When not resting on its base for charging, it is in my pocket (or in that of a colleague).
Easy to recognize and hear (you can set the ringtone and even put it on silent) when it rings, just press the button with the "green phone" to win and take the call. To hang up, just as easy, simply press the red phone (in months that the speaker does so before).
The base having a large worn, no need to worry about the fact of receiving or not communication.
Being on the ground floor with the base on the 3rd floor, communications are not "false note". It does not cut (even in elevator).
A good phone that completed these missions.
With also a handy directory that associates a name with figures like that just type it (if we remember what it is)
One can also choose a different ringtone for a name given in directory. What is good rpatique to identify a call when no is watching it.
