Call bindings
The call binding function allows calls from specific phone numbers (e.g. calls from the door) to be linked to a camera and up to two function keys. For example, a call binding can be used to open a door or switch on a light.
Note: In the COMfortel D-100/D-110/D-200/D-210, setting up a call link is only possible via provisioning.
