Remote Phone Call

FAQ

• 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]
  "Enabled"=dword:00000001
  "DisabledByDefault"=dword:00000000

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