Switches the call diversity number (1, 2 ...) on or off.
A call diversity for an incoming number has to be created with the Fritz!Box web interface. Requires the API: Telnet, webcm or TR064 (>=6.50).
- Note! The Fritz!Box allows also forwarding in accordance to the calling number. This is not included in this feature.
+ Note! Only a diversity for a concret home number and without filter for the calling number can be set. Hence, an approbriate diversity-reading must exist.
