option. In the case your PC is Bluetooth enabled you should prefer Bluetooth in preference to WiFi.

  • Does CallCenter work with Remote Desktop sessions?

    Yes! CallCenter can be started once per user session. But of course, for server environments CallCenter could only use WiFi for phone connections and therfore Handsfree connections are not supported.

  • Can CallCenter be connected to the phone via a USB cable?

    No, sorry, this is not possible.

  • Can CallCenter cause bad WiFi performance?

    Unfortunately for some environments temporary, yes. Some Bluetooth/WiFi chipsets reduce the WiFi performance dramatically while a Bluetooth device search is performed. This should lead to better Bluetooth results since Bluetooth and WiFi use the same radio frequencies. CallCenter needs such lookups while waiting for a Bluetooth client. The problem disappears immediately after a connection has been established. As workaround for affected systems you should stop CallCenter from waiting for a Bluetooth phone connection while no phone is available. Just click on the status line at the head of the CallCenter main window. Click again for restarting the search.

  • Which licence type do I need?

    The needed licence type depends on your needed setup.

    For the classic setup via the Android service you would need to buy a Google Play licence for the app Remote Phone Call or, if Google Play is not an option for you, you could buy a licence key for the Android app Remote Phone Call LK. The LK key must be entered on the settings screen of Remote Phone Call LK on your phone. In both cases you do not need any further licence. The PC client CallCenter is free for connections to a licenced Android app.

    For the Handsfree setup no app is needed. So, you need to buy a licence key for the Handsfree feature of CallCenter. This key must be entered on the PC-clients settings screen.

    In the rare case you want to use both setup types, the classic setup with the Android app and the Handsfree setup, you would need to buy one of our Android app licences and a licence key for the Handsfree feature. But normally, you will need just one of the two possible setups. Look at our feature matrix to decide which setup best suits your needs.

  • Are the purchased licences time limited?

    No, there are no time limits for our licences.

  • I got the message "Error downloading license certificate" for my Handsfree licence. What can I do?

    To fix this error you need to upgrade to CallCenter 6.7 or above. In the case you are still using Windows 7, for which official support ended in January 2020, you need also to create following registry keys:

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]

    After that a reboot is require. For further details how to enable TLS1.2 support for Windows 7 clients please see tls-registry-settings.
