Identification during a SIP Call
It is possible to configure iDFace to keep identifying users while it is in the middle of a SIP call. Go to [MENU] -> [INTERCOM] -> [CALL SETTINGS] -> [NEXT] -> [NEXT] -> [NEXT] and check "Facial identification during the call" to enable this feature.
With this feature enabled, the device will execute facial identification during SIP calls. You will be able to view the incoming/ongoing call with the call information alongside with facial identification feedback.
