Or just call phone number can be found at [...] All Explaining the program under [...] !!! Hello, I have the Fritz box tested all the apps to control and query, to BoxToGo no one comes ran! You can: - view his call lists - control the voice mail, call forwarding, reverse lookup, WLAN and WOL - use its Android to display and announcement of the caller - the Phonebook on the fritz box care - Create widgets fritz.box to control - and so (! see description). All functions can be operated via WLAN, but also by traveling over the Internet. The developer is responsible for questions and suggestions to reach over and developed the program continually. Hardly changes the firmware of AVM Fritz box, already comes a new version of BoxToGo. The waiting time for a new version is no longer than one night. This program is more than worth the money!
