Video preview before answer and an unlock button
Note: Video preview is supported by Legacy Collaboration/ Vision (EOL)/ SuperVision (EOL) / Android mobile app (iOS app is not supported)/ ForcePro 5/ SuperVision 5.
The possibility to add an unlock button can be implemented only for Legacy Collaboration/ Vision (EOL)/ SuperVision (EOL). On other devices (e.g. x-bees, Collaboration 7), you need to manually press the specified DTMF to open the door.
ForcePro 5 and SuperVision 5 are not supported either. In this case, a BLF key with Send DTMF must be configured with the appropriate code. See how to configure a BLF key here: Wildix VoIP Phones 5 User Guide and SuperVision 5 User Guide.
