have the C 3 added myself to access quickly without a PC to the Fritz box. Still have div. Older Giga Set phones in operation, with which this is only partly or not at all possible. All functions as well as start-up are excellent and meet the standard Fritz: the things just work. Very nice is particularly the access to the phone book entries in the 7390, they are thus maintained in only one place and are verfügbaar everywhere at Fritz phones used. Only I see a disadvantage that the phone can not be stood upright, unless you put it in the charging cradle. I often speak with telephone calls free (teleconferencing ...) sounds the unit "something around the corner", as speaker then sonicated the desk !. Holding this point as one flaw and therefore no deduction from the estimates given by me 5 stars. Conclusion: Will my located currently still in operation Giga set replace equipment through this.
